Bloom booster I think?

We have a local company that mixes nutes and labels them for others. I have been buying from them since begining hydro with i think good results at a fantastic price, $25.00 for 4L of A+B. My question is i have just purchased a litre of a flowering additive. It is 0-30-20 and is concentrated calling for a teaspoon per 25 L. Would i gain anything by using this throughout the grow or should it only be used near or at the flowering stage? I used Overdrive in my last few grows and was happy with the results but not the price 😳.

mj will only use P and K the most at the end of flower, although it is needed throughout, iwouldstick to using it from week 3 of flower until the end, otherwise ur prob just wasting it...i dont know everyone is different though, good luck

You probably won't need it, but it can't hurt to have if you already bought it.

If it runs out, you can just buy dry mono potassium phosphate which is the same thing but more pure and cheaper.

Mono potassium phosphate is 0-52-34 NPK rating. It's one of the main ingredients to all hydroponic solutions, but usually marketed as a bloom booster when sold individually.

Thanks! I will probably hold off until flowering then. It is alot cheaper than overdrive but I would suspect OD has more in it. These guys at the nute factory will actually custom blend nutes so i may start to play with some things as the season progresses, need to get the first trays finished though as the reserves r running low 😔. Its been a long hot summer!!! Just started the trays yesterday, with some White Russian and some Critical Kush, cant wait to get some more of the critical, woohoo!!! Had really good luck with the critical last spring and the White never fails to impress. Fyi the nutes are produced by EZ-GRO and they do ship, prices are really good as well. Pay for the nutes not the name and pretty pictures on the bottle lol. I have tried a number of products side by side and the local guys seem to be as good or better re: results at a way lower price.
