Autoflower Nutrients

If their autos start at 200 ppm from sprout and work your way to 600 to 650 ppm by increasing your ppm by 100 every week if you see good growth. They max out at 600 to 650. Only give more if they really need it...

the instructions for dose can be wildly different per brand. it's a good idea to calculate the ppms from label using an online calculator or make a spreadsheet for re-use with a simple input. regardless of what they instruct, a 600-650ppm ballpark is probably safe place to start. 120ish/40s/180ish NPK then the rest in secondary stuff that may vary more due to differenes in tap water in some cases. By knowing the gist of your ppms, you can make apples to apples comparisons of nute lines regardless of potentially drastic differences in instructed concentrations to mix. even if yo do it one time, you know what you are feeding fairly accurately as you make minor adjustments based on observing plant. take notes for next time as to what worked out. you can start their from the get-go. even in soil this is useful. it will help you learn what you need to add and when to add it, if you use the same components to your soil each time. or, help you adjust amendments to the soil etc etc. it is useful for both soilless and soil grows in different ways as well as some overlap. google manic botanix nutrient ppm calculator (or maybe substitute fertilizer for nutrient?) it'll be near top of search. and regardless, observing and reacting to plant is the only way to dial it in well. knowing what you did on a ppm basis last time hastens that learning curve. or, knowing your weighted average NPK ratio that you fed, etc. helps gain familiarity without less trial and error invested.

Any reputable, cannabis specific fertilizer, organic or mineral, they all do the same job, roughly. GHE, B.A.C. and Bio Canna are all good. With autos, half to three quarters strength is usually plenty strong enough. In soil adopt a schedule of plain water/plain water/feed/plain water/plain water/feed.

Hey Growmie, I grow nothing but autoflowers, and the nutrients that I use are GHE Florabloom and FloraMicro along with Cal-Mag Plus, it works amazing for autos, just use it at 1/4 strength. If you need specific measurements by Week send me a message and I will be glad to give you the feeding schedule that I use. Hopefully, this was helpful and remember ...
