lower leaves dying, spots on higher leaves.

Weedle1 · Nov 22, 2011

My plants are about 6 weeks into veg I'm switching them to 12/12 tomorrow. There in 1 gallon grow bags with FF ocean forest soil. There under a 400w MH air cooled at the moment. I've given them 2 feedings so far, the first one was about a week ago of 1/4 strength big bloom and cal mag, and then a couple days ago of 1/2 strength big bloom and cal mag and 1/4 strength of grow big.

The strain is kalichakra from mandala, temps have been at a steady 72-78.

Any help would be great!

Thats nute burn man. I have a similar thread I posted a week or so ago in the problems section you could read. My leaves looked exactly like yours. I even had the spots on the upper leaves. I just flushed and they were good after that. From now on I'm waiting for signs of deficiency before i feed.

I didn't notice the spotting on the upper leaves until after the thread so thats why you don't see me mention it.

Rule of thumb for flushing = 3 times the amount of water that the container will hold. If you have 3 gallon pots you would run 9 gallons of water through your medium. I only flush with twice the amount but everyone is different. Twice the amount worked for me but they were tiny containers.

I read your thread silusbotwin and it seems like most people agree that they were hungry and they weren't burnt? Idk, any other opinions?

If they were hungry instead of burned, they wouldn't have went back to rich lush green growth after they were flushed. They would have just kept on deteriorating. Just my opinion, take it or leave it, just hate to say I told you so after they're burned up. Take a look at the plants now. Mostly all green and healthy. Link in my sig.

I had the same thing happen to me...Fox Farm Ocean Forest hasn't treated me so well

I had those symptoms Before I had even fed them, so I'm almost positive it wasn't nute burn...I think you might be dealing with a PH issue. The PH of my water going in was around 6.5 and my runoff was like 5.0 (when the problems were happening) Now its up to 6.0 so I still have probs just not as bad. If I were you, I'd measure your runoff PH just to get a guestimate to what's going on in your soil before you decide to flush. Have you measured your runoff yet by chance?

That makes sense because my runoff ph was way low. Thats why I chocked it up as lockout deficiency/over-feeding. Damn I'm stoned man.
