Light burn?

[Dani smoke]

Can anyone advice further , it's the first time me using the hlg 600h and I think I possibly burnt my leafs, I think light burn as the lower leafs or not affect to the top ones, pH was also a tad high at the root zone foods EC is 1.2 there 6 week into flower just , root ph is around 6 in the run off anyway

Kinda looks like light burn. How close was the light? Nice buds though

Well they was around 20inch if that before I realised the burning was the light there now alot higher but the light intensity is unbelievable and because the lower leafs rnt effected I think it's the light , the buds rnt effected and won't be now as I say lights 30inch plus away now, buds look like there goin to be decent tho
