These are 4 week old plants that just rapidely developed this problem. Everything was going good until this. The bottom leaves are effected. I'm running a DWC with an ultrasonic fogger that has been on 24/7. My PPM are about 525. PH 6.1. I'm using organic Botanicare Pro grow. Any ideas? How do I fix?

looks like nute burn. Use pure water for the next couple feedings. Watch for the burn to stop spreading upwards. Plants dont need much fert in soil.

for a DWC at 4 weeks nutes sound a little high PH too. Lower nutes to about 400-450ppm and PH between 5.6-6 looks like mine does, either PH fluctuation or an MN Defficiency.GROWFAQ
