Week 3 fade, lockout or hungry?

Docta Haze · Feb 21, 2020

Hey all I could use some help with one of my plants.

5gal living soil, 3x3 w/ 600w hps @22", temp 62-80f, humidity 40-55%, water w/ RO recharge, mammoth p, aerated teas, and occasional kelp meal.

I believe I added too much phosphorus, and I'm concerned this is a phosphorus lockout issue. I'm not sure what to make of it.

Thank you for any ideas, comments, and help!

Do you know your EC/PPM reading. If it's 2.8+ you need to flush them through as your plants could be suffering from nutrient burn/ lockout if that helps

Hey thank you for the idea. I've been reading runoff ppms to be between 500-900. I will water with low ppms usually 200-300 (living soil).

I actually thought she might be underfed and fading early, so I fed her yesterday. Gave her a topdress of ewc, and watered 1gal of RO with 1/2Tbs of guano, 1/2 tsp of Recharge, and 1/2 tsp of fox farm lush 6-4-4 (~850ppm).
