need your expert help peoples

hey every one.

I have gone through a few of the posts and "sticky's" posts but can't find any pics of plants with the problem I have.
So I was hoping someone could take a look at my pics and give me some advice.

I've been growing my plant for about 2 months.
everything started out perfectly.
plant was growing fast and healthy.
It even split it's stem by itself!!!
but for the past week or so it has been getting worse.

the tops look ok.
But the leaves and all drooping and the bottom ones are going brown yellow and dying.

I've attached two photos.

I took a look at the ferts im using and it has all the things weed needs to grow.
and I know someone who used it and got amazing results.
before I try to remedy the situation by increasing or decreasing the concentration
I want some advice from the experts so I go the right way 1st time and don't kill my baby. Cause she has so much potential.

let me know guys

thanks
Baba

Looks to me like some nute burn. They may not be big enough to outgrow the pots yet, but I would check and see if they are rootbound, also. Too many roots in too small a place is not good. I would check your PH in your soil, and water with ph balanced water for a day or two, and see if they come back. Looking like she has some potential, so I hope she comes back for you.

I am no expert at troubleshooting, I usually stay away from issues by constantly checking my PH, and using large pots for my plants.

what is your ph reading ?? and your watering schedule IMO
I would flush your plants with water ph being 6.3 - 6.5 save the excess runn off and check your ph from that
looks like nutrient burns as well as nitrogen defiency from your pics so i am thinking ur ph is out.
As well whats room temps and humidity levels in your grow area in veg try for 72 degrees and 60 - 65 humidity for veg hope this helps you but really flush your plants with distilled water
