Yup, your right. Your suffering from one of the most common problems new gardeners have, overwatering. Remember when i said in your first thread i think. Water until it comes out the bottom and then let your soil dry out, well almost. If you lift your pot up and its really light, then water. Mould happens because your not letting the top of the soil dry out. If your soil doesnt dry out youll be giving your girl swamp like conditions. They dont like that. You can get root rot and shell die. This is a good thing that this happened now because youll probly listen to this advice and itll never happen again. Roots like it when they have air that gets to them, thats why ebb and flow works so well. Air time. Next time you do this add some thing that doesnt hold water like pearlite to your soil. It will drain better so you can water more often without having a swamp, a LITTLE more often. The pearlite will make it drain faster but overwatering is overwatering no matter how good your soil drains. Also dont try and keep water in your tray. Ive seen water in your tray and unless you just watered which you may have, thats not such a good idea. High humidity, poor circulation, organic mayter in soil, high temps, low light to soil, and dark periods can all contribute to mould problems. If you want to do somthing about it, take a tablespoon and scrape off the top layer of dirt as far down as you can get without destroying any roots and replace it. If you can get some perlite great, if not, f it, just dont forget to let them dry out more and you should be just fine. Also dont mix the mould deeper into the dirt if possible. Thats really great seeing those little hairs comin from her landing strip. On the big girl too,congrats, lookin good. Cant wait to see the buds!
