Jack Herer/strange leaves

[Zaxar]

Hello Friends!

So here is my lovely strain jack herer 8 weeks old growing under Viperspectra 450W in soil.
distance between plant and led 60cm.
Everything was going perfect until I noticed those strange leaf problems.

I was not able to check PH last time, I will post it when I'll find out.
P.S. I'm going to switch to 12/12 tomorrow and Im worried a little bit about this problem

Would be glad to hear your opinions

Thanks in advance!

Wind burn maybe? Idk I'm new to this. Just looking at the diagnosis page and trying match your pictures.

Hi Z If it were mine I would skip a feeding then switch to bloom neuts and start at 25%. Maybe wait another week or two for 12-12

Not sure what concerns you the most, but here is what I see and what I would do:

too much Nitrogen (starting to claw)- foliage growing faster than roots with not enough Calcium (curling) and slight iron deficiency (light terminal buds).

Stop Nitrogen allow pot to dry up a bit.
Water with a Ca/Mag product (which usually has iron, too)
If not add a micro which has iron.

hold off the flip until you see it begin to recover- then you are good to go.

I'm thinking that's a ph problem with them claws, an like Primo says I'd wait till I got my problem fixed before I'd make the switch, but that's just me and my 2 cents, nice looking plants though.

So here is what im going to do.
flush her with ph'ed water and switch to 12/12 and start adding cal/mag with bloom nutes
