Cause of these yellowing leaves?
RJP17started grow question 4 years ago
Bottom leaves are starting to turn yellow with brown patches also appearing on both plants. I think it’s a nitrogen deficiency as I’ve been feeding a little light (around 450ppm), can anyone confirm? How do I go about correcting this?

Hydro. If the plant is overfed, can the ec possibly go down when they are given new nutes ?Usually they eat 0.1 ec when I add nute or with a new tank and ph goes up. Then it stabilizes and ph starts to go down till I refeed since I have a small tank. Right now there maybe a nute block but EC still goes down like they are hungry... Hydro with a small tank is confusing..

Need help identifying the deficiency hereI just started seeing some kind of deficiency on the lower leaves of my plant that's still pretty young. Can someone please help identify? Just tested the PH and it's at 6.4. I'm not seeing any spots on new leaves. Do I ride this out? Do a flush? Appreciate any advice!

Yellowing a bit too soonDuring the second week, leaves started to look a little bit yellow. The first true leaves yellowed way too soon. I'm guessing lack of nutrients. It never showed signs of drought or overwater stress. Your thoughts?

Magnesium Deficiency ? How can I fix it ?got a little deficiency (maybe burned? but I think not).
I'm pretty sure it's magnesium's deficiency, it happens after a flushing. I added 2 times the last 2 weeks a little bit of CalMag (BioBizz, but ive bought it 2 years ago, maybe it doesn't work well idk).
