These girls are Dutch passion auto blueberry and a nirvana blue mystic. Grown in pearlite using Dutch master gold one range. The ph is maintained between 5.2 and 6. They are fed daily at ec ppm 800. Flushed weekly. Please help fix my girls.Attachment 290482Attachment 290483
it looks a little like a ph related lock out or nute burn.
Why do you say that? Could you give me more detail please? What would you suggest the ppm range should be?
I know it's not lock out at I change the nutes daily and from what I can tell 800 ec is low.
wait 800 ec? thats not low if its electrical conductivity thats a measure of salt and metals. 800ppm is reasonable for nutes.
look at the leaf burn pattern it looks just like this one and it was caused by low ph
Attachment 290484
if your ec is really at 800 thats a huge problem. if its your ppm thats ok. your ph sounds normal for your type of grow i guess. have you changed anything? added anything etc? while we're at it fill this out and see if we can get a few more opinions.

looks like algae forming in there, not sure if that has anything to do with it but im not sure its a good thing. maybe it affects the perlite ph. try grabbing a hand full see if you can check its ph. everything seems mostly normal but those pics look like ph issues of some kind. need weezard or low_rdr or one of those guys. theyll have a better idea.
Thanks.
When the problem started a few weeks ago I was just leaving them in the solution way too long like all day. I've reduced the feeding time to 6 hours a day. I also increased one plants nutes and reduced the others but they both only got worse. About 2 weeks ago I reduced the nutes. It's only getting worse. Could it be build up? The ph rises so much that I start at 5.2 then at the end of feeding its up to about 6.0. How fast should recovery be?
