Going to use Shogun Sumo boost during flowering an...

Nice grow you have a nice nutrient line up there. I would stick with your plan but start adding in lower dose of PK 13/14 about mid bloom then keep going and give your max dose just past the 3/4 bloom mark in order to get the most weight on those buds. Yes use a TDS meter to make sure you know whats going in and coming out of your pots to make sure shes feeding/eating all the nutes your giving her. I usually like to add some silica to my grows it builds stronger cell walls on the stalks and leaves to help support those heavy buds. Plus it adds a bit of extra potassium to the mix make sure to use it sparingly it's very alkaline and should be added to your water first before the rest of your nutrients. Hope this helps👍
