i have 2 plants i've been vegging for almost 5 weeks now. the older, lower leaves are turning a pale yellow, basically dying because the edges are turning brown and crispy. top growth looks pretty healthy except for the tips which are starting to yellow.
from what i've read it sounds like a nitrogen or magnesium deficiency but i'm not certain. i'd like a diagnosis so i know if i should flush my plants with some pH-balanced water or just feed them more nutes. i am using the foxfarm stuff wih ocean forest soil.
