M.J.R Blend

Using 4-corners M.J.R blend for first time. Cant find anything on web about it. The guy @ store said very rich in Castings. I have a clone that is extremely Nitrogen starved. I just put him in soil yesterday. Has anyone used this soil? It should be Nitrogen rich so I don't want to add anything to it. If you have used it, how long before you need to supplement nutrients? Also, any idea what PH is out of bag. I watered with 6.5 PH. My Girlfriend said peat was very acidic?

Those are some general questions, I am mostly looking for opinions or fact about this product.

Thanks

I use MJR on my indoor plants... For my environment i find it far superior to FF OF due to the water holding capability. Yes it is very N rich-- definitely wait a full 14 days before supplementing with any N fertilizer unless you notice deficiencies prior to that time. This is awesome as an outdoor soil and equally as good indoors especially if you struggle with high ambient temps. I do add some perlite to the mix before planting but not a lot. I grow organically using Earth Juice nutes

Also-- straight MJR is an excellent soil conditioner. Use it as a top dress to replenish stale soil.
