I would pass on the GH nute kit, the bio bud and a few others work fine but the rest is a waste, iv had a couple of people i know waste there money on that, it works but not enough for me especially when you are on a budget like i was a couple of years ago. Also wasted money on clearex not worth it, hygrozyme is, but you dont need it man. Dont believe all the hype around all the chems and shit, dont get me wrong, iv got everything from Advanced Nutrients all the way to foxfarm and GH, most is all bullshit though man, you would be surprised what you can do with one bottle of nutes some good soil or water depending on your grow methods. Here is what i did when in my first run on all organice chocolope back in 2010 useing nothing but the $30 box of sunleaves international house of quano nothing else even locol soil nothing special. And the last 4pics are also way back in 2010 first run at pineapple express in hydro, with the help of scottyballs on this site, i used just one bottle of GH Flora Nova bloom from seed to finish, nothing elses planted seed directly into the water farm. I got almost 5 ounces and vegged for only 26days, all on my first try and iv never looked back. I live in a non med state, so the more you can harvest for less is better. I dont have hydro stores or anything where im from. Iv spent 1000s on chems and it not worth the money, iv started alot of people over the past couple of years just by what iv learned from scottyballs method in hydro or the sunleaves bat guano soil method. Of course the company is going to tell you that you need it, and your plant wont do shit without it, but most of that is all lies, some of course work really good but until you have the money to waste dont bother thats all. The one i would say i use the most is sunleaves peruvian seabird quano, plus sunleaves sells a chart with that sunleaves international house of guano, and then you dont even need a ppm meter, for this its simple just add table spoon measurments per gallon. I recomend a PPM/PH pen but i personally now what its like to be growing on a budget when your a begginer and cant affort alot of things, but i never feed without testing PH and PPM, but i didnt for a long time, and always had good results in organics. Look up scottyballs pineapple express from seed to harvest, you can see what he did with one 400w light, one waterfarm, and one bottle of GH Flora nova bloom and he got almost 10 ounces off one plant, its a beutiful thing to see, iv been refering people to his grow for years now.
