Need some help 6th week of flower

Gorilla glue auto grown in soil in week 6 ish of flower and the leaves are yellowing and becoming crispy by the day . I feed advanced nutes GMB +additives from them . Ph is 6.4-6.6 on the run out . Been feeding one a week full strength until about two weeks ago when noticed burnt edges . What can I do to save this girl ? Lots of white pistols as you can see .I’m just worried she will yellow and die before she gets to rippin up. Thanks and happy growing.

Lockout and/or nutrient burn is a pretty common issue when you feed AN at full strength, in soil, IMHO. I would flush the pots until the run-off PPM is in an acceptable range and then feed them 1/2 the recommended dose.

The flush- how much water should run out the bottom? And the ph I keep at 6.5?

The flush - how much water has to run out the bottom and the ph stayes the same when flushing at 6.5 . Ppm meter is coming tomorrow .

Yes, I usually pH my water to 6.5, and you just keep flushing until the PPM in the runoff gets within acceptable range. If it is really bad a 5 gal pot can easily take 5-10 gallons of water to flush all the excess salts out.

Wow I’ve put 3 litres already and no run off yet 4th started to come out a bit . Ok I don’t have a ppm meter right now is there any way to check without it? Thanks

Ph tester liquid is awesome, i use it makes it hella easy to dial in

It's impossible to figure out the PPM without a PPM meter...unless you have the eyes of Superman.

Well it drained out about 2 litres I checked the ph of the run out cuse that’s all I can do until I get my ppm meter tomorrow . But the ph coming out is at 5.87 it’s a bit low and I always feed 6.3-6.6ph . I flushed with 6.5 ph spring water . How soon do I feed after the flush? When it dries out? I’ll check the ppm on the run out as soon as I get it . Thanks

Testing the PPM a container filled with the runoff isn't going to tell you anything. You need to catch the runoff in a cup, and test that, multiple times throughout the flush. You can put the feed in right after the flush.

Thank you
