Hi there ! I think it's a nutrients burnt as I never saw a def leading to burnt leaf/leaves ! As it been told to you , your fish mix ratio is too High , 10ml/l should be the dosage to "prepare a soil" but not with every wattering. Your plants colours is clear , I think you have a slight nitrogene def but as you'll get in flowering soon a little add of N should change that ! Hope it will help you ( PS: can you tell us more about your PH & EC ?) :grin::+1:

Hey man, i had the same thing happen to me. Basically, what i understand is the Fish Mix makes a high PH for your plants, and some of the more sensitive types of plants will eventually become unhappy. So what i did was wait until the next watering (the dry/wet cycle is important!) then just go with some plain water. try going with bloom nutes soon, also : they often have the correct PH, and can start your flowering aswell. btw : i'm adding molasses every watering now, and my babies love it ! A+ :muscle:

It's phosphorous deficiency. Add some bloom nute and you will be fine. Be careful with fishmix, 10 ml/lt is quite a lot.
