Leaves full of brown spotsMy friend doesn’t have a grow diary but he uses advanced nutrients and feeds when almost dry. He has this problem on his leaves and he can’t seem to stop it. I suggested calmag but he feed it 2ml per litre on sunday and the problem is still increasing. What else can he do ?Leaves. Color - Yellow

Should I cut the dried leaves at the bottom?Should I remove the dried leaf in the bottom? I was thinking that it might redirect unnecessary energy to the plant since the leaf might be too far gone to save. I was thinking of starting topping next week as well, when the fifth node start to show more.5y ago

Nutrient Lockout or Nitrogen deficiency (i.e need more nutes) or Fungus (see stems)My leaves are yellow but some are turning green. Do they need more nutrients or lockout? I have not gone above 1EC but have seen both strains handling 1.5EC+ in other diaries. All three plants are drinking the water in trays.

If this was yours, how would you proceed?Going into week 6. I just clipped the bad leaves that show in the picture and will be switching to the growing stage. I plan to do the 36 hours of darkness first. Already changed the water and it has the bloom solution instead of the grow solution. What would you do now?6y ago

Day 49 yellow leavesIs it normal for the leaves to turn this yellow with burnt tips at day 49 of flower. I cut the nutrients about 4 days ago and the leaves have yellow out for the pure kush this much but not really for the Dos Si Dos 33. The pure kush also looks like it has at least 3 weeks to go?Week 16
