This mother plant has been having 2ml per litre for the last 12 months and been fine. Last couple of weeks its gone down hill. . Think the e.c is 1.0- 1.2

Yes mate coco its a 20L pot temps have been stable. I recently set up a drip system for it and some smaller plants. Ive not been getting much run off of the big pot because i stop the pump when the smaller plants have had run off. Do you think salt building up could be the problem

I'd give it a flush, proper good flush and make sure the ph meter is reading right. Then 2ml/L at 5.8.
See how she does, if she looks worse, up that to 3ml/L.

Personally I'd have her on 3ml/L anyway. But that's me liking them nice n dark.

Good luck dude.

il give that ago thanks pal

Yeah I think if you combine your theory with what marcus has said it kinda falls into place

I was thinking that after 12 months the coco calmag buffer may just be out, but with the potential salt peaks I think that's exactly it

Give it a really slow run through as slow as ya can to get the medium really well reset and I think you'll be fine

Be worth nipping off the shitty leaves afterward so ya can see if ya get any new leaf issue. Them ones ain't gonna get better as I'm sure you know
