Hey Guys, So im leading up to going into flower and i have got my 1st problem with plant 1 since starting 10 weeks ago. After doing some research it looks to me like a Magnesium deficiency but i need your help to diagnose this properly as i think it could also be a Potassium deficiency but dont trust my novice knowledge enough yet, can you help? Last feed was on the 8th September (i know that might seem ages but the plants seem to want fed every 4-5 days) and i am feeding again today, that feed consisted of the following: Grow (GK) 2ml per litre BatBoost (GK) 1ml per litre CM 0.5ml per litre They are on 600W light with no issues 65% Humidity and Root temps are around 23-26 Degrees C Ambient Room Temp around 27-30 Degrees C depending on outdoor weather (it drops below 25 Degrees C when lights are out and Night time.

So all 3 of my GC auto plants are now on day 52 and all now seem to be showing the same unhealthy signs. Is this perhaps a Calcium deficiency? I have a box of epsom salts in the cupboard, should I add some of this to the next watering? Below is an old fan leaf from the smallest of 3 plants, now beginning to show similar signs as the other 2 have shown. I think it will start yellowing like the other 2 have soon; And here is a leaf from one of the 2 larger plants where the issue is more developed and widespread.

Hi,If anyone With experience could give me some advise id be very grateful.Ive got 4 girls on the grow which are 7 weeks from seed which ive just switched into flower now.I potted them from seed straight into canna terra pro and plants developed well with no problems apart from a little bit of nitrogen toxicity which my plants grew out of.Im on week 7 and have not added any any extra nutrients of any kind. Ive literally just watered at a ph of 6.3, using real lemon juice to lower ph from my tap water.I live in a soft water area in uk so water is decent and i let chlorine evaporate for 24hr before watering.anyway, i’ll get to the point.....I want to stay organic so decided to buy these products to add to my plants but not sure on dosages etc.Guanokalong bat guano NPK 1.10.1ecothrive charge NPK 3.2.3Bone meal NPK 3.9.0 / calciumEpsom saltsWorm castingsGuanokalong palm tree ashes NPK 0.3.14Would this be too hot as a tea or could i bubble some in tea and top dress the rest to be watered in ?im using the kingbo 2000W led light ans have heard that led’s such the calmag out of your plants. Im also noticing purple veins travelling through the plant too so not sure what to do as i dont want to use chemicals like calmag.my growing conditions are good.Room temperature day time is approx 22•cRH / 55%....night time temp 18•c RH / 60 - 65 %but ive bought a dehumidifier to control it better.If anyone could help me id be very appreciative and can also add pictures but because of the led purples lighting its hard to see properly.Any feedback would be much appreciated, thanks

Hi everyone, Basically looking for ways to build up my coco, I have canna range a+b, boost, pk13/14, zym, rhizo....im sure I will be lacking in magnesium and possibly other things, I have biosys as a tea for microbes. So based on what I have, what slow release additives can I use that won't impact negatively on canna feed? the idea is to slowly become less dependent on the canna feeds, look forward to replies I have no doubt this may have been asked elsewhere so by all means direct to straight to a thread, the search function is slowing me down on here, 90s delays, topic all content etc sure you all know what i mean

Hi, I have four cuttings of Elvis - very robust and problem free grow - and all four are showing yellowing new growth. Problem in more detail: - Yellowing from the stem, outward to the tips - New nodes growing tight together (stunting) - Central leaf viens and stems sowing purple - Some leaf tip burn Background: - The cuttings were held small for around 8weeks. - Potted up into 3lt pots 10 days ago - problems showed in the last 2 days. - Feed is ec1.2 - 10ml Ionic grow and 1ml calmag (mum was on ec2). - Pots are 22.4c at base lights on and no less than 20c lights off - I have not been able to probe into the middle of the medium. Ambient temps are nice. - Water ph is a little alkaline, but Elvis mum showed no issues at all - perhaps the water supply has changed?? I have some ideas - nute lockout causing iron def - or possibly mag def (doesn't really look like mag def to me though) - but hope someone can confirm or shed light on the problem... Their mum grew out in an 11lt pot (so better resistance to temp shifts) and had no issues whatsoever throughout the whole grow - water and feed are the same for the mum as for the cuttings. I lieu of a better one, my plan is to flush tomorrow and start them back on a 0.7ec feed... Many thanks for any thoughts!

Hi all, I have a head scratcher. I have 6 x skunk #1 in my room, all fed via drip irrigation 3 times per day until 30% run off, all in 8L fabric pots. I have 2 x 600w air cooled HPS lights and one 1200MarsHydro LED (600w equivalent). Nutrients are simple Canna A and B, Sumo boost, and Buddhas tree PK 9-18 as I am 3 weeks from harvest. I have good extraction, fresh air coming in from outside (loft grow), and fan ossilating around. 5 out of 6 plants look awesome, no problems, stems are like chair legs but one plant, in the middle, started with a orange/brown rusting on the bottom fan leaves just after I turned to flower. I did plenty of flushing, as first I thought maybe this plant might have locked out but as time has gone on I would say 80% of this plant is now infected with this dying, rusty leaves. However my buds are just as good as the other plants, and it might well be okay. Also the stem on this plant is also a bit rusty tainted. I just cant seem to diagnose it from looking at charts, its a bad case of whatever it is. I am ruling out rust rot, as I have rubbed the leaves and it hasnt come onto my hands, and my temperatures and nice and comfy, ranging from 23degrees daytime to 18 nightime, and my humidity is under 50%. The closest I have seen on a chart is calcium deficiency, but calcium is an immobile nutrient and deficiencies would start with the top leaves. Magnesium is a possibility I cant rule out, I have a bottle of plant magic magne cal on the way as another troubleshoot. I have some pictures attached, however the light isnt the best, girlfriends don't make good photo takers, but you can make out whats going down. Any feed back helps as always. Thanks

Cacao Nibs are one of the highest sources of Magnesium, 1400% RDA for its weight, I've read somewhere. So the next crazy ChB cultivation advancement experiment, along with my Shilajit Powder Tests, is amending the soil of a few of my spare cuttings with some ground cacao nib powder. I wonder if the product has the ability to impart a chocolate flavoring????? Keep y'all posted!!! peace n pieces ChB
