Some help

[Taktookato]

Hey guys,
Third grow over here and need some help to identity a problem I’m having.

3 weeks into veg, I have some yellowing on the bottom leave. Mum growing in soil. Gave my babies bio grow for the first time about 2 days ago.

My ppm was really high(2500) around a week ago. I believe the soil was too hot cause I only gave root juice. i flushed them 700 ppm.

plants are under600w hps

Can anyone tell me why are my bottom leaves like that and what should I do


Many Tnx

2500 is way too high, what is th ph going in and out
The leaf damage will never come back, just new leafs will be normal

The ph in is 6.4. Out is 6.2.
Ppm dropped now.
will everything be ok

Give it a few days and watch the leaves that are not damaged yet, if they stay fine then I say you had over fed , and to cut back on nutes
If it gets worse then I would look elsewhere . The PH looks ok lil low but not too low to lock the plant up.
If you can go a lil higher on PH plus , 6.5-6.8 is where soil likes to be.
All in all the plant looks OK, just very bushy , what light are you under ,LED ?
When was the last time you put her in new pot/ that is if it is a reg photo and not a auto plant?

Are you feeding ever water? I do Feed , feed then wate ronly (just to keep the ppms down)

The flush might have caused a Ph swing in the soil temporarily. Yellowing on the bottom leaves is natural as it sends its stored energy upwards to the new growth, but your leaves look like they have a bit of brown and crunchiness at the end, which makes me go to the Ph hypothesis.
