Sorry not true. Coco is a very easy medium, and add a little perlite and almost impossible to overwater. If u start your baby's with low strength nutes and gradually increase it you won't have a problem. Add a little cal-mag aswell.I use a product called nutri boost , which is a mixture of B vitamins and enzymes. Similar to superthrive. It really seems to give the clones or seedlings a boost of energy. The most important thing is getting a EC and ph meter. Sent from my iPhone using Grasscity Forum
The only thing I would add is to let the coco dry a bit while the roots are growing. This is the only period I find it's possible to overwater. After the roots have grown all big and strong like, you can feed 1-2 times a day without problem. Then that's when you start to see explosive growth. Cheers.
