First grow - Auto Hindu Kush

Watered once 01/19/21 (Day 23) with 6.5ph water, no added nutrients yet. Kept adjusting my LST every couple of days to try and get as much surface area exposed to the light as I can (first time so having some trouble haha). One or two of the very lowest leaves look wilted and dying probably because they are underneath everything and not getting enough light. Around day 28 plants started to show some signs of deficiencies starting, gave them their first feed of the grow on day 29. 3Tbs each of Gaia Green 4-4-4 and 2-8-4 per plant and watered. Actually as I'm typing this I just realized I think I forgot to ph my water -_- Hope that won't cause issues. If I remember correctly I believe my tap water comes in around 7.4ph
