problem wit h2 easyryder. deficiency or burn ?

hey dudes. i really need some help with these easyryder, it's getting worse everyday. i Think it's a combination of N and MG deficiency but it oculd also be burn, since i bumbed up the nutrients, since nothing seemed to happend when i fed nutrients.
i'm using potting soil with leca in 6.5 L pots.
i use water with a PH between 6.0-6.5
I'm using lucas formula with GHE nutriens, 16 ml bloom and 8 ml micro. and have gone up to 3/4 strength.
i checked runoff and it was 6.2 PH
here's some pics.
Thanks

I reckon lockout, flush with ph water, could be a salt buildup in the pot, I'm not a soil grower maybe someone could confirm this??

This a hydro grow? looks like it, keep it at 5.8. Flush it, and stay ontop of ph. Try adding cal/mag too.

nah this is a soil grow, says in the description before the pictures
but thanks anyway

IMO in any grow if its all going wrong and u don't know what to do for the best, add less... Flush, half nutes build up gradually and keep ph in range...

i think i will flush it then, thanks for your input
i just have one more question, how much water should i use for each pot ? they are 6.5 Liters. and what should the PH be ?

Just water em once till there bout 20% runoff coming out bottom a good good drain then let her sit till she feel empty if you check by weight.....or check soil few inches down
And ph 6.5 preferably for soil but in-between 6 and 7 it should stay can't wait till I get my ph meter
