Twisted new growth

Hi guys,

Helping out a friend with her medicinal grow. The recently (1 month approx) sprouted seedlings are showing some twisted growth. Parameters( ph/ec/rv/temp) are all in check. Although ph sometimes drops down. This is a hydro dripsystem. when I look it up online. I get either broadmites or root problems.

What do you guys think?

Without knowing more; ph probably too low, and tops too close to light (frying new growth). But that's without having a lot more info.
