Too much or too little nutrient availability

[AMurKyX]

Hello all, i am a newer grower but have been growing house plants for some time. I have been following mr.canucks on youtube and have been mostly basing my grow off of his. In this post i will address my issues and concerns as well as a dive into what i have going on. Issue number one, i have three old clones that lived too long in their solo cups. After they have drooped and scared me half to death, i though i was losing them, but a heavy watering and transplant the day after they seemed to be taking well. The transplant was done probably two weeks ago. While all three are now showing some signs of discolorations and drying, one of them is far worse than the other two. The largest one, tropical runtz, has severe yellowing and even a little bit of browning on the edges of fan leaves. I have been using gaia greens organic living soil, earth worm castings along side the gaia greens organic 4-4-4 and 2-8-4 nutrients. I mixed a full bag of potting soil and added in 2tbsp of both nutrients per gallon of medium resulting in a 50:50 ration of nutrients at the recommended amounts. They are getting about 300-400 ppf at cannopy height from a 700w flora flex light (newly upgraded roughly around the time of transplant) running at 50% currently. A small ac infinity fan blowing through them gently. Now im concerned because the yellowing is slowly progressing to other fan leaves and id like it to stop so the plant can grow healthy. The growth has slowed down. And if youve seen any of my other posts, you will know that these plants are more important than the autos im growing for myself or the three im growing for a friend of mine until they can go to his place and be transplanted one last time. First 3 pics of tropical runtz (most concerning) and all following pics are pf the other two clones that may be affected similarly to the tropical runtz. Any help will be greatly appreciated before i jump the gun and start flush. Thank you guys.

I've had plants do that when they got too much P/K while in veg. I'd cut back on the nutes a bit (particularly P/K 2-8-4) , the leaves are very dark green, so it definitely has enough N. I would not flush a living soil, just use plain water for a couple cycles.

How do i gauge how much water to give my plants based on size. Im worried they might not be getting enough for proper root development. The dirt avoids the edges of my fabric pots and runs out down the side so i water slowly. Ik over watering is harder to do in fabric pots and even more so in an air pot (might switch to air pots for next run) but i still only water about two gallons spread among all the plants somewhat evenly. Ik if the roots havent filled the pot then it may lead to waterlogging where the roots cant fully uptake it thus creating root rot so ive been very careful

Water until you get about 10% runoff, water slowly, around the edges, you're trying to get the roots to chase the water and expand into the pot. Then let the soil dry back before watering again.

Will this help at all with the soil slowly receding from the edges of the pots?

Thts a potassium deficiency
What are you feeding?
If your using a chart should be at full strength rn at about 2L for tht size of plant
The run off method is better
You can pick the plants up everyday this good for knowing when to water get used to the weights of the pots wet nd dry
