Looks like an Mg problem to me. http://boards.cannabis.com/attachments/plant-problems/281235d1325194867-brown-spots-some-twisted-leaves-some-tips-curled-down-phchart.jpg
it might be low mg i could see that so epsom salts??? i will make the nutes at 6.0 to get the runnoff to 5.8 any other ideas???
Sounds like a plan. I'd get the ph stationary (if you can) @ 5.8 for improvement, then go from there, and work on RH stability.
its been looking like this for a month. i have no idea why ph is 5.8 RH is 50-70% yet they look like they are drying out only 1 person has any input??
