14Days Old Lemon Haze in Coco - Need some input!

Hi all...just started a new grow, Im using 8L pot with coco + perlite.
Using GH nuts...feeding according to their week one chart (it worked perfect last time).

PH is 5.5-6 / EC : 0.7 / Runoff : 1.1.
Light : 400w MH.
Temps : 74-76f, 50%-58%

So like i wrote, with my little experience everything looks stable but
still, you can see the yellowing starting...Its my first time with Sativa
so maybe im doing something wrong. Any input will be great, im really
confused here.

Thanks!

Maybe toxity I am not sure.

Well I'm growing an India strain. Based on the growth, your baby is just beginning its vegetation stage.

First thing is check your temperature or the ballast (dimmable). Next check your feeding, (ppm or pH). You might have to pay close attention to your feeding.

Based on your soil, (assuming it's pre-fertilized), how many days have you gone not feeding your plant?

My advice: bring your Ph around 6.0, 6.5 the highest.

Also know your strain and what it likes. Such as Ppm, nutes, and pH levels.

Lower your EC a bit. Rising PPM indicates plant is drawing the water off but cannot take the nutes up.

Thanks all, As for my soil, i flushed it till the e.c was the same as i watered
so i dont think that this is the problem. It seems like a ph problem im not sure why.
Ill try to feed with 1/2 strong and ill update you in few days...thank again!

Anyone has some info a bout growing this strain?

I wouldn't go any lower than 5.5. Raise the pH slowly. The correct pH is the pH the plant wants. Rarely does a plant want an exact or specific pH solution throughout its entire life. You will eventually learn to adjust accordingly.

With pH always make changes very slowly. Small pH adjustments have a major impact on the medium.

Thanks again, ill update soon
