For supplements, lately I'm using these:
CalMag- My well water gets weird in spring during snowmelt, and starts to resemble a very dilute and disturbingly pure organic acid solution... HELL on the buffering capacity of the soil, and only a couple mg/L CaCO3.
Stacker/SnowStorm/PurpleMaxx- They keep changing the name of the product but it's real nice stuff. I give it as a foliar so as not to interfere with soil chemistry. I have had mixed results with Humboldts Own products. This time around, my results are stellar. The plants look rolled in pixie dust!
Sweet- I use this at about 5-10mL/gallon along with some extra sugar from unsulfured molasses.
TopMax- Better product than Sweet, but more expensive by far, and overkill in my garden since I use the Sweet, molasses, and will on occasion apply Gravity. But I love TopMax and if you pick only one bloom booster, this is my top recommendation for especially newer growers, since it is pretty foolproof and works well.
Canna Boost- Everyone gets this- rooted clones, veggers, moms, flowering ladies. It just makes them seem more vigorous. I'm not sure that I'll go buy some; the shop guy gave me a free sample, but some outdoor people I know just ADORE the stuff and I am passing their recommendation along to you-all.
Note that I do not run high P bloom blasters as a general rule. I've got some Grotek stuff but have only used it a couple times. I feel that my standalone bloom fert is already giving adequate results, and I don't want to overdo the macros.
stinkyattic Reviewed by stinkyattic on . Additives and supplements for flowering in soil I was wondering what additives and supplements everyone is using and/or has liked during the flowering stage when using soil. I have read all the post on here, but most if not all are for hydroponics which I'm not sure if they are okay for soil or not. The ones I've seen listed on here most are: Topmax, Liquid Karma, Kool bloom, and Calmag plus. If anyone has used these or any other products I would be glad to hear their success or failure. I am in the 1st week of flowering just so everyone Rating: 5
