They are in supersoil and have been feed by F.FJLooks like micronutrient deficiency there with the red color on the main veins, maybe Fe or Zn IDK though
For the record the light was way close to the leaves have pulled it up, Its in supersoil,No only water but avery 3 weeks use to give1tbs molasess in 2L bottle alyhough I have given this mix once only ( 2tbs of F.F.J+1tbs of L.A.B+2tbs of molasses+2tbs of wermicompost in 5L water,temp fluctuation between 20-23.5 c@Growing freak
It can be hard to help diagnose a cannabis problem based on pictures. A few answers can potentially help pin point what areas to look in search of your issue. What nutes are in your super soil for N-P-K & micros? Is this veg or early flower? Do you add anything to your watering's?
I havent feed them except giving them some molasses and L.A.B ,- A light like yours is powerful. My recommendation for early flower: 24-30" above the canopy @ 300W (50%) strength.
- Your temps and humidity are good.
- Your super soil mix has a solid list of nutes. Your plants appear me be fading to me. Rather that is a PH issue(plants cant asorb certain nutes as good or at all when PH ranges are off or a lack of the amount nutrients in your soil)
I question how much of N-P&K is in your soil and at what point is it available to your plants?
Since you are in early flower and seeing how light green your plants are my recommendation is to top dress a 1" layer of worm castings across your medium on all your plants and observe any changes in your leaves for a week. It's important no matter what you do to remember it takes time for your plants to show improvement from an issue and to try 1 or 2 things and give it time to see if that worked. Since you're in early flower your plants want veg stages nutes by applying worm castings:
This will give a gentle dose of nitrogen, and provide microbes and benefical bacterias which will promote root health, and help what is in your soil be uptaked by your plants. All things needed for your plants right now.
I personally like to add dry amendments (organic) as top dress so I can introduce nutes as needed as they progress in veg and in flower.
For the first 3 weeks of flower your ladies should be getting the same nutes they are given in late veg into early flower.
But, you're in a super soil so it's hard to manage this as you go along.
Humic/Fulvic acids are great for breaking down your list of super soil products so they're more readily available to your plant for uptake and incourage your plant to uptake.
Its when you hit week 3+ the uptakes of P-K are more important as bud formation begins to develop more.
As far as molasses goes it feeds microbes but what about the population?
I would focus more on adding/replenishing the microbe population.
Do you use any products for microbes like recharge? This is a one step powder from you can add to your watering's and does what a compost tea can.

Tehy are in diffrent pot but they use to be in the same pot from the beginninghttps://www.rollitup.org/t/need-help-with-this-plant.1065851/
are they in the same pots as from this post? see the burning tips? you had it too hot way back then. You locked something out, then the plant ran out of what was no longer available even faster from watering/ feeding often.
I have ph up and down and RO water can I use it in organic soil?Guessing that it's too acidic, I would take a stab at watering it with fast acting dolomitic lime, IE: Garden lime..
Follow the directions on the package. (it should be like 1 tablespoon to a gallon of water) You will probably want to do this with every other watering or every 3rd watering. (Especially if using molasses which is acidic,(depending on kind, some molasses is more acidic than others and some molasses is actually alkaline).
I personally would drop the molasses and just focus on getting the plant right. You can add molasses at the last 3 weeks of budding and get the same effect from it, as if you added it at vegetative. (I personally find molasses imparts a really weird heavy choking smoke, so I never used it again.)
Being that the lime is "Fast acting", you should notice a bit of improvement of the plant within the first 24 hours. Definitely within 48.
You really don't need all the amenities that you added to the soil to get good weed to grow. Simple soil is easy to diagnose and makes life less complicated for the plant and for you.
