This has been going on for a couple weeks now and I think its some kind of mold or mildew problem. Theres no bugs of any kind. Plants are Purple Trainwreck about 4 weeks into veg.

The leaves seem to be disintegrating from the stem end on the top and middle sets of leaves. I trimmed all the affected leaves off and tried a sulfur burner but in a week after it was back again.

Temp is from 68 to 75 deg, humidity is high at around 60%, ph around 6.5 to 7.0, pretty good air circulation with a wall fan and a exhaust fan for the lights, screened inlet from the floor with a hepa filter. Should I try a fungicide spray or what , any suggestions? is it too late?!!

Leaves were fine for about a week and now see pictures?

All advice appreciated!! Thanks
