Hello!! I'm needing some opinions here. I've been growing my afghani in dwc for about 2 1/2 months now. Been having issues with ph and keeping the res temps low enough. Just wondering if the curling leaves on my plant is due to the too-high res temps?? The fan leaves have randomly been canoeing for quite some time now. Some of them look perfectly fine and some look like the photos attached. But now some of the new growth is becoming affected, curling under and looking twisted almost. She's currently under a 600w metal halide for 18/6. Giving her about 500ppm total of flora series, cal mag, hydroguard. Also wondering if this is too little of an amount of food for her size?? Going to switch her to 12/12 soon and wanting to fix what I can before then, if possible. Any input would be great, and if more info is needed let me know. Thank you in advance!!!!
