recommendations online, especially youtube or IG et al, is all about comissions and kickbacks. they get the product for free, so they sell it - some don't even make comissions, just the free product, lol. These people are not genuine.
So, be wary of social media mopes selling things. can't believe i have to say that part. They are calculating shills.
there's nothing wrong with any fertilizer as long as it provides what is needed. Depending on whether you are soilless or not impacts what you need.
my problem with this lineup is the cost and the needless number of products it splits things up into. there's no need for 3 maybe 4 parts to a fertilizer. Really, 2 parts can do it. they dye it for the consumer's visual enjoyment, like it's some sort of sugary cereal trying to attract toddlers - along with cartoon graphics, lol.
fertilizer ingredients are commodities. this means there are not varying qualities of ingredients - though there are varying options to provide each element of nutrients. ammonium nitrate is always ammonium nitrate. magnesium sulfate is always magnesium sulfate - down to the atoms. It's like generic Rx - same exact thing as the brand name drugs but not overpriced.
So, nothing wrong with it, if it is priced well and available to you. Wouldn't be afraid to try new stuff, either. One thing is for sure never pay for "ph-up" or "ph-down" these are simply cheap acids and bases you can buy in regular form at 1/5th the price. pH down is probably all you'll need to use more times than not and you can use common white distilled vinegar (5% acetic acid). Think that sells for 3-5 usd for 3 gallons vs what? 10-20 for 16fl oz? they are knowingly gouging their customers - which i see as only a sign of deep disrespect. A common practice in marijuana branded products.
