Hey there HS. I just saw your post on the 600 and i was curious to see why your leaves are dying. Upon some catching up on your journal Im wondering if your temps are getting the best of the ladies. It also looks as though they have gotten a bit of nute burn. It happens, I have a strain that hates the reg diet for my room but the rest of the plants love it. It may be that you need to back off a bit with the nutes. For example FF Fox Farms has a nute schedule that i have found to be a bit hot at times. Matter of fact my BW is having a similar reaction only im 6 weeks 12/12.
Back to your temps HS. The leaves ar canoing up ward as they should but they def look hot. I am stoned and cant remember if your cooling your lights. They will really dye off quick if the temps are to high. Just tryin to help bud. You should still get some good weed from them ladies. Chin up bro.
Nice work rooting them clones. Seems youve got err down HS.
Peace 1BMM.
