Still a relative noob, so please excuse my ignoran...

Hello SoopaNoobie, your girls are looking great. Most of the time fertilizers are expensive, and its almost always devided into veg and flower bottles. You actually need N-P-K as food for your ladies, more N in veg and more P-K in flower. My advive on the nutes, try one where they have and combo discount pack with everything in it for the whole lifecycle. (Booster included) Than you always have enough feeding for that growth. Do not forget to buy an ph- or ph+ to correct your ph. Hope this was an helpfull answer my friend. Keep on growing. Peace 👍🏾

Expense is a relative condition, and yes anything designated for cannabis is like buying something for a wedding, pricey. You can use almost anything if money is dire, tomatoes (best) are an excellent substitution when looking for nuets as are most flowering plant mixes. Dr Earth is very reasonable and organic also available though amazon if not local. It a top dress type but dont let that scare you people been doing it for hundreds of years and it works. Bio-Bizz like most liquid organics is pricey but it lasts, know a lot of folks like it I am not so sure. It works fine just not entirely happy with it this summer. Here is the deal: Tomato dry organic is cheap and only requires a bit of thought, any deficiencies can be addressed as normal you just dont add more nuets but rarely. Two packages the veg (grow) and bloom (flower) could take you through a whole grow, that aint bad. All you normally after the dry is applied is add some cal-mag and PH the water and feed. Everything else is in the pot. Cal-Mag in soil is something you must deal with apart if its needed I fear. Some coco nuets like cocotek have it there already. I will be using Dr Earth outdoors this summer.

To be true you just need 3 Products, One with N for the vegetation, and one for Bloom ( P+K) and in the transisition to flower you use both fetilisers. And maybe in the End a blooming booster. So normally you dont have to feed her with N until you see yellowing on the older leaves. Because your soil has a lot of nutrients inside. I f you start to fertilise just start slowly with it... less is more, and if you see how plants respond you can up the Dosage.. but you have to wait a few days until you see all effects of the nutrient ( 4-5 days). So just get any growing // blooming// boost from any fertiliser company you can find here on GD. My Favourite is an Organic Liquid Fertiliserline ( Green Buzz Liquids) their starter Pack is full of beneficals and additional stufff for healthy and happy plants. The Starter Pack was enough for me to fertilise 16 Plants. But you can take any Of any company... just go with seperated fertilisers one for vegetation// one for blooming// and a booster. There a re mixed fetilisers too. but i wont recommend them
