Yellowing Leaves

[GrowerNew]

Hi,

Yellowing started on the leaves and two leaves torn. Do you have any idea about the cause and solution?

Jack Herer - Photoperiod

18/6 - 160w CFL Lights. But She is on the balcony during the day.

1/1 Bio-Grow

Water - boiled and rested tap water

Note : It's been hot here for a few days. She stands on the balcony during the day.

Thanks.

Overall it looks good. Pretty color also. The spots could be s small PH problem. What Does your PH level say ?
if it’s not a ph I will guess a cal-mag problem . With the brown/bronze color.

the 3. Picture could be a little bit eating of your plant during the day outside - looks like somebody chewed on it

I keep at least 1 day after boiling the normal tap water. I don't know the PH value. The lowest ph water I can find in the place where I live 6.8, After that I will water with this water.

Too me it looks like PH fluctuations - or a cal mag problem as I suggested. It’s always a good step to measure PH at the right levels. So the plant have easy access to the nutrients it needs.
Do you feed it cal mag ?

No, i don't use cal-mag. I'm using only bio-grow 1ml /1 Lt per week.

Is there cal mag in it. ? Because it’s a vital nutrient for the plant.
