leaf symptoms

Eh, looks like slight nitro deficiency, but those are also larger/older leaves and the plant is maturing so it's likely minor.

Could be either. Looks closer to deficiency imo but both can look the same.
Take the EC and pH readings of your feed and runoff. If the EC is much higher in the runoff, you have a lockout of some kind. If your pH is off, then your plants may be incapable of taking up the nutes you provide. Recalibrate your pH meter before testing again. If it's one of the yellow ones, consider throwing it out in favor of a brand like blue bluelab or apera instruments. It's worth the investment!

Plant getting lighter — deficiency or excess?Plant getting lighter overall. Thought it was N deficiency. Since N is mobile, expect older leaves to fade first. But its more the top/whole plant. Using Floragard Grow Mix w/ Greenhouse Feeding Bio Grow (1/3 dose due to pre-fertilized soil). Bloom fertilizer was added yesterday.
