All four plants are looking unhealthy. I have identified this as an issue with the water pH. Each plant was around 8.0 so I flushed each plant with PHed water to get the soil into the 6.5-7.0 range.
All 6 of the seeds died. I believe that I got the growing medium too wet and the seeds proceeded to rot.
Ah man sorry to hear about your seeds. Your nutes are out of this world high (I'm using about 1-1.5ml/l when feeding). You might be locked out. What kind of soil are you using? I wouldn't put any more stress on those plants - as in don't top, don't lst at least until they're back on track.
I'd lay off all nutes except for cal-mag and maybe 1ml/l of the micro grow bloom.
What are you thinking about popping in soil next since those autos are gone?
