First time ever grow. Please be gentle.

Day 36 Both plants seem to be taking to LST fairly well. Have switched on both veg and bloom lights now. Considering doing some trimming of Plant 2 as it is small and compact and I believe could use more light to the lower section. Day 38 Experienced some major drooping over the past two days, didn’t take pics but wish I would have. Major issue seemed to be that when my reserve of melted snow ran out and I switched to tap water (which I allowed to dechlorinate) I didn’t check the PH, which I later found out was between 7.5-8. I corrected my water supply by bringing the PH down to 6.5 using white vinegar. Day 41 After battling PH issues all week I think we are finally in an upward trend. I have tested and retested all of my water jugs are sitting between 6.2-6.5, so hopefully over the next few days the negative affects subside.
