Nutrient deficiency or excess

Hello All,

I am a little lost on what my issue may be regarding this grow. Plants are doing awesome and do not seem stunted. Trichome production and bud grow is pretty decent, but my leaves are starting to brown and die. Seems like a deficiency of either phosphorus or potassium. Would I be correct in this assumption? Plants have roughly 3-4 weeks left and I’d like to get them corrected to make the most of the last handful of weeks before harvest

What nutrients have you used? Looks like a nitrogen deficiency or acidic ph in soil runoff. I’m dealing with the same thing but after a good flush and addition of some veg nutrients, they’re starting to turn around.

Im using some mirical grow organic nutrients. I know people tend to stay away from MG, but I have had no problems with their products to date. I’m using bottled RO water that has a PH of 6.5. Considering it’s only affecting the top half of the plants I’m inclined to believe it’s actually an immobile nutrient issue which would throw nitrogen out of the equation. Could a lack of chlorine cause this issue as a deficiency of chlorine turns leaves bronze colored? Also the soil is fox farms ocean forest
