I understand that I'm in week 2 of flower and 3 on another plant I dont need alot of Nitrogen at this stage
I'm confused are you learning growing or are you an expert?
For someone with no previous experience you seem reluctant to take the advice given.

I'm confused also. The op is right. He doesn't need a lot of nitrogen in flower, but is he asking for advice on what to do, or just everybody's opinion?

No I'm not an expert I don't think anyone thats posted on here is an EXPERT but definitely more experienced than me im more than happy to take advice i just got confused by everyone telling me to cut the N down alot and people were saying that 5 N that far into flowering was to much

I'll make it simple... don't listen to them lol.

5N means that entire bottle has 5% nitrogen. Thats neither meaningful nor meaningless on its own.

How that 5%N is used in your watering mix, and then in turn how it used by the plant are whats important.

You can use a 20-0-0 on flower if needed, but the amount and dilution rates are where you would need to be cautious because of the concentration of the nutrient. With that said, dont use a 20-0-0 in flower lol, as most bottled mixes come with exactly what your plant needs.

I checked out the Humboldt secret line, and it is an A+B all the way through, and golden tree would be your "micro"... so in this instance, because AB is actually just a grow and bloom, you likely could cut back on your part A some if you wanted to. BUT you aren't showing signs of N issues so there's no need to do that.

If i were you, id follow their chart, using the lower side of their application rate ranges (says 5-9ml, id use 5, or 7-10, id use 7, etc). The reason being, is that underfeeding slightly is an easy fix, and will be just as noticeable as over feeding, which can cause serious damage fairly quickly. But otherwise, id still go by their recommended applications, and like you said add a PK booster (which id start around week 4 and then taper it out towards the end) to make up for where its lacking.

Give us more pictures without the blurple light on so we can see what she looks like

Thank you for taking the time out to type all that bro lol and yeah thats what I was thinking i think cutting it out all the way would be depriving my plants of what little N they still need in flower i am using 50 ml of base B per 5 gal. And 20 ml of the base A and the low end of golden tree and low end of the flower stacker as well also just got the enzyme and the sweet and sticky additives that I havnt used yet I figured I would just try the whole line

Overwatering + overfert, can look exactly the same as heat stress. Especially in combination with poor aeration, poor drainage, low ph and root disease.
Both heat / low humidity problems can look exactly the same, because the leaves are dry and crisp either way. Plus overwatering and overfert will only make it worse.

I'm not good at spotting pests. I do think you should look for mites really thoroughly. Especially in all the canoe shaped leaves.
It was over watering, low rf and genetics because the other plants had no issues lol
