Well my guess is it’s pretty much the oldest leaf on your plant and that is why it yellowed on you! This is why we do defoliation! As your plant grows new leaves these big old leaves die out! 🍀👍 you got nothing to worry about! 💯🤟

New leaves have yellow and/or curled tips (-> nutrient burn?), and many leaves have their edges curled up (-> root problem?). The pot that I'm using is fairly small and only has a small hole for drainage. Can this develop into a serious problem?

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.

Should I do full flush til runoff is 300ppm?
So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it? Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow. Today 3L water, pH:6.2, runoff:0.6l, ppm:1450, Ph6.0

Defoliate yellow leaves?
Should we remove these large yellow crusty leaves near the soil? The plants are at about day 38. I've heard people say you shouldn't defoliate this early in flower. Should I be concerned about these leaves dying off or is this normal?

What is going on here? Started off as a Calcium deficiency so I upped the Cal/Mag, but the problem only seems to be getting worse. It only has 2-3 weeks left so I don't want to do anything too drastic. Any advice is appreciated!
