Hi guys, I'm having problems with some clones I've recently acquired. There real small, they were just starting to get roots outside of there rockwell cubes and were put into solo cups with coco just before I got them. I didn't realize they were going to be so small, so the only light I had was a 600/400/250 watt hps. I gave them some half strength thrive alive and distilled water and put them under the light at 250w maybe 30" away (the guy I got them from had them under cfls). They started to curl up and yellow at the leaf tips after a day or two. I tried some half strength big bloom (a quarter of what the schedule says for clones) after watering them once with strait water but it didn't seem to help at all. Since then I have given them only distilled water. Two weeks later they are still alive, but have not shown any growth or development. The biggest leaf of each of them started to yellow (looked like n def) after a few days and has been slowly getting worse. conditions have been pretty good, humidity got a little low a couple times at 45% but its usually 50% 70-74f. Recently two of them got moderately dry (no where near bone dry) and started drooping a little (left two in the pic).
I decided the light was probably the culprit and bought a 125w cfl off amazon for $40 (wish I would have just done this to start with), but now I'm debated whether I should switch the light or not. If the plants have already adjusted to the light, will switching to cfl actually stress them more? I have heard of people putting young/sick plants under cfl for a few days to rehabilitate them, but does this really work? So should I try the cfl or just stick with the hps at this point? Also, should I stick with strait water or try some low strength big bloom or thrive alive again? As you can see in the pic, they are on there last legs, so any help is appreciated.
