Hey Fan Man - What's the RH now days? I am researching high RH and leaf curl
. After lots of checking
, I don't see this curl as a over N issue. The leaves look fine, other then the curl. Do you have any drying up or falling off? NOPE, well from my understanding over N causes more issues then just leaf curl. But all that is happeining is leaf curl? I think there is more to this story.
Just gotta figure it out.
Let's compare notes. I have this same issue. I have plenty of light. I dropped temps for a week to stop fert from OC, had temps at 60 at night, and 72 max lights on. Changed to straight PH'd water, so all good for a recovery... but- no reduction of leaf curl...
One thing I didn't change, my RH. RH was still 55 - 65 most of the time, and maxing out at 75%. I just started a test, and will not have good results for at least 4-5 days, but I WILL have my RH at 40-50 steady. I pulled it down to 47 - 59 last night, I did have a spike of 64, but that was me screwing around that caused that.
