definitely cal mag deficiency but the causes can be many, be careful with this wood you have underneath, may be impregnated with chemicals, I had a problem like yours for 6 months and I could not find the problem, finally it was a plastic floor that I had put and it released ethane and it killed my plants
Kush_queenanswered grow question 4y ago
Yeah I have removed the wood now anyway but I never thought of that and I am going to foliar spray with calmag 🙏

looks like magnesium deficiency, of course it would be and nutrient lock because your top and the rest of the plant is thick

Drooping leavesLook at the right angle droop on the leaves at the very top of this RQS fat banana automatic. I have six plants in my cupboard. 5 fat bananas and a northern light auto. Two fat bananas have right angle drooping. I’m thinking over watering or too hot - 28 degrees. Any idea? Thanks

Dark shiny leaves, Clawing towards the ends. Is this a sign of N toxicity?Hello, I am a first time grower. I have plants going in Fox Farm Happy Frog soil with 4-4-4 Gaia greens dry amendments. I believe the soil is too “hot” and wanted to get your guys thoughts if you agree and if so, what to do. I water every 2-3 days using the knuckle test. Thanks!

Botton leaves are turning yellow then fading awaySome bottom leaves of my three plants are turning yellow, it looks to me that they don't have enough nitrogen.
I have tried to double biobizz nutriment the last two times I have watered them but it doens't seems to make any difference.
What can cause this issue ? Thank you
