I was wondering if anyone could help me out. First time growing in soil. I am using FF Sea forest blend and the seedlings are currently in 4? peat pots. The oldest ones are about 21 days, the youngest 14 or so. pH is about 6.8 for both soil and my tap water. I water sparingly once a day, when top inch goes totally dry. Once, I used about half the recommended dose of Neptune??s harvest for seedlings, but have since stopped after some forum reading. The plants are under a 600w HPS approx. 30 inch away, doing 18/6 and are well-ventilated, with a fan blowing on low at all times. Temp seems to be about normal, somewhere in between 70-75 degrees, and dark period happens during the day when temps are similar, but I was baffled to find three of them dried to death this morning. Must have happened when I was sleeping, others are drooping slightly and showing a slight yellow coloration, and one looks challenged (leaves corkscrewing in strange ways?) Did the three just not get enough water? Or too much? I tried to revive them today, but only one has responded to more water. I would like to prevent anymore murdering of my babies. Any help would be appreciated, thanks in advance.
The first two pics are the ones that look healthy other than a little droopiness and yellowing (very slight), the third one is the "challenged" plant, and the last one is one of the ones I obviously killed.
