Deadhead OG First Grow in longggg time

Day 15 - 9/12 - noticed some rusty looking spots on one Lower leaf Of Plant in one gal. Will monitor. Day 16 - 9/13 - looks like rust spots are nut burn which makes sense. Gave a small plan a lot of nuts last feed. Will flush and slow feeding Day 17 - 9/14 - water .25 gal per, ph 6.75 Day 18 - 9/15 - Day 19 - 9/16 - 2 plants are stretching. I messed up topping the shorty that looked great. She’s coming back but first nodes leaves will be cut. Looks like they’re drinking more as soil is drier while temp has dropped a degree. Day 20 - 9/17 - Fed big bloom 30ml/g and grow big 15 ml/g .25 gal per. Ph 6.75. Couple plants had a minor droop so they def need water. Day 21 - 9/18 - One week before flip to 12/12. Plants are filling out nicely since topping a week ago. Defoliated bottom three nodes fan leaves of 6 plants plus one gal plant. The canopy is more pronounced while allowing more air flow below. Fimmed one gal plant.
