Is this some kind of deficiency?
BraveheartGeneticsanswered grow question 4 years ago
Hi mate, I think thats the start of light burn. The edges are the only parts affected. You can see they are nearly curling up. I would lower the intensity or raise your light a few inches and see how she responds. Good luck and happy growing

Yes, looks to be the beginning of a magnesium deficiency. In coco you have to add cal-mag almost every other feed. AN Sensi Cal-Mag has a fair amount of nitrogen, so be careful if that’s what you use. Epsom Salt is another cheap source. Just dissolve a tablespoon per gallon of water before you add anything else. It’s just we’re they are kicking into flower gear and about to stretch for the light a little. Hope that helps and happy growing!!!

I'm hesitant to defoliate since this is my first auto grow but the blueberry is damn bushy the tangerine dream could use a touch up too. Would you remove all the big fan leaves, half of them or what would you recommend? Tucking/tying down leaves is no issue if low stress is key.Week 8

Defoliation of Fan leaves. The COBRA's growth structure is very tight nodes with large, Indica-type fan leaves. The largest one (3rd pic) has tripled in size from the last photo. I have been bending the leaves under side-branches. Can or should I cut them off to allow light in?Week 2

I'm on Week 7 & more leaves are rapidly turning yellow. The stems are also a deep red/purple color on said yellow leaves. I plan on going until Week 11-12 with her but can't give nitrogen at this stage of flowering. Anything else I could try? Or is this normal?
Thanks! 😛Week 7

Each plant seems to be suffering from some sort of deficiency/lockout. I thought the 4AM & 3BOG looked hungry but no improvement after 2 days. Sour Stompers still losing leaves but their buds are MUCH fatter and frosty than the other 2. Maybe just different flowering times.Week 7

Anyone ever try using the last week of vegetative growth's feeding schedule during the first week of flowering? Decided to try it out since the plants will be growing more vegetation than focusing on flowering during the first week after flipping. At least that's what I assume.Week 9
