Ok so here's my rhino Ryder in coco, she was being fed 2ml per liter of AN base nutes and 2ml per liter of big bud. I have 3 going now and this one is really the only one showing problems... ph was off showing Cal lockout at 5.0 on Tuesday so I talked to @The Elvis and we flushed her and got her ph to 5.8 well I checked it again yesterday and it went back down to 4.1 ... so another 5 gal of 8.0 water was ran through her and she is now holding steady ph of 6.0-6.2 but the Def looks worse...

Looks like cal/mag def,especially if it's mostly on the upper leaves.If your using led's this happens more easily than with other lights. What type of lights and how far from plants are they?

yes it is pretty serious bro. right in the important stage of flower too... yes me and elvis came up with the idea of AN revive via Foliar for the past 2 days while the lock out.. these pics were from yesterday

yea def them and ive had trouble with cal def in early to early mid flower before and thought i had it figured out... how long does the buffering of coco last? ive used this coco for 2 previous runs and now this one. im using mars reflector series... she is under the 192 right now and at 12" away i have the 192 the whole way up unless i would take the steel cables off and jerry rig it.. temps are 78 and R is abut 58

i forgot to mention that this all happened while i was away for 2 days and the drip system res ran dry. maybe this has somethig to do with it? maybe getting too concentrated of feed?

This looks all so familiar. I have the exact same thing on my HBSS's. It all started after I left for a couple days. I also use AN. PH was low 5's. I flushed and gave 1/4 strength nutes and she seems to be pulling through.
Wish I could help. Just thought I'd let you know, you're not alone, for what it's worth. Good luck Trip.
