Has anyone ever used the fox farm three pack on autos? And do you use 1/2 the recommended amount?

What medium are they growing in Growmie, a lot of cannabis friendly mediums are pre-charged and will feed the plants anywhere from 4-6 weeks with H2O only
Fox farm happy frog. I did autoflowers last summer outside and used Robert Bergman fertilizer and schedule. Did ok for a Minnesota summer now indoors and going with fox farm nutes but I heard you should only give half the amount on autos than photos.

FFHF will feed the plants for approximately 4 weeks and would go to your run off PPMs around that time. Less than 800 and it’s feed time. I treat the autos I grow exactly like photo period plants. Same nutrient strength 850 PPMs

Personally, I use happy frog fruit and flower 4-9-3 and bypass mixing nutrients. You could top dress with it now, and by the time it breaks down, your soil will be ready for nutrients.
I just did my first round of fox farm grow big yesterday they’re almost 3 weeks old. I will definitely consider that next round.
Is that something you mix in with the soil before planting?
I usually do mix some in with the soil, but you don’t have to. If you don’t I would suggest top dressing a couple weeks after you transplant into final pot.
So I did 4 autos and they’re 3 weeks old from sprout and planted in final pot. You are saying just put some on top the soil? Just starting out thanks for all your help!
Can I top dress my 3 week autoflowers with ff fruit and flower after feeding with ff grow big last week? Don’t want to burn but like the idea
Nice to see another fellow Minnesotan on the forums. I think there’s a few of us 
Yes I bought some ff fruit and flower and was curious.
