Yes o had some heat issues when the girls were stretching , and some curved leafs are from my packed wardrobe grow, probably leafs agains the walls. Ph under control I will cut nutes for a week I see if was a lockout due too much nutes

Hi there, Not very sure you have deficiency or toxicity.But I see your plant suffering from heat stress and nutrient burns.Those curling leaves indicate the heat stress and those yellowish tips indicate nutrient burn.So I would recommend to lower down your temperature by raising your light or adding more ventilation.And slow on nutrient usage.Also don’t forget to check your water and run off pH.Most of the problems occur because of improper pH.Happy growing... ✌️

Hi there BRLGrow, that's typical of magnesium deficiency , you can tell from the yellowing of the serrated edges of the leafs , you would probably do well to increase you cal-mag a bit . The best is to reduce your light cycle as much as you can (to 12-14 hours) that's because the plant needs more magnesium than possible when it's under such a heavy light schedule. If you do both these things the problem will stop spreading immediately and the plant will recover quite fast. Hope this helps ! 🚀

Thx @Bulbi. What you mean by reduce light schedule? I am on 18/6 since germination

Hey there BRL, you’re right that at this time in the flowering the plant needs K. But the yellowing is still magnesium deficiency . Same reason as before , and the reason for that is that there is a fair amount of “inertia” meaning it takes some time for the problem to stop spreading , the plant to recover , etc. You might be better off reducing yet further the light schedule , or try to muscle through by increasing a bit more the cal mag ... It's a tough thing to bounce back from a mistake on growing , that's the problem. Hope this helps.! 🚀

With you having previous issues patience is going to be key, it also looks as if they are suffering from light/heat stress you can tell by how the leaves are pointing upward.
