G'day m8, i grow in coco but have had the exact same symptoms as you but over a slower rate
here is some pics for reference

as you can see its very similar

i stared a thread in the infirmary that i got some good answers too here https://www.icmag.com/ic/showthread.php?t=179168

in short i was lacking Cal/mag and my medium was lacking nutrients
Also your ph might be off
do you know what your ph going in is and have you taken a runoff ph and ec reading it could be lockout from high nute/salt build-up
hope this helps

I'll agree with shaunmulok on this one, I'd first check the PH. Having a fucked up a PH can cause you all types of problems. If your PH is on, then it prolly is some type of Nute issue.

Also, I've never used your soil line, or nutrient line, but if indeed this dirt your using has nutrients in it, it MAYBE could be a case of overferting. First things first, make sure your PH is where it should be, then go from there. I cannot agree that overwatering would harm your plants that bad.

And remember, those leaves will never revert back to the way they look, just gotta focus on other leaves not affected, and new growth.

Where do you get your water? Tap? Store? Distilled? Rain? It will determine how much Ca/Mg you need. And the pH.

tap and is run 4 30 sec im going to get a kit to test my soil in a bit ill post it in a bit

I think it's a watering problem. You say 1.5L per day. When cannabis is healthy and vegging at top speed, its watering needs will change daily and no schedule will meet it's needs over time. Keeping the soil too wet can also drive the PH down and cause toxic overdoses, which is what your leaves look like.

The first rule of watering in all of horticulture, indoors and out is; As thoroughly as possible, as INfrequently as possible. That means wetting the entire rootball with each watering (1.5L looks like too little for that pot?) and letting it dry enough between waterings that the roots are encouraged to grow in search of more.

im not too sure about thoes biobizz products, but i know when i see burn,
tell me this;
is your soil getting very dry?
are you using tap?
are you giving food every feeding?

that looks like too much bottled love. or a horrible ph problem(like 8+?)

sorry m8,

but i will argu to the grave that this pic, is indeed burn aswell.
the plant may have had salt buildup,
the plant may have had too much p/k
and still had mag def while getting burned,

but "that claw"

.. indicator the plant is trying to pull more water into the leafs...........
