Does this look like a magnesium deficiency? Getting some yellowing around the edges of some lower fan leaves.

This is burning from feeding too much or too often,.....or both.
Acapulco Gold being a sativa requires much less feeding, especially nitrogen, than your typical indica or hybrid.
Cutting your feeding in half should stop this from getting too much worse.

I had the same with my Lemon Haze 3 years ago. It was a ph problem (too high) which caused lockout troubles. The nutrients were in the soil but because of the ph value the roots weren't able to take them up. U are growing in hydroponic and i have no experience with that but a "flush" or change in water for hydro to the lower the ph would be my guess. After that a slow build up for nutrients and it will be fine.

Leaves burned after spraying a cocktailTo repel aphids I sprayed garlic infused in alcohol with water, already did this few times without side effects. But this time I added several drops of tea tree essential oil. Is it possible that the essential oil has burned the leaves so much or is this some nutrient deficiency?

Bio Grow burn vs Bio Grow boostHi, it seems like she keeps getting nute burns as soon as i give her Bio Grow, even at half dosage (1ml/L).
She has only 10 more days of veg and i wanted to boost her, what if i stop giving Bio Grow altogether until flowering?
Is the tradeoff worth it? No burn but less growing?

Is it time to feed nutrients now or can I wait?I have not given any nutrients yet but I'm wondering if I should.
1. Are these really signs of nutrient deficiencies?
2. Which nutrients are missing?
2.1. My guess is P, N and/or Mag, Cal. Is that a good guess?
3. Is BioGrow a good choice to address these deficiencies now?

Can I use magnesium sulfate foliarly?Hello, this plant is at the beginning of flowering and apparently has a magnesium deficiency, right? Can I use 100% Mag Sulfate from the pharmacy via foliar treatment? I'm using Calmag 2ml/L but it's not having any effect.
I should add Dolomite Limestone to the soil this week.

Possibly Potassium Deficient? Based on ALL the pics I could find, but not sure.I noticed these brown splotches and leaf edges on one area bud and pistils of my Orange Sherbet last night. Based on what I can find online, this might be potassium deficiency?
This is mostly on one spot near darkest edge when tent closed. Thanks!

Grower questionAny ideas what the issue could be?
Few weeks into flower. Dealing with fungus gnats and have kept the population very low.
Temps do get high, at most 95 (hot I know). I cranked down the lights to their lowest setting (100 true watts LED).
I have adequate air flow.
