Zkittlez Autoflower

Partway through last week I noticed that there was no runoff after feedings. I increased the time the fertigation pump runs to 2 mins twice a day. It seems like either the root system is drinking up more or the added aeration has changed how much runoff comes out. Plant 1 has fallen behind in growth. The inter-nodal spacing was so tight that the new growth was being strangled by the older fan leaves and other growth. I adjusted the LST to help and pruned a very small amount of leaves. It seems to be doing better, but is several inches shorter than Zkittlez 2 which has had some really explosive growth. I started the scrog today, bending many of Zkittlez 2’s branches down to fill out the tent. I bent a few branches on Zkittlez 1, but it’s still a little short. This week I upped the nutrients, almost doubling the Cocos A & B, Multizen and Cal Mag. I still tried to keep EC down though, only allowing it to rise by about 300mS/cm. This could actually be the first week of flower, but think I’ve started to spot some pistils, but I’m not sure. I can’t find the breeder’s info, but think it’s supposed to have a 4 week veg time and 10 week flowering period. Update: lots of pistils being thrown out especially from Zkittlez 2. It’s definitely the first week of flower. There has been a lot of growth since the start of the week. I continued to bend branches down and tuck them under the net, but now that buds are really starting to take shape I'm going to lay of any further stressing. I noticed that there was little runoff over the past couple days. Yesterday (Monday) I had to refill the reservoir and mix up new nutrients because there was only an inch of water left. These girls have gotten a lot thirstier over the past 2 weeks. I've upped the feeding times to 3 minutes twice a day.
