In short, yes....
For small scale it takes some calculating but I reduce everything to square feet and use milliliters for mixing on small scale.
Get a couple of 5-10 ml syringes.... easy precise application.
If you want just a basic full spectrum nutritional base.. use their Macropak and Micropak.
Yes, "documented useage"... I do a lot of videos on this type of stuff...
I'll share a few of my playlists here related:
If you need more specific advice, I'm glad to help.
I am (now in last 4months) using their Fieldlark AI to guide my nutrition program. On my farm operation I tend to also use their plant sap testing... it's EXPENSIVE but VERY good at tuning a crop into perfect balance.
Fieldlark AI gives to 10 free questions...
I have a monthly subscription because it is invaluable in my operations. 75 questions / month is $29.99
I HATE subscription anything... so you KNOW it's good if I'm willing to part with $30 / month.
