First Indoor Grow 2.0

April 30 - Nothing special to report. Wondering if anyone would like to share their personal preferences for certain flowering care; 1) Should I defoil more to allow more air flow? Or does this look good for now? Worry about stripping the plants nutrients away from it. 2) Airflow directly on buds this early? Seems to be drying out the pistols which I don't really need right now. May 2 - Thanks for the help :) Have been very selectively picking a few fan leaves that majorly interfere. The rest left alone. Have been noticing a little bit of what "looks" like a rusty powder on all 3 of my plants but doesn't rub off. All around mid range on the plant, closer to top. I decided it was calcium deficiency and noticed a possible magnesium deficiency as well. Both of these having higher pH lockouts. Have been giving them 6.0-6.5 (usually always 6.25 pH). Maybe in coco coir this has been locking them out. Giving one day of 7.0, then 6.5 for a few and see what happens before changing diet. Thoughts? May 5 - Have checked for leaf septoria, thankfully doesn't seem like it. Have cut 1 leaf for better inspection. Continuing to add 6.5pH water, am also thinking if this doesn't do it, it may still be calcium deficiency; but may be due to me using coco coir and no cal/mag additive. Have added more airflow and lowered humidity in the grow room as well.
