Should i flush it?to much light?to stressed out cos of the chicken wire? PH?

Because of the way the leaves are folding lengthwise (taco/canoe) it looks like heat and or light stress

whats your run off say ,Biobiz isn,t that a peat mix I wanna say a Mg deficiency that would cause the yellowing, try giving her a round of just cal/mag up to 1200ppm you'll know in a day or two if that was it

[cacib]

appreciated, and what if not? would she survive if this not the case and i give her 1200 calmag?never done that's why, and again input appreciated.

Here's an article on light stress

Judging by the pale green and the slight cupping I'd say heat stress combined with a nitrogen deficiency. Or it could be root bound. 1.8 gallons isn't a very big container unless these are Autoflower.

FYI some strains like it cooler (White widow), some like it brighter (Northern Lights), some more arid/dry (Alaskan Purple)...what kind of strain are you growing?

Side view pic of plant and grow setup would help.

I find it tough to see what a plant is doing when it’s scrog’d. But my first impression is N deficiency, or possibility of manganese deficiency. You could increase the ratio of tap water to 30-35% mix with the RO water.
