Quick Question

For nutrients, I'm currently flowering and using 8-7-6 on the plants for the first two weeks. I have only 15-30-15 (It's Miracle Gro Ultra Bloom -- all I can get) for the flowering stage after these too weeks. Is that too strong?

The analysis is as follows:

Total Nitrogen .... 15%
Total Phosphate .... 30%
Total Potash ... 15%
Boron ... 0.02%
Copper ... 0.07%
Iron ... 0.15%
Manganese ... 0.05%
Molybdenum ... 0.0005%
Zinc ... 0.06
EDTA (chelating agent) ... 1.2%

Its not to strong if that's all you can get (you just use less) Miricle grow is not recomended usually and it does use urea for its nitrogen.
I assume your growing in soil.

Yes it is indeed soil.

It will work then as the urea will break down into available nitrogen. Best of luck

Mix at 1/4 recommended strength to begin. Feed, water, water. Next feeding 50% and the next 75%. By then they should be close to finished without being nuted to death with MG.

BTW - been growing since 1964 and MG used to be one of the only ones you could buy. Carried many a gallon of the sweet blue green liquid through the desert at night. Nurseries and greenhouses sold more but very expensive. You can ignore the nute snobs. Good luck.

I had to flush the plants today because I'm almost positive they were both experiencing nutrient lockout from soil acidity. I use to use tap water that sat out for 2-3 days, but that causes chlorine to evaporate which lowers the PH. In combination with nutrients and natural crystals the PH was likely way too low. So I'm just going to use water straight from the tap since it has a PH between 7.2-7.8. When mixed with the nutrients it should be within the correct range for the plants. Does this sound logical?
