My question is concerning mixing fertilizers in 5 gallon potting soil-filled buckets.
I have 1 sativa dominant and 1 hybrid plant (bagseeds) that are just beginning to flower. The last two times I have watered I have used normal water with no ferts to flush it out. Today I made sure to rinse the two plants out really well for the third time with regular water. I wanted to flush everything out before I start fertilizing for the flowering stage. The next watering I am hoping to fert them with their flowering mix. I recently purchased some Vigoro All Purpose Plant Food that is labeled 15-30-15 and has almost all the "micronutrients" except for magnesium, which I will just sprinkle epsom salts onto the soil to make up for that... as I have been for the whole grow since my veg fertilizer (Peter's Professional) didn't have any magnesium in it either?
I also bought some Premium Vigoro Bone Meal that is labeled 1-11-0 since I've gotten the impression it's pretttty good for the plants! A wee bit of Nitrogen and a good shot of Phosphorus...but I also want to make sure they get all their micronutrients. That is why I want to mix it with something.
My concern is that I might end up over-feeding the plants Phosphorus.
If I were to use 1 teaspoon/gallon of Vigoro 15-30-15 All Purpose Plant Food with Premium Vigoro 1-11-0 Bone Meal, how much Bone Meal should I add, while keeping my plants completely safe from lockout of other nutrients?? (assuming I'm not messing up already) I'm not sure if it helps, but the recommended dosage is 1 TABLESPOON/gallon of the Vigoro All Purpose Plant Food.
Any help is greatly appreciated, as I am pretty excited since I've got two very healthy and good looking females! I will post some pictures soon since I finally got the digital camera...
