Yea, no doubt your children are still in dirty diapers. Perhaps too dirty.
The single most important factor of quality growing is what you put your precious little seeds into. Just "potting soil" may not be giving you all your plants need. Check out Genesis Soils, Genesis Soils they have organic compost with worm castings and mycorrhizal inoculum.Dude, their ain't nothin better, I have been lookin for 35 years and this is the good.
Hope this helps!!!
