Any advice appreciated.
Plants are at 14 days, 3 BB Auto seeds water germination 100% success, one plant (with the temp gauge in pic) sprouted with light green and contorted leaves. Just gave 2nd full watering and plant closest pic started getting little brown spots and the light green, contorted leaves started getting brown spots that have increased in size. The 3rd plant on back left looks pretty good to me.
My theory is that I have over watered? The pH prior to watering is 6.0, then runoff is 5.0 on all 3 plants.
Should I just let the last watering dry out?
Maybe add Cal/Mag Plus at next watering and go higher with pH?
