Why is One growing perfect the other is struggling
Why is one of them doing so well growing better deep green leaves and the other is at least 2 inch shorter and leaves are yellowish. I’ve been feeding them both the same I’ve missed the shoter one of the soil is still damp. I’m guessing nutrient over load so thinking do a flush

Yellowing leaves on autoflower dwarf
I'm 12 weeks of vegetative growth deep with an auto-flowering dwarf strain. My plant is nearly 1.5m tall, showing no sign of flowering but I'm starting to get a number of yellow leaves lower down the plant. What is causing this? Should I leave or remove them?

Day 40, I recently discovered my ph meter was faulty and my soil ph is high 7.3. I’m going to do a flush today with just water 6.5ph. I’m using living soil. What do you think will this be good for them? How do they look? My data shows me a daily average of 80.5F and 58% RH.

Yellowing of leaves Week 9
Help! Is it normal to have such yellowing Week 9? The buds are still green, but the bigger older leaves are quite yellow. Same strain different plant still very very green. Might be the difference between topping an auto and not topping an auto?

Yellowing Leaves
I'm concerned my plant may be prematurely yellowing. I've added Cal-Mag to see if that would help with the yellowing of leaves, but the issue persists. Yellow leaves are moving progressively higher up the plant, but my other strain is not presenting same problem. (See Post)

I need advice on what to do with this plant. I flushed her a bit and I think nutrient burining is not showing on new growth, what ppm should i feed her?
I watered only last week and mesaured runoff ppm and ph. Water was 350 ppm and 6 ph and runooff was 700ppm and 6.7 ph. Before when i fed her with 850 ppm runoff was 1500 ppm. I would continue to water only but there was a lot of yellow and pale leaves so gave her light dosage.

Is it possible that maybe I underfed my plant and that's causing my actual problem? Is it something normal? Or there's something else going on with it that I should check and fix fast? In general the plant has a lighter green color and old leaves are getting yellow. Thanks!

What’s wrong ?
This plant has displayed this yellowing in a couple of its older leaves. It hasn’t gotten better with the exclusion of nutrients it doesn’t seem to be hurting the growth of the plant as it has continued to grow over the past week. Is this something I should be concerned about?
