Bud without a photo we can’t tell you the problem there are so many variables it’s countless.
You could have more that just a nute problem however I’ll give you a idea
the flowering nute you have is kinda useless sadly I don’t know a shop sold fert that won’t have any k or that you could use to fill in the lack of p and maybe n
You might find a organic solution im sure some of the other more hardcore organic folks than me know
1% n thats end of harvest like the 1.10.1 guanos however you have to add sulphate of potash to that especially near the end coz during the last few weeks they Lap up k
It’s got 0 p during flowering you want a high p say 4.15-18.7
The 15-18 is a rouge guide of p
The k is 7 so that should be fine
The added (0.6) is more lightly mg
The numbers that you have tbh I can’t see a use for
Maybe you could add the 1.10.1 guanos it’s low in n & k it has enough p however guano Is slow release and I don’t know if it would work out for you using both you might well be better off getting one dedicated flowering nute that suits your plants needs.
The thing with guano is it’s slow release so the high n I use in grow carries over enough till I switch to 4.15.4 and add sulphate of potash plus cali mg then later come where your at I can use 1.10.1 and top the k up again because of the slow release nature of guano.
Where as bottled nutes are not that slow release and I don’t think the two will mix it might I have just never tried it hence why I’m very Apprehensive about advising both and saying you might be better with a decicated flowering nute unless someone else can help that all I can offer bar good luck
