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?
razzapiggy Reviewed by razzapiggy on . Purps Five weeks into 12.12 Here are a few pictures of my Purps plants five weeks into flowering. I am having a bit of confusiong as to weather the burning on several of them is from heat stress or nutrient burn. My temperatures are 76 degrees lights off, and sometimes as high as 87 lights on (87 is the temp around the floor where the lights are on, which leads me to believe my canopy could have been over 90 pretty easily. I had some problems with ventilation but got it worked out, and hope to see lower temps Rating: 5
