Hello and welcome to the end of week 4, this will be the last veg week before the flower. I have been doing daily LST trying to keep the plants down, in doing so I accidently topped a Runtz, yikes, I guess we'll see how she competes with her sister. I've never topped an auto before so this will be a good learning experience. I also nipped a few bud sites way below the plant. The extraction system is now fully functional, I wired it into a fan speed controller which was a bit fiddly but I managed it in the end, it's running at 3/5 the speed and is a lot quieter with no motor humming. Raised the light to 80% power and about 3/4 inches up. A lot more nutrients have been introduced, brown areas developed on one of the CK due to me holding back the PK I believe. I've switched Root-Juice to plain old liquid kelp so I can get through my old bottle and save some pennies. I added some epsom salts for magnesium content, normally I would apply it as a foliar but I just added it to my feed bucket, I will also be applying a foliar later this week of some of the biobizz feeds and more epsom salt. I had just applied this feed before taking the pictures today which is why they might look a little parched. I am still waiting on my other grow to finish before I move 2 of these ladies out to free up some space, I'm really hoping they'll be ready by next weekend. Thanks for looking
