And I’m laughing at your ridiculous answer. Had a real good belly chuckle over it. That’s not toxicity and a badly nitrogen deficient plant in early flower will benefit from a nitrogen boost unless you want tiny yields of crap buds that’ll struggle to make it to finish. It won’t effect trich production at all because he’s deficient as fuck. You never..and I mean never let your plant lose all the fan leaves to deficiency in earlY flower. You’re going to get someone to kill their plants, sparky. Keeping them green til later in flower is a good thing. Give it veg nutes for one feeding atleast...3/4 strength and next watering give it bloom at maybe half strength back to back feedings. First veg and then bloom next. Then bloom every other feeding all looks well
