To be honest, I’m not sure about the flush. What exactly are you flushing? Seems like flushing seedlings might create another problem (overwatering?). If it were my seedlings I might consider getting them out of that soil and reintroduce them to it once they’ve grown/recovered a bit and the soil has had a chance to cook. I’d likely end up killing them all too….so there’s that. Your instincts have been working well for you, trust them! Sorry I couldn’t give you a solution, I’m still learning shit.Thank you, lady! <3 I'm having a blast. Oh...colder temps in the flower room....good idea. That settles it: two rooms. One thing I do like about soil is being able to move plants.
Do you think a flush was the right way to go? I'll get a reading on the runoff in a bit...the man's still asleep and my meters are in the bedroom tent.
