Can’t tell if my plants are suffering from nute burn or light burn

Hey y’all,
I’m currently doing my second grow ever, growing 4 plants of Skunk XL under a mars hydro tsw 2000 in a 3x3. The nutrients I’m using are biobizz grow+bloom.

I haven’t had any problems up until now (week 4-5), but recently the tips of the new leaves in new growth have started turning yellow/white.

I can’t quite tell if it’s nutrient burn or light burn but based on googling I assume it’s one of those too.

Would appreciate some help in figuring out what’s wrong with them. Here are some pics.

not light burn try to feed it less ppms by a 1/4 of what you were feeding it. maybe up the calcium a little get some microbes in there working for you as well .

Looks to me like nute burn on the tips.. but the leaf edges look sharp and crispy almost. It may not be light burn, but that looks like light stress. How close is the light? max power?

I agree. A bit more water and some cal, Epsoms spray. Get the ph right. Looks a bit low.
