Yo towel...

how big is your system? (gallons) I'd say 500-600 ppm is good for a plant that size... what is the ppm of the tap water you're using?

the GH 3 part is good shit... although when you flower, if you use all three parts, there is too much Nitrogen, which will slow down the flowering process... i use the "Lucas formula" which doesnt use the flora grow for flower... there is plenty of nitrogen in the Micro. I'm not sure if you've ever heard of that but its like 5mL per gal of micro 10 mL per gal of bloom ONLY DURING FLOWER... its from Overgrow - same as me, when it comes back you can search over there for more detailed info.

are you using any other additives?

put'em at 500, even if thats a weak solution - they'll still take off and blow right past a soil plant :thumbsup: then just increase LITTLE by little.. till you see the tips of the leaves burn, then back it down a few ppm... (like 100-200) thats about the max you'll want to give that plant.. if you have 2 different strains in the same hydro system (usually discouraged) you can only give them as much as the one who likes the solution the weakest... know what I mean?

peace mang... and good luck!
