Drooping and Brown Leaves. Whats wrong?

I got 5 clones of this Strain of Purple Haze. They were all in very bad condition when I got them so I changed their soil and pots. The rest sprouted right back up and are doing great. I feed them once every 3 days. About 100-200ML I use the Finger and Weight test. Giving them very little nutes at this point because im out of Tiger bloom and only have Big Bloom dont want to use Big Bloom until flowering. They are 3 going on 4 weeks.
Not sure whats wrong here.
Should I give them the full dose of big bloom even tho they arent flowering? Is it possibly nute burn?
Its about 80-83 degrees in their room with an oscillating fan. They are on an 18-6 light schedual with a 400 watt HPS bulb.
Any help is great.

They look like they are burning. I would cut way, way back on nutrients and only give them Nitrogen based nutes.

Can I have a name of a brand to ask for at my hydro store?
Anything else youd suggest? Thanks man.

If you're wanting to stay with fox farm it's grow big. They could honestly probably just take water for now. I wouldn't feed them for like 2-3 weeks or so if it were me. Let their roots spread and get stable. They are going to be stunted for a good week or so probably. Also, tiger bloom is VERY hot stuff from what I remember so its easy to burn them with it. Don't use that right now at all.

So should I water them straight PHed water for the next week then back to grow big at regular strength?

I wouldn't do it at regular strength. If you feed them at say 1/3 strength they are still going to grow they just might be a little less green or something. If you feed them too much they are either going to stop growing, and show signs like they are above, or just die. Feeding less is way way way better. Then you can taper it up from there. From experience more nutrients doesn't equal more yield or anything like that. Just keep them healthy.

Water them with just PHd water for around 10 days, and then feed them around 1/3 strength nutrients. I'm a hydro guy, but the concepts are all pretty much the same, just different mediums.

Will do thanks man.
