Yikes... just went in there and realized my pH is at nearly eight (sunshine#4) this is way too high. I was using 100% r\o water for a while and the ph was always pretty much right on always, so I needed to check it less frequently.

I have been using around 25% tap water mixed with the r\o water, and have not been completely on the pH so they most likely have been receiving 8.0 pHed water for a few weeks now - yikes. It's tough to tell what the problem is because lock out\nutrient burn\heat stress all look fairly similar on the page I view for plant problems.

Obviously going to check every single day from now on, but now I think I have my answer that pH problems are bringing up some lock out?

I don't have an easy way to flush em all, and quite honestly most of em look good... not huge buds but I'm dealing w. a relatively small yielder and I've been told they add alot of their overall weight in the last 3 weeks. But perhaps I should flush the ones that have the yellow patterns on a few leaves. What ya guys think?
