rapidly yellowing top leaves
Week 7 auto. She was all green a few days ago, but top and bottom leaves now rapidly turning yellow. Soil run-off is 5.8PH and 700ppm, so I suspect some sort of deficiency here. Any ideas?

Deficiencies at Day 60 or natural, expected fade?
Does my girl look like she is suffering from a deficiency or is it a normal fade for day 60 since sprouting? What can I do as she definitely has a while to finish I feel? Any estimates on how much longer she has before getting close to chop? See most recent comment for details.

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!

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!

Discoloration and burnt edges on leaves
Can someone please help me diagnose this problem? At first I thought it was root dry spots from the drip watering system but it’s gotten worse. The bottom leaves are yellowing and the edges are burnt with a hole in one of the leaves. Anything helps, thanks!
