Spots on leaves, turning yellow. help:)

Hi.
I am using biobizz nutrients. Super lemon haze. 250w.
about 70% humidity, 25c temp.
I have those bad leaves and its looking sick. what can be the cause ?
Thanks.

Can you get some closer pics to the really effected leaves?

What is the feeding schedule and BioBuzz what?

Looks like under feeding. Do you own a ppm meter?

No i dont own a ppm meter.
My second grow.
I am still using the small pots. 3L.
The soil is always wet. if i let it go dry then it gets worse.
I used the biobizz nutrients for roots for the first time...
The plant is in its 6 week.

When should i transplant? trying to scrog
Feeding them with about 250ml a day

It looks like overwatering to me, that cause the ph to go low, eventually locking out nutrients and micros.

Well i own a ppm meter and im at week five and a half in these pics. Theres no magic here. Just a two part base nutrient line and calmag added twice. Feeding at around 400 ppm in soiless. The only advantage i have over you is i know exactly what im putting into my plants because of the ppm meter, but thats all i need. A ppm meter is the most important tool you have when it comes to growing. Without one your like a carpenter without a tape measure and ill see you in plant problems time and time again.

Didnt feed it for 2 days. starting to look good again))
Thank you!
