Guess that deficiency!

1100 watt from wall worth of grow lights. I just started introducing uvb 4 days ago but only for 15 mins up to 30 now.

6.3 ph water. However the runoff from the potting soil was 5.6 and the runoff from organic was 6.7. I raised the potting to 6.2 ish when I flushed. Runoff ppm was 2200 at first

Run off on soils doesn't matter. Only worry about what goes in.

Do you water to runoff every time?

Its fox farms nutes. Which means there is a solid possibility of salt build up at the roots. That can cause many issues.

Ppfd 1200-1600 across whole scrog

I water till about 8 oz maybe runs out.

on next grow should I switch to organic or another kind?

I wonder if the night temp for 3 days hurt it? Got to 69 at my thermometer. The 2 stunted plants are under the register I put in. It’s closed now. If it was weather related is there anything I can do?the other 3 plants are doing pretty well

my guess is overwatering and nute burn. Your just putting too much thoughts into your grow

Thanks for the advice. I prob do overthink things. Seeing the plants hurting drives me crazy! Just got my card, first grow.
