Perhaps in these pictures you can see better, what deficiency this is, whether it is phosphorus, potassium, magnesium or zinc?.

Looks like potassium to me. Do not raise your nitrogen level in process. Your well fed there. Always be aware of run off ph and tds or ec.

My second plant is really a midget compared to the other one. Should i be worried? Hello! Growing this Wedding Cake Auto for 10 days, and it's 2 times
Same environment for both plants. Spaces between branches are super narrow. The stem is weaker than the other plant and leaves are curling down. Had a Ph issue earlier. Now giving her only Ph - 6.5 water. Will she bounce back? How can i help my plant? Thank you for your answers!

as you can see on some picture some leaves have burnt edges, others are 80% yellow-ish and few have yellow dots. I thought that I gave too much nutrients so I've been giving her only straight water for 8 days and more power light for 4 days. No improvement it's worse now. Please

Having some nutrient issues. A few leaves are yellow with brown tips (first couple pics). I also had some nute burn a couple weeks ago after switching to GH so I lowered my feedings. Now I’m confused if it’s an excess or deficiency or something else? Any help much appreciated

Flush?
I have never tied to flush a plant and I seen if the leaves have too much yellow then it is not a good idea. I plan on doing a harvest in 10-14 days and wanted to know if both of my plants should be ok with a flush.

One plant smaller?
One of my 4 plants is much smaller, the stem is much thinner and the leaves bend downward a quite an angle but otherwise it seems perfectly healthy and is still growing. Not a serious question just wandering if anyone had any thoughts on this. (Far left in the picture)

Autoflower week 9, not flowering
So what should I do, there's no signs of switching in week 9! I've tried changing to 18/6 lighting, but have only been running it for a couple of days. Besides that she is really droopy and the soil feels really hard (maybe lots of roots). Any advice is appreciated :)
