When to use growmicrobloom on northern lights autoflower In fox farms soil.

Okay so I added another layer of fox farms to buffer any mixed in manure. I will go ahead and watch for signs of nutrient deficiency around 30 days. And will go ahead and check ppm come feeding time. Thank you all!

I would not put any manure in the mix next to seed, can be exactly in that spot and will burn root or seed with too rich environment or will change pH of that area and grow can be harm from get go .... All the Best !

autos like a weaker concentration so that's good you will use it as a lower rate. I'd suggest getting a TDS pen to confirm its EC/PPM numbers. FFOF - fox farm ocean forest soil can be hot. You may not need the steer manure in their just yet. Might want to save that for a top dressing down the road. Your call. Good Luck and Happy Growing!
