Thanks for helping.

My first grow hit 3 weeks today. Hazy Cush S1 feminized photoperiod.

I am seeing significant inconsistencies in my plants.  One is about where I expected and the others are lagging behind with one being really slow.  Growing with full AC infinity 4X4 kit. PHing water to 6.5. Using fox farm ocean soil and I added 10% gaia green worm castings and a little 4-4-4 to the soil.

I am follow manufacturer recommended light distances and am currently at 80% power.  Watering only when soil dries, and the big plant is watered about once every 2-3 days with the smaller plants taking 4-6 days to need more water.

I am also seeing some intermittent brown spots on my leaves and they seem warped in ways.

environment is locked at 78-80 degrees F and 45% humidity during the day. 2 fans going.  Running 18/6 light schedule. No sign of pests.

my question is what might have caused this growth inconsistency and the brown spots and I guess what I need to adjust. I am prepared to dump this grow and start with new seeds (blueberry muffin from Humboldt) if necessary as I don’t want to keep pushing forward if It’s unreasonable.
