1st time grower, Mg suspected what cause, nutes?

Hi all,
Starting off with 1st post and already asking questions, I am sure people on the site have experience and are nice to answer this.

1st time grower
soil : peat moss and perlite. Its called Light Mix from Plagron
Water:
From the well 6.1 pH
run off water is 6.2 pH. both measured with Essential PH meter- Hydrogarden Essential pH Meter: Basement Lighting Hydroponics and Plant Grow Lights
Watering when top 2 inches are dry ( every 4 days about )
Nutrients - Algae Grow from Plagron - NPK: 4-6-8 + trace elements.

Plants are 25 days under the light. I only measured the pH of water 1 week ago and realized that its slightly below for soiless mixes so I adjusted pH with pH up to 6.5 when watering with nutes.

Here are the general setup and the main plant that suffers. Other few plants have generally weak leaves with some curled down.
Super Silver Haze, Himalya Gold and White Widow and Auto Ryder x Ak47.

My plants looked just like that at about 30 days.

I think your root bound.:thumbsup: Time to re-pot.

Looks to me like the plants on the right are suffering/recovering from the ph issue. (paleness, the 'claw' deformed leaf fingers at their base)

Do you by chance move those bags around, or do you take care not to disturb the roots?

Is there proper drainage? How much water and how often?

Beyond these questions, filling-out the troubleshooting form is your best bet for a complete analysis. (link is in my signature)

Mg is rarely the solution. It is good at masking real symptoms and can damage your ladies, though. epsom-salts-not-miracle-cure-thread.html

I say they are either rootbound or overwatered most likely rootbound, mine look like that when they get rootbound although you seem to have a pretty decent size pot for plant size. right after you water loosen the soil from the pot by squishing the pot a bit with your hands on all sides flip the pot over and take the soil and plant out of the pot and check its roots, if you can just see some here and there it is ok if they are all over the place and swirled all over the bottom you need to repot.

it looks way over watered to me
Stop watering it and post a picture in a few days.

hi all thanks for your help. I stopped watering and they are recovering slowly. will post pics soon.
I was adding more than 1 liter in each pot every 3 days so thats probably it.
