  1. My plant hasn't grown taller for about a month. Ive not given it nutes because the first time i did it burnt the ends of the leaves. So ive just been watering lightly as to not flood it. I checked it this morning and the leaves have yellowed. Its like it started to bud already as it smells in my grow area but its only a few inches tall. Any idea how to get it too grow taller and to counter the leaves?
  2. Hi Guys, My auto plant is 2 to 3 weeks into flowering. Naturally some of the lower fan leaves have turned yellow and fell off. However two thirds of the way up the plant, a few of the large fan leaves have started to turn yellow. Can I ask, is this the start of a nitrogen deficiency? If so, what suitable flowering nutrients can I give it at this stage? Many thanks
  3. Hi all can anyone help with identifying the problems with the leaves in this picture? It is only on the lower bigger leaves atm. Using Biobizz range with all mix. Been reading a lot about mag deficiency at week 3 of flower which is where I happen to be but this doesn't look the same as the pictures I've seen that show mag deficiency...
  4. So guys my first grow and I'm currently in wk6 day 6 of flower and the last couple of days I've noticed some yellowing leaves and I need some help understanding what could be the problem/s. I'll try to keep it short. I ran into a few minor issues along the way but have been browsing the forums often to gain as much knowledge as I can swallow. My setup is currently in my loft - 60x60x140 tent - 4inch intake fan and carbon filter exhaust. - 6"fan internal - Viparspectra 250hp led (recent addition before was using a cheap 600w that came with the tent) - Vitalink 100% coir - advanced nutrients sensi a&b bloom, sensi a&b grow coco formula, big bud, overdrive. I've been using half the recommend dosage throughout veg and flower and slowly been increasing. I used big bud for the first 4 weeks and now mid wk6 started using overdrive. - temps were a nightmare to start as they were planted in mid-late feb but now it goes between 21-30. - humidity between 30-40% depending on weather as my intake is connected to my soft - plants are 3 seeds which came from a batch I got from my guy. I'm guessing they could've came from a hermie, after reading the forums worried mine would too but they haven't and all female. - watering I use a soil moisture meter to try and better tell when the coir is dry, typically its every 3-4 days If any more info is needed or I missed something please ask. There is a few things I know I will change like next grow I will only do the 1 as the tent is quite small and they do look a bit cramped. I was also going to do an autoflower as they grow smaller. Some other info that might help determine the cause of the leaves. I recently changed my light from a cheap 600w led that could literally been on top of the plants and no burn to a viparspectra 250hp and I'm worried it may he light burn but the yellow leaves aren't limited to the center. I also started feeding overdrive so I thought maybe a toxicity but it's the top leaves that seem to be affected. I was thinking I could do a flush anyway which would mean bringing them down from the loft. Anyway pictures below, look forward to your wisdom

    Hi all, ive attached some photos of some yellow leaves I’m experiencing on some casey jones.. the photos aren’t great but hopefully you can see the issue. Hoping to fix the sick plant before she goes into flowering. All the other ladies are absolutely fine, under pretty much the exact same conditions. Any advice would be helpful.

  9. Hi All, I have two plants growing outside in pots.After good initial growth I tainted the soil by adding chicken manure pellets. Some of the leaves have now yellowed and have large brown spots. Is there anything I can do to save the plants? They are 3 months.Could they survive repotting in new soil?

  12. Hello fellow growers, This is my first grow and I am having problems with my plants. I planted them 2 and a half weeks ago and until now they seemed very healthy, but for the last couple of days, the leaves on one plant are turning yellow. I haven't used any fertilizer yet and I water them approximately every 5 days. Also, the plants seem a bit short, is this normal? Any advice would be very welcome. Here is a picture of the sick plant. Many thanks

  15. Hi guys, having a few probs hope someone can help. Got my first coco/rtw started but I'm getting slow growth and leaves are turning yellow. I've previously done DWC but thought coco would be easier. So setup is 10 X s/queen#1 in air pots Hand watering 1l daily with formulex/regenaroot/mighty grow. EC 1.0 PH 5.9 getting quite a bit of runoff. 2 X 400w increasing to 3 X 600 Temp 25-27 lights off 19 Pots are probably too big for them but I had to transplant early as they were getting v leggy Any help / advice appreciated
  16. Welkommen... I swear to God I think about posting on here every other day but never really get around to the execution I know what you must be thinking - he's gotta be a lousy grower for sure! Yeah ... you're probably right there too! haha So basically I popped a few seeds back in January ended up with 4 plants in a garage (improvised) in the dead cold of the winter surrounded by spiders and stuff.. We are in Coco 600 120 tent feeding lightly and infrequently (every 2 days or so) heavy-ish watering in veg. Light waterings flower. None of the above details are by choice its just what happened. Like my birth probably! hah Right so off to the races I reckon i'm in for a chop today I will post pics very shortly! Lots of yellow leaves so beware. constructive critics are welcome though! Who's out here?!
  17. Hi I've already posted on here a week ago or so because I have an issue with the leaves turning yellow on my blue treacle autoflower. She's now 3 weeks or more into flowering. I had an issue with temps being too low during lights out. I've now sorted that with Changing the light cycle to 24/0. The problem I have is that 90% of the leaves are yellow. Completely different to my other plants I have growing. She's still growing mind, slowly but defo still growing. I'm watering every 2 or 3 days, whenever she feels dry with 1ltr water 4ml biogrow and 5ml biobloom. Even gave some epsom salts aswell. Nothing is changing tho . the temps remain between 27c and 30c.if anybody can can give me some advice I'd appreciate it. Thanks.

  19. Good day to all I am currently growing 5 plants in a 120x60x180 tent with 2 x 250w hps. When initially put into my set up they were 12 inch tall and healthy, I put them in 11 litre pots with canna terra professional plus soil and fed only water every other day. To begin with they show normal growth and seemed to be fine, but around 2 weeks ago they started to yellow and slow in growth. I had not long finished a grow using the exact same set up, the only thing i can see that has changed is the time of year. i.e. the cold weather. I have insulated the pots and used 2 1 ft green house heaters and the temps have been fine for the past week or so. But still getting worse... Im starting to think its a problem with the soil / up take of nutes? Can anyone give any advice? Thanks in advance, John
  20. Hello everyone! I have been nuturing a small sativa for a while now and it hasnt been a smooth sailing to say the least! I have some questions that perhaps someone here on the forums could help answer. . . So first a bit about the little baby: its a small pot plant grow, diameter +- 10-15cm, depth +- 15-17cm (so its small) started with a ultra-crap compact soil (from garden center) for seedlings. not much in the way of nutrients in there sprouted around August it has been through some cold weather and dry spells I fed it with some worm castings mix (very lightly though) I transplanted it to better soil ("herb" soil which is light and fluffy with slow release nutes, i havent subsequently fed it) and I added vermiculite too I topped it around 1-1.5 months into veg stage (it had 3 nodes when i did) it has been into flowering now for around 17 days & has formed 2 nice little, little, tiny buds My aim was to have a small patio grow with maybe enough end product for a couple of smokes. Nothing hectic. So the issues started happening when I had it in the crappy 'hard' soil. It was not draining much and I suspect it developed some root problems there. So I transplanted it to the fluffier soil with added vermiculite. It seemed much happier. That was about 3 weeks ago. Now, I am seeing the old growth (bottom leaves) going yellow, curling downwards, and the leaf tips starting to decompose moving inwards. Take a look here: Notice the curled leaves... Here are some shots of the plant as a whole: So I am thinking this is a Nitrogen deficiency but im not 100% sure. . . & i dont want to add any if its not needed. Also the possible root damage might be an issue too. Another thing I can think of is that the plant is using up those leaves to provide for the buds? Not sure. . . Does anyone have an opinion as to what may be causing this? Thanks alot guys!!!
  21. Hi Troops, When in flower and with a thick canopy that the light cant penetrate I always thought it was normal for the lower leaves to turn yellow and drop off but i stumbeled across a website that says this is a nitrogen deficiency ?I grow in coco and just thought this was a normal part of the process. confused dot com ?
  22. The leaves are turning yellow with like yellow spots that then turn brown, then they die completely, what is this its spreading im 3 weeks in to flower as well so dont really want to have to start again im 7 weeks in altogether, any help?
  23. So opened up to feed today and was greeted to see my plants going yellow mostly on the bottom leaves. I haven't trimmed them at all and they are getting pretty bushy so I'm hoping this problem is an easily solvable one e.g. giving it a trim or maybe water less/more. I water about once every 3 days and my watering cycle goes like this. (day 1. nutes, day 4. nutes, day 7. nutes, day 10. Ph'd water 6.5-ish) here's pics of the problem, advice would be appreciated if you know what the problem is.
  24. Hey all, this has slowly developed over a few days. At first I thought it was the brightness of the 600w hps light reflecting but now its obvious. I planted two beans, one of which turned out to be a twin and the bigger one is the one with a couple of yellow leaves. They've been fed on three part advanced nutrients every two days and are in 40 litre flexi buckets. Any experiences or advice is really appreciated.
