Not septoria but burning from severe nitrogen toxicity would be my diagnosis. Feeding too much or too often (or both). Not watering to run off each time can accelerate the problem.

Do I have a deficiency problem or am I ok? 3 lower leaves on both plants started with the tips browning but now the leaves are going yellow. None of the newer growth has been affected but the 3 leaves seem to be getting worse. See pics in week 4!

What happens if fan leaves all fall off before maturity?
This is first time ive dabbled with ilgm autos. Plants grew twice the recommended size and are on the 9th week. The pistols are 90% white and the fan leaves are yellowing fast. I've never experienced this and am afraid the yellowing will affect buds before ripe. Suggestions?
