Is it this or that?
My best guess is Overfeeding.. I sat down to try nut it out, but I only guess. What is the deal here folks?

Yellowing and dropping of leaves
Does anyone have any ideas what could cause the yellow and dropping of leaves for the Royal Jack. All plants are treated the same. The growth is stagnating as a result.

Некоторые взрослые листья покрылись точками и желтееют (смотри фото). В чем может быть причина и стоит ли их отстригать?

Did I give too much fertilizer??
So I decided to add in some soluble fertilizers. I gave it a 1/4 tsp (50% of recommended dosage) a couple days ago and noticed some yellowing of new growth on the bud sites. Is this a sign of excess potassium and phosphorus? I gave it Fox Farm Open Sesame (5-45-19).

Just checking in here, I am pretty sure this is light stress. it was at 18" (specs say 18-24" during veg) and she was likely pretty stressed after having her top cut off!!! I have raised light to 23". Am I on the right track here?

Is this due to the sun and hot weather?
Some parts of some leaves are looking like they're burnt or something. Is this due to the sun? Or do I have another problem? It has been extremely hot last week (around 35 degrees all week). And the plant has been in direct sunlight (I've moved it into the shade yesterday)

Yellowing/ leaves dying
Beginning of week 4 flower and my girl is losing bottom leaves faster than I’ve ever seen. They are yellowing and falling off quicker than I think is healthy. However I also have burnt tips so it shouldn’t be due to underfeed. Rootbound maybe? Let me know

Black tips and spots on the leaves
I'm having problems with the leaves. I estimate that the plant has about two or three weeks left to live, and I don't want to have issues now. Some tips are darkening, and spots are appearing on the leaves
