I may be wrong but I’d say I’m 95.99% sure you have nitrogen toxicity.

the plant looks overfed and at some point, they hardly grow, like only 1/5th of normal grow.
I don’t know, never measured. I’m feeding with bio grow, bio bloom, top max, canna boost and cellmax alga max

Well may I suggest that when you are ready to get serious and wish to invest in a valuable tool, grab a blue lab SOIL pH meter. It will read liquids just fine and can also test the soil (root zone pH). I consider it my most valuable tool. I also have the Apera PH60S (spear probe). Love those meters and they finally let me pinpoint why I would have a random plant shit the bed when others of the same strain, age, feed were fine. Your medium pH is not always what you would expect from your input pH.

I’ve noticed this when I’m over watering hot soil. It just seems to sit and not want to grow.
It’s 7 weeks now, I don’t think it going to grow anymore..

Thanks for the astute observation. My point is you can see its over watered and over fed. Those things stall it. If it’s over watered and over fed now. It’s probably been like that for weeks and weeks.
Yeah you’re right. What can I do now to save the savable?

1 let your plant get “too dry”. So dry you’re like oh shit that’s dry. I still use a probe if I’m unsure. You will see the plant look sad and the leaves will look tired. The pot will be light and when you stick your finger in it....it will be dry for about an inch or first knuckle. THEN when you water with those sad leaves and the pot a little bit too dry. It will perk up right away!
2 decide if you’re going to take this serious and get some cheap TDS and Ph meters. Even a cheap soil probe. All for under $75 probably. If you’re not going to take it seriously good job water it Only from here on out and enjoy your 1/8 bag

Dwarfy strains are just that dwarfy. You have n tox ( claw ) which you don’t want during flower.

A couple things that can cause N toxcicity when you really don't have a shit ton of nitrogen. Low light levels. So you have a plant thats given a good strong feed but it's not able to really use it with such low rate of photosynthesis. Another factor is plant size. A runty plant can have the same issue with feed strength due to it's inability to process that much food. So when I see signs of a nitrogen deficiency (claw) but I don't see leaf tip burn as would be expected if you had a hot feed, then I suspect low light levels and or runty plant (both of which we have here).

yes, give only water until the plants new growth appears in healthy green colour (if it even happens since you're already in flower...)
Your plant hasnt typically N burnt signs because youve fed your plant with A+B flower formulae (Grow + Bloom = NPK 3-5-5 (avg.)) plus 2 Bloom/PK boosters, one having NPK 0-10-10-12 (12=Ca or S ?) which is further unfavourably changing the NPK mismatch...
So either only give Grow+Bloom OR Cellmax (both solutions contain enough PK for flower).
Use BB Fishmix for Veg (NPK 7-2-4)
And only TopMax OR Cellmax not both.
And only TopMax OR Cannaboost, because Topmax also is a booster containing both chelates & aminosugars. (but no NPK)
indeed, heres a diagram illustrating the speed of growth in relation to the availability of N:
