    Hey RIU,

    What causes paper like leaves and slight cupping, also appears that newer leaves have been developing slower, smaller, and skinnier.

    5 weeks veg, will be transfering to flower upon recovery. Some ladies are rootbound but roots look healthy.

    Problems appeared after adjusting light cycle from 24/0 to 18/6. Box was probably fairly cold, mid 40's for two nights. Also shifted water cycle to water every 3 1/2 hours instead of 4 1/2. Decreased nutes during this time also.

    System: (4) 600w MH Air-cooled, flood and drain w/Rockwool, intake and exhaust
    ph @ 5.5 increases over 24 hours to 6.5ish.
    Nutes at 1.2ec

    Thanks :peace:
