Strange yellow spots
Nor_Cal_Kannablissanswered grow question 4 years ago
According to your log your pH is a bit high.. this can cause a lockout of iron which it looks like what its doing.. shoot between 6.0 and 6.5 if possible! Cheers and happy growing!

Bottom leaves yellowish - why? And can I top?On both of my plants (C99 & S.A.D.) the bottom leaves are turning yellowish and I can't figure out why. I'd also like to top them this week (above 3rd node), but I'm hesitant because of the leaves. Any advice on what they may be missing, and whether I should wait with topping?

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Too much light or PH imbalance?I dont know, something strange about the color, the spots on the leaves maybe? suggestions accepted. Maybe I need to add a fan ASAP, or let more air into the tent?
Dimmer is sset to 20% 25% , maybe I should give more light? or maybe less?
