So I'm a very new gardener, I've been vegging for about a month. These plants are just for mothers, I plan on cloning them to start my dwc grow. The problem is i have these curling leaves and not sure what's going on if any of you have some input let me know please what can I do to stop these moms from curling at the fan leaves?

Tempature is around 75-80, humidity is 55% ATM not very humid. I also noticed that some of the stems are reddish/purple could this be toxicity of some sorts?

Stem color indicates stress. Leaf curl like that is indicative of lack of oxygen at the root level which perhaps causing the stress.
 
Drop temps 10 degrees and you'll get more dissolved oxygen. "As water temperature rises, oxygen solubility decreases. On a cool summer night, a lake's temperature might be 60° F. At 100% air saturation, this lake's dissolved oxygen levels would be at 9.66 mg/L. When the sun rises and warms up the lake to 70° F, 100% air saturation should equate to 8.68 mg/L DO ³." My worst grow ever was when my AC unit started leaking refrigerant and temps rose to 85 in the room. Water needs to be around 65-70 for best results, PH around 5.7, and PPM 1,000+ with fresh nute mix. Dropping temps below 70 gets rid of so many problems.
 
The first pic looks healthy to me. Keep the temp within 10 degrees and you're fine. There is always gonna be some kind of temp fluctuation.
