Did you get all 3 solubles, or is Open Sesame the only one you got?
One of the problems with the solubles in the FF line is that if you use too much, it does damage. Not enough...and it's a diluted waste. Personally, other than the Nutrient Trio I've only used the Cha Ching. (mixed results, but I'm unimpressed)
And regarding the Open Sesame and Sledghammer, cannabis has been flowering without assistance for quite a few eons, so I am unimpressed with the concept of spending money to have the plant do something it's going to do anyway...and you can get a great flush with plain, properly ph'd water. I love my FF nutes, but am baffled by their solubles.
