Help please diagonse why plants are light green new growth Nealy yellow tip and edges

[Richiegrade]

Help been told I have phunkin mite also plant look light green

[Aussiehomegrow]

I use canna a b I mix 5 ml a +5ml b to 1.25 litres with an e.c of 2.0 and then I adjust ph to 6.0 it just looks like they need a good nitrogen boost

[Aussiehomegrow]

Buy a good boost I just mean full strength feed not to go over the recommended mixing ratio your plants don’t look to bad I’m sure just a few days with a full strength feed should have them looking green hardest thing is waiting to see results

[Canuck147]

Don't look too bad at all, really. We all get a bit of nute burn occasionally - go easy on the nutes. Clones?

[Richiegrade]

This is what I mean mate ive hardly give them any give them like a 1/4 of the feed but thaylook really light green like that need more food but I got Hurt tips and edges never had thisproblem before

[Richiegrade]

Why are that so light green if it's nite burn looks like deficiency help

[Richiegrade]

Yes there clones mate why are that so yellow

[Canuck147]

Bring us up to date on your whole grow - pH - soil?- how old are they ? and all the rest if you want specific help.

[Canuck147]

Most important part of the plant is the roots - you got happy roots the rest of the plant will follow. I say that cuz a lot of new growers with clones don't establish their roots good enough at first.

Looking at the pics what do u think mate do I need to feed them only been giving them 10 ml of a and b per 10l

[Mr.furley]

You need to drop you ph to 5.8-6.2 for coco, you have lockout. Time to flush

[Richiegrade]

Do I flush with plain water my water out tap is really soft can't see how flushing is going to help Coco normally buffers its own ph

[Mr.furley]

So do you check the pH of your water before and after watering, coco is not self adjusting.
