Looks like a Nitrogen deficiency, but I would start with checking your pH.

Leaves fading and dying, started from bottom but spreading
I’m starting to be at a loss with this. Calmag issues earlier in veg, seemed to improve for a while but now bottom leaves started to die - I thought this was just due to beginning of flower but it’s getting worse and spreading even to healthier new growth. PH (should be) fine.

Day 38 autos: is this nitrogen deficiency or something cal mag could help with?
Kia ora whanau, Each of my three flowering autos (the Herbies Beginner Auto Mix #1: Ape Fruit Auto, Purple Chill Auto and Godzilla Cookies Auto) has an issue with yellowing older leaves. Do I need more nitrogen or is this potentially something cal mag would address? TYVMIA!
