Additional information:

Just noticed the problem about 3 days ago.

Strains are Nirvana Pure Power Plant and Critically Smashed. They were started late and grown outside, so the soil also was outside. Have already had a round with spider mites that I knocked down with neem oil.

Grow room is a DR80 tent (2.75'x2.75'x5.25') set in a closet; barely fits inside. Passive airflow wasn't cutting it (temps above 80 F) so I added the duct booster fan two days ago, temps run about 2 degrees F above ambient now. I can't raise humidity at all even though I put a room humidifier in the tent. Probably too much air flow.

I just ran the runoff pH tonight - I thought it was much lower, so maybe that's my anser, and I need to flush these girls really good with pH adjusted water. (?) Thanks for any comments or suggestions.

quick glance here; get ph down to 6.5, dont overwater, you'll need some calmag with that bottle water l8trs

Thanks veggii. Hope you get to feeling better.

Never mind - I rediscovered my library, and my very old notes.
