Whats up with the leaves & this plant?

Noticed a bit of this a cple days ago & figured it was a slight nute burn but wld like to hear from other fellow growers. What doya guys think?

yes, i agree with you, slight nutrient burn, i would level it off that looks perfect, they are nice, good luck

i agree as well. doesnt look too drastic though.

It does look like the beginning of nute burn,

looks like its only occurring on the bottom leaves.

thats a peculiar detail I noticed as well. ppm is controlled but i have added soluble silica & aqua shield most recently too. its at like 890ppm now
