Well I would have done a few small additions if I was gonna max it out but I thought you were pretty much doing a water only but hell yeah ..hmmm,lets see if I was gonna slap em lightly id use(you got LEDs sooo) prolly 10 drops of cal mag if you havent hit them in a watering or two.if you hit them last watering id personally go half strength of your normal unless theyre overdue.
Sugar in the raw i would use a cpl teaspoon and wait till it disolves after a few minutes stirring or shaking whatever.prolly wont take that long just make sure its disolved and Big bloom id use about 2-3 Tablespoons. ,and as ya know stirring often.thats per gallon too.dont need to drench em unless youre toasty dry man LOL! but that way they'll get a decent taste then a half watering of plain water in another few days then a tea..Thats what id do.but you can drench them too and just slap em with a tea whenever.you could even do a half ounce of kelp liquid too if you have enough or just a small taste again with 1-2 teaspoons with all the other additions and lightly give your plant a fair sip and then the half watering but ive prolly already confused you LOL
a gallon water use 1-2 teaspoons liquid kelp if you want
2 teaspoon or 3 of sugar in the raw
2 Tablespoons big Bloom and either half or fullstrenght depending if theyve been treated recently.
