some guy, can you possibly take a photo of the plant with the light off before you bump up the nutes? the plants color is being thrown off by the orange tint and i cant really tell if the color says nuteburn or a diff, is the ph ok? i see splotching that could be a calcium or MG diffiency which could be an underlying PH problem and then i see secondary veins that say its getting a burn in a way. i cantsee the color on the edges of the ;leaves really. if they are browning from the edge then nute burn (you have a bit of a strong fert for veg at full strength now.)
looking at plant size and dosage and what i can see when i lookinto the leaf is either back off nutes or just get ph in the zone.... but the other coloring looks like its hungry (could just be because a diff. of nutrients from ph)
we really need a photo under some flo. lighting to make a "proper" judgement at this point.
