the light is about 12-inches off the plants, and its obviously brighter right down the middle. should i move the light up to better distribute the light? my thinking right now is closer light=more intensity=denser buds. would the airier buds on the edges dramatically benefit if the light is moved up? (w/out affecting the already dense center buds)
If you look closely at the fan leaves in these closeup shots you can see a white powdery residue on the leaves. it feels like talcum powder and it covers all the leaves. (no smell to it) i dont think its a pest, but not sure what it is.
finally, now that im getting closer to the end, what do you recommend for the final flush? have read some contradicting theories here in IC and in books. ie, nutes all the way through the end, to 2-week plainwater. I noticed that in the past you do a plain water flush for a week or so, what the shortest time in plain water you would recommend? any other supplments you would add at that point?
