So I’m growing in a 4x4 tent with two electric sky es180 v2 led lights a 4 inch carbon filter and inline. one 14 inch fan to circulate air. I have 3 granddaddy purp and one Hindu Kush. The GDP were fem seeds and the HK reg. I just ending week 3 flower and I noticed a musty smell a few days ago when I opened up the tent and it has progressively gotten worse. After a closer inspection I did see a few leaves on the HK that had little white specs on them but nothing on the other 3 plants so I’m fairly certain it’s coming from that plant. The other three are very healthy and haven’t stopped growing and I’m really impressed with them and the HK has been growing but I feel is a little behind. From the start the HK had extremely large fan leaves and the tips have been dropped from the very beginning but just the very tips of the leaves. After seeing the white specs I did a full strip of the large fans in hopes of getting it more air flow but the smell has gotten worse. I haven’t watered in a few days and I’ve been tilling the soil to dry the pot out just in case it was to moist. I’m growing it in a 5 gal fabric pot. When I till the soil I can get down to almost the bottom of the pot and I’m not seeing any roots about 2in From the side of the pot all the way around. My temps range from 77-84f and as far as I know the RH has never been above 40% I’m not seeing any more white spots but I’m extremely worried about the other 3 plants. I wanted to pull the plant out and quarantine it but I don’t have a spot for it. Any advise will help tremendously I’ve been growing for about a year with just a handful of harvests but never ran into this before. Oh also I did place another small fan on the floor in hopes of pushing all the old air up and out. I don’t have an intake I just leave. I did manage to get a pic under the scope of what I found on one of the leaves. Should I roll the dice and keep trying or just cut my losses and get it out of there to save the others??
