this is my 1st grow ever. I got the Purple Haze seeds from an Amsterdam seed bank. there about a month old and a inch high. Am using Moisture control potting mix with 4 spikes of plant food for my 8 inch pot and 2 for the smaller ones. I was watering 2 to 3 times a week witch I just found out, thanks this site. I was making a mistake. I was worried that the leafs turning yellow,hopefully no serious damage has been done.. I'll keep up-dates here along with photos..And any advice is greatlly welcomed,
