Wrinkled leaves slow growth

Hi guys,

First let me be clear on what's what.

I am a new grower only my third grow.
I am using 2 x 600 watt has and 2x 400 has as you can see in the pictures.

I am feeding bio buzz grow and algamatic as per Instructions,
I have a 4250 exhaust and 3 750intakes temperature no higher than 28 no lower than 18 with light off I am running a 20/4 cycle

Some of the new growth on a few of my ladies are slowing and showing wrinkling and brittleness of the leaves. Image read a Lot on this and there seems to be many probabilities.

They are definitely not overwintered as ionly give them two litres each per week on average I lift my pots and judge by weight.
I have sprayed them now and then without algamatic could this be the issue?

I have posted pics circled in red is the wrinkled leaves and blue is the normal growth for comparison.

Any ideas?

If you are spraying with your lights on it's possible you are inadvertently burning your leave, hence the "crispiness". Not sure what algamatic is, but whatever it is, I'd only spray right before the lights go off.

I spray before the lights come on.
algamatic is a vitality stimulant by bio bizz.
If it was burning the leaves would they not discolour?

Any ideas on the wrinkling?

Thanks for the help

If they are 600w I would lift the lights to at least 12" or more, could be reason for crispiness & wilting looking at your pics ?

Could it be low humidity? Rh is somewhat strain dependant,but ideal is %50-65 during veg and about %40-50 while flowering.

Slyone, it may not look it but the lights are more like 20 - 24 inches away bro.
The twist in the leaves shows no sign of stress apart from the twist and wrinkles

My humidity is consistently 34 /40.
Would this not effect all plants and leaves rather than a few and newer growth?

Apologies, pictures can be deceiving... Eye test is on the way..... I'm afraid....

Have you checked for pests on the underside of the leaves, as they may not have spread to your other plants yet, (Just a long shot) as they can be very tiny ???

Yes I have checked everyone thoroughly.
I'm baffled could this be some sort of nute problem?

In my experience only, the few times I have see that on mine is either when the light/heat is too much or if I am over watering.. I like to rule out some basics first. I have also grown different strains together and have also observed some strains like 18" - 24" but the others prefer 24" - 30", from the light when that small, and have had to adjust and find a "sweet spot" ??

Like I said rh is somewhat strain dependant.I should have also said that it's probably just those that don't like the environment.They'll probably grow out of it.peace

Over watered ?
