Yeah it may not hey. Not really much point if it does either lol.
Good work on the sleestack skunk too, should be nice and ripe now
As for your nutes mate, the jacks classic is equal parts nitrogen to potassium and phosphorus which isnt ideal. Higher nitrogen and phosphorus is ok in veg but higher potassium wont get taken up and it has also been linked to higher ratios of males if used in week 3 of veg (i'll have to find the reference). It will still work ok but may end up locking out other macronutrients at high levels of 1:1.
The foliage pro also contains kore nitrogen, phosphorus and potassium but in lower ratios which would help more. If you feel your plants need more nutes, id be giving more of this than the classic. You could even get away with just using the foliage pro.
I couldnt find info on the jacks blood food but the ratio it describes is pretty good for flowering. The higher phosphorus and potassium will work well to fatten them buds
