First ever grow

I don't know what it was that caused my plants to do this I just watered my plants with ph water and it seems like the plants are doing fine it could either be not enough water or to many nutrients. I am using ocean forest and that might be the cause.

This also looks alot like chronic underwatering. I'm curious if they have had a good drink near the base of stem? I looked through your diary and your pictures look very dry.. Also you really don't need alot of recharge.

@jpeero is 100% correct. Upon further review, it does look like an N deficiency. Thay said, it could be an N deficiency either way; too much or too little in your medium. I'll defer on which to smarter growers, lol.
