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

Heavy fast yellowingI flushed my plant because of too high ppm reading from run off and now she seems to be going all yellow. Is this normal for this stage of the grow (all trichomes still white and small buds) or is this a definite nutrients deficiency during flowering?4y ago

Magnesium deficiency?I think I may have an early deficiency of magnesium? I'm totally guessing here. Not much experience. Seems to slowly be getting more pronounced.
First water since transplant to FFOF was only pure RO. Thinking maybe I should added cal-mag?Week 3
