yellowish leaves? PICTURES

I have a small ebb n flow op going on right now with only 4 plants. This weekend marks the beginning of the plants 3rd week in my set up. The two trainwrecks i have are growing rapidly (i'd say one is 9 inches tall while the other one looks closer to , and the two GDP's i have are growing slowly but surely.

I am a new grower so bare with me if i dont catch on right away.

Heres me two questions:

1) The leaves on the train wrecks are looking like they are starting to fold "taco style" (for lack of a better phrase). Does this mean over watering or something else by any chance?

2) As you can see, the leaves on the train wrecks also look skinny, and beginning to look yellow. Is this a sign of anything as well?

In the pictures, the two plants on the left are the train wrecks while you can see the smaller GDP's behind them. Also, all the close ups are from the trainwrecks. Let me know if you guys want more pictures of either plant. i will keep you updated.

= 8. sorry

At the moment they will be fine, if IMHO, you make a few minor adjustments....

1. The HO T5-is making a little too much heat for them....see the bronzing at the very tip of the plants in the second pic and the curl is probably just heat stress/light saturation......
Is thatt a 4'-8 Bulb HO T5 Floro (400watts) ??....if so raise it up or if it has 2 switches -then turn off half the light.

You cannot put the HO Floros as close as CFLs or regular shop light floros

2.They all look a little overwatered...make sure that rubbermaid is draining thouroughly and the roots aren't sitting in water.....the lighter green plant looks a little deficient but due to the shared hydroton set-up it can't be quarantined to pin-point the prob......it could also be a little weaker than the others....maybe its just gonna struggle.....everybody deals with some weaklings in their op......

Ph?
TDS?
Temps?
RH?

all these would help my ability to accurately diagnose the probs.

Hope this helps for now-
