What to use for "sweet" during flush?

So this is my second grow in my homemade bubbleponics system using Fox Farm nutrients. I'm using the full line including big bloom, grow big, tiger bloom, all three solubles, kangaroots, and microbrew. The only thing I haven't used is their soil products and the sledgehammer flush between rinses. I'm pretty pleased with the results, however, after my first try with the nutes, I'd like to try to use something special to give my girls that nice sweet flavor for smoking. Does anyone have any suggestions, aside from molasses?

I'd like to avoid molasses for a couple reasons. 1. To avoid gnats, bugs, critters. 2. To avoid clogging my pump.

I'd love to hear from ya'll!!!

Oh, just wanted to note too, that I'm growing White Russian from Attitude.

awhile back. someone on here had posted that botainicare was giving away free samples of sweet and all you had to do was email them and ask for a sample.. being a freebie kind of guy, i was all over this, and went to the site, found the contact us info, and sent them an email asking for a free sample.. low and behold, about a few weeks later, i got my free sample.. about another month later, i got a second free sample..
i've been using it since, but i have to admit that i don't really notice anykind of sweet flavor to the buds..not sure if that is what this product is supposed to do or what.. if i hadn't gotten it for free, i don't think i would have purchased it.. and once my last bottle runs dry, i'm sure i won't buy another..
i also just read another thread about atami giving out free samples of their bloombastic and rootblastic.. same deal, just email them asking for a free sample.. i did so, and just got a return email like two or three days ago asking me for my info, and whether i was a hobby grower, or a retalier.. so hopefully pretty soon i should be getting me some free samples of that as well.

nice.. i'm also growing out one white russian from the tude this grow.. so far im really impressed with the wr as i planted her a lil later than the other plants, and she has caught up and passed the chemdawg x bb and the sleestack from dna..

Has worked pretty good for me.
