Both plants are stretching up.
SLH is showing nutrient deficiency of cal - mag and maybe nitrogen.
Made a foliar spray comprised of:
1/8 tsp powdered silica
1/8 tsp Kelp it Real
2.5ml of Cal-Mag (yes it’s synthetic but I am unaware of an organic liquid source of cal-mag)
Spray leaves before lights off and soil daily .
I can completely understand the 3,5L / day. My plants have a similar size at the moment and I also worry that they drink too much. I put 3 liters almost everyday now. They are sucking it up like heat a snowflake.
@DubistderChamp, I actually use AC infinity’s 1 gallon water bases. And wick lines to deliver water to the bottom 2/3 of the soil. So right now I only gotta fill up the bases every 2-3 days. But yea they are thirsty!
Thanks for commenting and happy growing! :)
