Clawing and yellowing leaves

Hi, I got some discolored and claw leaves and I'm not able to understand what's really going on:

Light burn? Wind burn? too much nutrients? my fabric pots are dirty and I was thinking that this could block oxygen transpiration making my leaves to curl.
-9 of 11 weeks of flowering
-temps 78 to 82 F
-humidity 40 to 50%
-5,8 Gal pots and I water twice a week 1/4 of the pot volume.
Only one plant has discoloured leaves, the second has a small amount of purple on the tips, both have claw tips.

Are you checking soil moisture before watering ?

Not really, in august temperatures were higher (85/90F) and after 3/4 days leaves were drooping down already and I never changed watering schedule since that, ofc before watering the top of the soil is always dry.

Could be a root zone, bugs, ph, or too much light issue. You should be using enzymes if you aren't already. I've been dealing with root zone bacteria recently and my leaves would claw like that. How far are your lights and how much watts?

I have 2 spider farmers, one sf1000 (100w) and one sf2000 (200w) for an area of one square meter, I also have two 25w purple light with two more 14w "house lamps" to give some more green light. I always check my water's ph and soil's ph (6.3 to 6.7), I have no bugs on leaves, idk for root zone bacteria.

ppm? Do you water to runoff?

I can't tell you the ppm bcs the TDS is broken, but I can tell you I never put more than the recommended quantities. I'm sure the ppm is not under 1000 and I mix my principal pk nute with purpinator. I don't water to runoff, all the water is absorbed by the soil

I'm thinking that salts have built up in the soil causing burn.. I would water to runoff a couple times then go with half of what you usually feed.. See if that helps..

it is very likely thanks! but I have also noticed that the lamps are very close: 15inch from the sf2000 and 11 from the sf1000 (the plant in the first pic is under sf1000) is that too close?

Id try and Let your soil dry up abit.. then on the next watering dont use anything other then alittle of your nute and some epsom.. the epsom helps kick up nitrogen uptake..
My guess is a possible lockout..
Dial back dont use and additives just your basic nutrient and work up from there.. the idea is to see whats causing the problem..
Get what im meaning here.. im stoned and not sure if this makes any sence..?

My other thought was light burn.. I run mine at 18-20" So it wouldn't hurt to raise them..
