This is the 3rd seedling I have tried.
It looks possibly burnt, I didn't properly pH adjust this attempt I just added some pH down, I know thats absolutely counterintuitive.
Anyhow, I have a rockwool that is sitting soaking in solution I tested with a liquid test to just below 6ph probably 5.7-5.8
I was planning on adding 3% h2o2 and getting a scarified seed prepped in a 24hr soak.
I assume this latest iteration of failures is going to die but curious if anybody can diagnose what is actually happening.
I have it under a mixed spectrum multidiode with UV and IR and mixed visible spectrum light, very high par, 50w led chip about 12" away.
I tds tested the water, showed slightly over 700 TDS, probably too much fert still for the seedling.
Could be a lot of things wrong.
Next time will only add seaweed supplement at 1:500 until the seedling has several good leaves and then straight to dwc.
