Newbie troubles / leaf damage!

Hello guys hope you are doing good!
I have some troubles with my plants
I’m on veg day 7!
coco-perlite 70/30
Watering every 2/3 days 100/200ml.
There is a damage on the top of plant any idea what is happening?
thank you in advance.

That can happen if you spray anything under intense light, nutrient overload and or root zone stuff and pests can do that

thanks for your comment.
Well Couple of weeks ago I had issue with spider mites. I spray them with spider mitte liquid and I switch off the lights.

On 8 little water
4.2 mega crop
1 ml power si
4ml cal mag
8 ml regen a root
200ml/ 150 ml each pot.
my EC 1.2 to 1.4!
If this make sense.

I’d just spray for pests and watch the nutrients and ph closely so that they don’t stress.

EC 1.4 is too high for plants that size. Keep it at 1.2

I pretty much get everything but ec, sounds reasonable enough. Only rec would be possibly dial it back a tiny bit, not much tho

So should I reduce nutrients -30% ?
Thanks again

Yeah Give or take 10%, dropping down to 1.2 would probably be enough.

Id maybe go lower to be safe and work up incrementally

Are you watering to 20% runoff every time?

No :-/
I have 2 litter pot.
how many ml should I water?
usually I water 200ml!

You should water it until you see runoff, otherwise you just have nutrients accumulating in your coco, which is likely the source of your issues.

Well today I decide to flush them.
300ml water, 6.5ph, 0.4 to 0.6 EC
I measure my run off , some plants 1.6 EC and some others up to 2.2 EC.
I guess I overload nutrients.
