Need a Little Help with Sick Plants!

This is my first grow and I have two plants that are having some troubles. 1 i think is caused because it received some pretty bad root damage when transplanted (the worse one is the root damaged pic 2). But the other one i dont know whats wrong with it. They are almost 4 weeks old. In fox farm OF. Temp 75-85. Humidity is 35-50%. I just switched them from MH to HPS and 12/12 lighting. Hoping they both just turn out to be male because they don't look like they are getting better anytime soon.
The other plants are fine except for the tips of the leaves.. they are on just water right now. Sorry the pictures aren't in order

Any help or suggestions are welcome.

They might be having problems adjusting to the light and temp.
How long did you veg.? Those small pots cant produce that big of a bud.Can they?

How many times have used this method has this worked for you in the past?

I have no clue about the bud.. first grow. Transplanted them from plastic cups to 1 gallon buckets. Have 5 gallon buckets but don't think i'll have the room if too many are female. Veg'd for almost 4 weeks. Just switched the light today. Have 13 total and can't veg these longer for them to get better.

Out of 13 this two are the only ones that have any problems so i doubt it could be the method if the rest are fine. 1 of the damaged plants (worse one) is my fault.

Check you're PH If it is ok. Try to flush I always try that before going to extreme measures.Let me know how it goes.

pH is okay.. pH all water i give them. I will flush these two and see if they start to get better. + rep for help

Looks ok but seems to lacking N ,maybe feed with veg nutes now.
