Iron lockout?

Soil: Promix BX
Lights: Mars Hydro TS1000 x 2 Mars Hydro TS 600 x1
Feed:Green planet duel fuel + additives. Cal mag, silica.

I transplanted (and probably overwatered) this plant in to a 20 gallon two weeks or so ago. Flushed it a week ago because I noticed my runoff ph was a tad low and yellowing was occurring at 5.3. I flushed until it ran clear, tested 6.5 PH reapplied nutes at 6.2 which i beleive 6.5 PH locks out iron in soilless mixes.

(I've dropped the ph back down to 5.8 on my other plants as they have dried up. They seem to be recovering with half strength nutes.

Anyways the pots are taking forever to dry even though it seems quite rooted. I put a fan over it to try n help it dry out. It's helped a bit. But this soil just retains so much water didn't plan for this.


Any ideas how to get this baby greened up? As I cant really water for a couple more days until she's dried out.

It looks totally fine to me, new growth often is light colored, I don't think you have an iron def.
I hope so. Am I just crazy? please tell me i am lol.


Any advice on the whole taking forever to dry thing? I've been using towels here and there to wick moisture out.
