Droopy Yellow Leaves

- Plants are 1 month old
- Just switched from Flouresant to HPS a couple days ago
- They have gotten distilled water pretty much the whole time with little or
no fertilizer
- The HPS bulb is 250W and it's about 30 inches above the plants

They were doing great under Flouresant and the past few days they've looked like this:

Whats your soil ph and runoff? What nutes did you feed them?

Exactly how much did you give em???

The PH hasn't been checked on anything.

It's scott's soil, and some agro fertilizer.

Check the PH, Transplant into seperate pots, and also how is the temp doing? The HPS seems like it would be far enough away but you never know. So the soil your using already has nutes in it correct? you havent been giving them nutes on top of that? just straight water?

The pots are filled with the Scott's soil recommended in the First Timers Grow Guide

should there be a different soil in the pot it's moved to?

You shouldn't have fed them at all yet and they may be getting heat stressed from tin foil induced hot spots.
I can see from the pic that you have the most shiny side of the foil facing out into your grow.
You want the dulled side facing out so as to minimize hot spots.

In all reality tin foil does a poor job and can burn your plants.
And the final thing that could be happening is that your strongest plants roots may be attempting to kill the other plants as you have 3 in a pot and they know they don't have enough room and its survival of the fittest as far as weed is concerned anyway.

can they still be separated? Or are the roots too interconnected now?

thanks for everyones help btw!

the roots are def interconnected... you can still seperate them but i would do that asap it you are going to... if you dont one or two plants will die for sure and the overall health of all the plants will suffer due to competition... seperate them give the best looking girl the most space (try to hurt her roots least... cause she looks the best) the others should go into their own pots with plenty (not to much) water... they will have some transplant shock for sure but its better to do it now and see what makes it than doing it later, having to kill plants, or having three weak outcompeted plants
