superthrive is mostly B vits
you want some kinda sea kelp extract, just buying powdered triacontanol is normally best way, 100mg makes .5 to 1L of spray once you mix it up, I like a little bit of fulvic or I use some Halo, I don`t know if that harpin protein does anything but the cheated iron seems to help the triacontanol get absorbed when spraying it
Or just get a bottle of seaweed extract liquid, mix 1g of triacontanol per L of seaweed juice, then use it @ 10 to 40ML per gal, from week 2 to week 6
Can hit them with it in veg too if you wanna bush them out
It`ll make a good spray too if you get a seaweed juice that can also be used as a follia
