Drooping leaves and extra purple stems.

Clones were cut 4/23. Transplanted to 1 gal pots approximately 5/7. Currently led is at 200 watts approx 12 inches above the tallest one. When they were transplanted into the coco they started at 80 watts approx 4 inches above the canopy and were doing good. A couple days ago they were drooping and I moved the light up and they perkd up within a cpl hours. They started drooping again this morning so I steady been moving the light up all day and it doesn't seem to be fixing the issue. I use ro water with botanicare kind nutes and was feeding at 2/3rd strength at 1st week recommended feeding schedule. Watering every 36 hours. Thought it may have been nute burn so dropped down to 1/3rd strength and didnt fix the issue. My ro filter is getting clogged so I wonder if this could affect them. When I checked it a few weeks ago water was coming out at 50ppm from 0 when I first used it. Ppm may be more now cuz it got clogged to the point where barely any water was coming out. Switching to tap in the morning until I get a replacement. If it was soil I would think they were being watered to often but I was told to never let the coco dry out. Heat has been a lil excessive. Mid 80s max. 70 min. Humidity around 60-70%. Any ideas what my issue/s may be???? Thx in advance guys.

Do you use any pH buffers to help you out? New growers don't realize buffers added to soil gets neutralized faster than you can finish your grow. I always have bags of dolomite to top dress periodically and if I see pH down symptoms.
I have never seen with mine own eyes an alkaline soil problem. Most what us growers use is acidifier ferts, organic or conventional, shoot even our molasses will drop pH a full point or two. And when low pH causes deficiency you can bet your roll cal and mag are too.
