Hello internet stoners, for as long as I can remember I've used a 70/30 ratio of coco coir and perlite to start my seeds outdoors and I usually mix powdered mycorrhizae into my starting soil. This currently isnt an option for me because I dont have any powder mycorrhizae right now and if I order some it wont arrive in time however, I use doctor earth's organic tomato, vegetable and herb fertilizer as an amendment in my regular soil. This brand of fertilizer contains mycorrhizae. I'm wondering if it is safe to mix some in with my seed soil without burning my seedlings? ALSO Just today I picked up a bottle of " organic fish fertilizer 5-1-1" do any of you guys have experience with this brand? If so what were your experiences and how did you apply it (how many tsp per gallon, how often did you apply, when did you start to apply and cease to apply?) ALSO ALSO my coco coir is from a "burpee" 36 cell seed starter greenhouse kit and my perlite is miracle gro (dont shame me.I couldn't find anything else and I was racing the clock, i did flush the miracle gro perlite a few times though to try and get most of the non organic fertilizers out of it) I seriously reccomend you try using one of these burpee brand 36 cell seed starters, I picked one up for 5 bucks at my local hardware/everyday yeehaw stuff store . It came with a drain tray, a 36 cell rooting tray (Reusable), compressed coco coir pellets and a clear lid that keeps the humidity in. I myself soaked all the coco pellets until expanded fully, broke them up in the drain tray and mixed perlite in, depending on what the general consensus is I may mix in some dr earth fertilizer and then put back in the cells.
You can mix the Dr Earth stuff in no problem, even for seedlings. I use it in my coco based mix at the recommended rates on the bag. I also add some bat guano and bone meal. I start my seeds straight in this and never have a problem with burning. The fish fertilizer I would hold off on for at least a week because it can be a little hot. Normally it's the quick release nitrogen that really tends to burn plants. Sent from my phbgf uijj tplkjn
