Problem with Plant. Need help with diagnosis

[Eatbatterys]

Hello everybody. First time posting here. This is my second grow. Growing two indicas in 5 gallon DWC buckets in a 4x2x5 grow tent with an 8 tube t5 cfl fixture.

I switched my plants into flower about 8 days ago on a 12/12 schedule. Since the problem started, I've stopped giving nutrients until I figure out what the problem is.

About a week ago I noticed the tips of some of the leaves were going brown. I figured this might be the early signs of nute burn. When I stopped giving nutrients, I noticed that the leaves started going yellow with green veins still showing on some of the newer leaves.

Anybody have any idea what might be going on and how to fix them?

Iron Deficiency, would bet money on it. Check your PH, if its over 6.0 you can be very sure its an iron diff.

That was my initial thought as well. I just checked the pH again and it's at about 5.5

I don't know, maybe someone else in the hyro threads can help.

I'm going to flush the system and see if that helps. Because if it's not an iron deficiency, then I have no idea what's wrong with them.

I feel the same, if its not iron, then I don't have a clue man. Sorry I couldn't be more help.

No worries man. You've definitely helped. Even if it wasn't new information to me, confirming my suspicions definitely ties it down to being an iron deficiency versus the variety of other conditions it could have. I think flushing the DWC out should help quite a bit. Thank you again for your input!

Just give it a little kelp. That would cover any deficiency possible.
