I am gonna go with your soil ph is likely riding the line. Test what ph is of run off to see what substrate is at. Then if need to adjust add proper ph solution till desired run off ph. Lock out from ph can cause all kinda issues. Good luck and happy growing 🌲🌲🌲👊

New growth and top leaves have some discoloration. Could it be light related, or maybe a zinc deficiency?She has been flowering for about a week now and showing some pale spots. At the start of flower I turned the light up from 200w to 300w. Light is currently at about 20" from the canopy. Plants seem healthy otherwise, should I be concerned?

What could be causing this?I'm experiencing yellowing, browning and crisping on some leaves, but only on the main colas so far.
I have checked the PH in and out. In has always been perfect, but the PH of the run-off was 5.8 so I'm flushing to rule out nute lockout.
Anything else it could be??

Yellow Burned Bud Leaves. Purple Calyxes. Red Stigmas. Stunted?As u go from top of canopy to bottom, the leaves get darker green and less burn. Lamp is at top of 3ft tent, 10 inch above canopy. Feed is at 1.3EC/6.1ph. Runoff EC climbs, then I FloraKleen flush about once a week. So is it just light burn? What you see? Is she stunted? Thx.

I have tried to figure out what this could be without much luck... it seems that my leaves are having a slightly yellow tint to them under the grow light. Under normal light it seems ok, what could this be? Overwatering I am guessing but not sure..
Any help would be appreciatedWeek 2
