I got 9 clones from the same mother plant that have some strange coloring on the leaves.

They started out really bad seeing i kinda forgot about them.

They stand under 4x97watt cree 3590 4000k distance of about 80 cm and currently at around 30.000 lux.
7L Smartpots.
Temp MAX 28 degrees and MIN 24 degrees.
PH 6.5 EC currently at 1.3 incl 0.3 from tapwater.
Currently 400ml a day per plant using 0.5 ml calmg, 1.5ml biobizz grow, and 2 drop of aptus regulator per liter of water.

Checking the leaves everyday and can't seem to find any bugs or something.

Hoping someone knows what this is so that i can do something about.

Thanks in advance.

Looks like slight bleaching from the Led... My cobs will do the same..

Could make sense seeing it's only happening on the higher leaves and not the lower ones.
Would you recommend hanging the lamps a bit higher or doesn't it hurt to much? It's been like this for a few days already and it doesn't seem to get any worse.

Starting to get Mg deficiency. But I also see bug signs too. You need to use a loupe or microscope to check for bugs.

This room will actually be mixed soon using 800 watts HPS ad 400 watts LED. Waiting on a few things like mylar films and new fabric pots for my 23 White Widow seeds and an air cooler as well seeing i'm going to need it once i turn on the HPS lights.

You got an answer for this as well perhaps?
Seeds are about 10 days above ground. If i switch those next week to 12/12 once they are in bigger pots they probably keep growing for another 3 weeks i guess seeing they're still to young to flower am i right? ( kinda new to seeds as well seeing i always used clones before) I kinda have to switch it because otherwise my clones will get to big.

There will be 32 plants in total in a 1.10x2.18 room so 2,4 square meters.

Well if it's a Mg deficiency that problem should be solved soon seeing i already started giving them calmg from aptus since 2 feedings seeing i read about it being need more under COBS.

They will start to flower on schedule.. It' kinda weird, I did a 12/12 from seed, had preflowers in 3 weeks..
Makes it easy to cull the males...

Well i got feminised seeds so that won't be an issue. How big did you're plants eventually get and what was the average yield using that system?

The whole thing turned into a disaster... I started10 seeds, got 7 males.. The 3 fems were huge single cola plants but they got bud rot.. So I really can't say for sure.. I'm sure it would produce quite well with clones..
