  5. dying leaves

    From the album Sick plant

    yellowing leaves with brown patches, tips also curl inward
  6. These plans are 3 weeks old. they been in these 1 litre pots for 2 weeks(tomorrow) some of the plants have developed yellow leaves/yellowing I first thought it may be cold roots so I’ve raised the containers up on wood and have Tube heaters each side. the Room is 27c lights on 23c lights off just checked Root Temps just before lights came on and 19-21c the Four Green plants in one pot are PINK Kush then the other four which are the ones that worry me with yellow are 1 x pink Kush 1 x Gorilla Zkittles 2 x Pineapple Chunk all 8 are Biobizz light mix, I rotated the four with the other 4 incase it was a light issue light above them is 600w HPS Any ideas? the roots been up off cold floor now 5 days so not sure if it is that?
  7. So Mr Paranoid is back again pmsl ....last feed on the 18th I gave in and mixed some grow feed in (intense soil grow half strength 1.5ml / litre) to go with the intense foundation (4ml/litre) and calmag (1ml/litre). 24 hours later I had some yellowing on the tips of the new growth .. oops. However they seem to have recovered nicely ! No more feed for them just the calmag and foundation for now ! Yesterday evening the bottom leaves had started turning yellow eeek ! It was watering time (was 1/4 litre every 4 days) however they seemed drier than normal so upped it to 1/2 litre each of jug filtered water with nothing in (very hard water area however a jug filter takes the worst off ..not ideal but seems ok). Checking the temps they were high .. roots were 26.1 C, ambient 28-29.8 C, RH 40 % but they have always been high. I bypassed the variac and put extraction on full and intake on full (it's on a low setting on the unit by jumper so still negative pressure). I adjusted the heat mat to kick in at 22C instead of 24C. Temps today are 25.1 at the roots, 26.7 ambient., 37-39% RH. All three are showing a some yellowing though only on the bottom leaves. Lighting is at 352W LED (wall measurement) . Tent is 4x2x5 . There is a small axial fan blowing air from top to bottom via a diffuser. May change this to a normal fan . Not sure if this is natural or if something is going wrong - if so I would really like to sort it asap - been really pleased with this as a first grow (in the diaries section) . The three plants that are smaller (not in photo) are a week behind and other than one thats a bit of a mutant don't seem to have the issue . Thank's everyone .. look forward to hearing any thoughts before I try and take any remedial action (no idea so thought I had better hold off !) Thanks Compz
  8. 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?
  9. 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
  10. 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...
  11. 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.

  19. 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

  22. 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
  23. 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?!
  24. 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.
