Andy, as I've stated plenty of times...I'm no expert, especially with fertilizing. But, it seems that about the only things I've seen that were stated to benefit from feeding the grow-mix are sarrs and drosera regia (especially as seedlings)...maybe neps and other pitcher-types? Most of the time the fertilizer mentioned that was used were Osmocote pellets...just a few, maybe four or five pellets scattered around the plants maybe an inch or two away from the crown...and pressed down into the soil a half-inch or so. They're slow release so it's not a big splash of fertilizer hitting the roots all at once. The pellets can also be dropped into the pitchers...I thing only one or two pellets per plant...but I don't know the frequency of feeding the pellets...I'm sure it's here on the board somewhere.
But, I suppose using Maxsea would work, but you've gotta get the solution correct. As Chef said, flytrap king was going by PPM and a feeding schedule...to translate that over to a volume amount of fertilizer would simply take some testing as you slowly add some Maxsea to the water. Test the gallon of 1/4-tsp strength Maxsea solution you have...if the PPM is too high (over 50ppm) then add some water to the solution and retest...if the PPM is too low, then of course you would add more fertilizer to the solution. This is, of course, if you want to follow flytrapking's instructions. Most uses of Maxsea that I've seen has been for foliar feeding of most any plants and for direct feeding of pitcher-type plants.
Naturally, the safer route is to let the plants catch their own fertilizer or either feeding them bugs or fish food of some sort...flakes, bloodworms, beta-min pellets, etc.,.
I can definitely understand the desire to give the plants a good, swift kick in the nether region to give them growing quick and healthy.
Btw, is there a specific type plant are you wanting to feed? Beware of sharing water trays between sarrs and regias that you might feed heavy and with regular flytraps and sundews. The latter can't handle the fertilizer that well and enough of the fertilizer can leach into the water tray to affect them adversely. Of course, I'm probably telling you what you already know but it makes me feel useful.
