Fine-Tuning Nitrogen Understanding (Deficiency or Toxicity) -- Suspected deficiency, so how do I adjust Fox Farm nutes? Increase ALL 3 nutes to 3/4 dose?

TCH0808started grow question 4 years ago

Initial inter-vein yellowing, followed by whole leaf yellowing. Minor leaf stem reddening. Older growth. Normal for flower stage (I believe), but too early for normal and rapid discoloration (week 6). This makes me believe it's a nitrogen deficiency, amplified by SLIGHT overwater

Yes, that's definitely a nitrogen defeciency. Flowering plants especially during the stretch will still need a considerable amount of nitrogen on their feed (some strains more than others) 🌱👍

I just fed a 3/4 dose of Fox Farm Tiger Bloom (light 1/5L watering) to get a small boost between waterings and correct this issue soonest. I'll proceed w/ 3/4 dose of Tiger Bloom for future nute sked, vice previous 1/2 dose. All good? Also, should I increase the other two nutes (Grow Big and Big Bloom) to 3/4 or stick w/ the 1/2 dose?

Vexatious yellowing I can't get to correct.This Northern Lights auto is being vexatious...I can't get rid of the yellowing towards the bottom. Not overwatered, I've tried beefing up the nutrients, etc. with no effect. Any thoughts or do I just writing off as she's just being a jerk? Other plants in this grow are fine.

Yellow dot on the leaf.Yesterday I watered with fertilizers. The dosage is 0.8 grams per liter. PS in the area of 5.5. The instructions say 4 grams per gallon. 1 gallon = 4.55 liters. Everything seems to be correct, so I do not understand what the problem might be.
