Spider mites..... Bummer...... You are another victim of these fucked up creatures. Can be very hard to get rid of. Read up on them here - lots of information. Take action now! They breed like crazy... You can smoke those fuckers if you have too... just more protein.
They are territorial and tend to pick on the weaker plants. Look close at the other plant for single strands of webbing... They are on that plant too more than likely.
I've gotten rid of spider mites three times. Used a LOT of different methods. Some work most don't work very well if they are intrenched like your plant is. I found No Spider Mite works best but it's very expensive.
I'd spray both of them down each day with "water" using a 1 to 3 gal. bug sprayer - Then spray the dirt around the plant with bleach to kill the ones that run off with the water. Continure each day till you harvest them. I didn't want to spray anything on them that I had to later eat or smoke. That's what I did to save 25 plants. The mites ate the shit out of the plants. Would have gotten 3 pounds - instead I got 12oz.
Wow 12 oz is a huge loss compared to three lbs...
I had cut the other plant down today and trimmed fan leaves and cut every bud off individually for the drying rack..
There was no sign on that one and these are the only 2 I have flowering in this room..they were autos.
My mother is also in this room.
I cut off the two big top Colas that were showing the webs and took them outside and gave them a very aggressive trimming. I made them into cones pretty much.. cut off all excess leaves and then some. Didn't want to waste em, between the two branches there was at lease half an oz.
I'm glad that these plants were so far along before this happemed. I will have them cut down in the next 3 or 4 days completely.
Thee 2 plants were in a 50 gallon rubber made bin recirculating with a waterfall inside and a water chiller so no dirt..
stay smokin'
