Is this the same problem you were having before?
http://rollitup.org/t/bad-problem-here.908016/

We need all the details of your grow such as the type of fans you are using, when they are running and are you exchanging air with outside at all? Also what is the exact type of soil, nutrients, additives and etc. We need to know your temps, humidity, light type and distance, whether you are spraying the leaves, what the strain is if known, and as much info as you can give us. Watering habits are also helpful along with anything else you can think of. Do this and you will get some great answers but in lieu of listing your details you will be getting guesses. Although RM3 probably already answered this we should take a closer look to make sure.

This is the same set up that I successfully used in the past. This plant had the same problem early on but seemed to be fixed when I flushed it but for some reason just came back.

What was ph of water you flushed with? You could have lowered ph during flush which would allow plant to uptake nutrition now your ph has gone up again relocking nutrition out and showing ph Issue.

What nutes? List everything you use!
How much?
How often?
WHAT water?
WHAT SOIL?

Do you pH the feed? What to?

Fuck the flush! Looks like that may have done more harm then good in the long run!

Don't bother pHing any run off! That's not the soil pH or near it either!

Looks to be a a Ca/Mg def with possible other Micro nute defs and it could be pH related.

Never said to flush he said he flushed It prior and issue went away. I asked ph of water going in not runoff. He said ph is 7.5 never mentioned runoff.

I mentioned it for him. When you water the pH will drop and rise back up as it dries out. Flushing large amounts through you soil will keep the pH out of optimal range too long and promote longer term pH problems..

I mentioned run off for him too....he may get the idea to try that - don't!

Sorry, I get focused on the goal

Using Edna's Best Potting soil. Just flushed with PHd water until runoff was 6 or so. 3 gallon bucket. 2700k cfl bulbs. I have a good feeling it is from water that was too alkaline (runoff was 7+) now 6.

Sorry i may have read it wrong ( very stoned) seemed like you were saying I wanted him to flush. Im very much anti flush. My wording could have maybe been better

You dont wanna check ph of runoff that will not be accurate at all.

Just a couple of leaves yelowing? dont worry about it, it is bound to happen. If the plant on the whole looks healthy and the new growth is vigourous and a normal colour just continue what you´re doing and dont over do it with the nutes. Although nire information is needed for an accurate diagnosis. Answering DR.Whos questions would be helpful
