Hey there growmie. Imo it does appear to be a little too much water. And yes plants do like a little chlorine now and then . And also you mentioned that you use R.O water. That being said you might want to check for purpling or violet color on the leaves stems and new branchlets because R.O water has virtually zero dissolved minerals . Calcium and magnesium are filtered out . Also watch out for little rust colored spots on leaves. Hope that helps friend and as always happy growing.
