In the past week a couple plants seemed to have gone dead. They are all the same clone but this plant and less so another one or two seemed to have become sick and I can't seem to figure out why when all the other plants are fine. You can see the plant directly before it is perfectly fine.

I removed the tomato cage and the sick plant just rocked over, not held tight. Did this individual plant experience root rot?

Any thoughts?

What do the roots look like? Where inline is it happening? I see the 3 in the front row right, but are they the same down the line in that row? Any in the back row effected?

That's the thing, roots are white and look healthy. Happening in plants 3 (shown in picture), 4, 5 down the line in a row of 8. Plants before and after are perfectly fine.

speculating entirely but, could have root problems, maybe stem rot. what size do you transplant into the UC at?
They were about 10" I believe when I transferred them. Would high water level cause stem rot?

Have you checked the flow to those pots? How about you're DO levels? L
 
How would I go about checking DO levels? I'd assume they'd be in a good range using the Under Current, it should be designed to be in range right?
 
Ok after doing some deduction I've come to the conclusion it is stem rot. The reason the plants in the middle are sick and not the outside is because all the clones weren't the same size and I had put the larger ones towards the outside of the system so the ones in the middle could get more light to catch up.

Water levels are lowered after just noticing the water level blog post from a month ago.

Now how can I heal the stem rot?

See that lil white box at the yop of the page? Thats the search bar... Type in lollipopping..
Get used to searching, and reading because you will need fundamentals to discuss growing. Remember these guys want to work with you, not for you....

But i give you your first thread to read on me..

I've never heard of anyone referring to trimming the nodes not getting light to lollipopping. I just always thought it was a normal practice. Thanks.
trimming fasn leaves to get more light to the nodes id=s not lollip[opping.
Lollipopping is removing the very bottom growth so that it has better air flow AND so that the plant can focus its energy on the tops, where the buds grow. IT is used to increase the size of you colas...

I know you prob havent read any of my threads, but i would never give you bad advice. Some ppl will come along and vouch for me and will reiterate what i have just stated.
Back to the original question, i would just spray with diluted h202, and watch closely...
