I fed the mazar today, 5ml sensi cal/mag grow (4-0-0) and a half cap of superthrive, also I have turned back on my 4 4' t5s but changed the bulbs to bloom (3500k). The tent temps are 85f day and 71f night, 50%rh. The pistols on the bud sites are starting to grow and I will start bloom nutes as soon as vertical growth stops, maybe next week for the mazar and week after for the sbr's. It looks like the sbr will be about the right height, 26-30in but the mazar will be on the short side. The new accurate 8 ph meter I got has helped me do a better job of controling my soil ph, but I still need my checker for feeding/watering. Every grow is an adventure and a learning experience, last grow I screwed up the bloom nutes by adding too much beastie bloomz so hopefully that won't happen this time. Lights (led's) are at 24in and may stay there for temp reasons until I can get room temps down. I have upgraded my laundry room exhaust fan that I tied into my dryer vent from 70cfm to 80cfm and will install a backdraft damper soon to stop air from going into the dryer when it isn't running.
