hi from roadcam (formerly the image reaper) ... do not use Miracle Gro plant spikes, they release nitrogen too unevenly, and slowly ... there is a lot of undeserved badmouthing of Miracle-Gro, I used it exclusively for many years with no problems, and great results ... however, I always fertilized by the foliar method, and at half-strength ... now, I just use Earth Juice nutes, which, while expensive, they are relatively weak and mild, so less chance of over-fertilizing ... the foliar method allows fertilizing with very little chance of overdoing it ... the only reason I switched to conventional methods, the foliar spray messes up my Mylar walls ... sucks ... :smokin:
