Jelly Donutz - Why not?

Strain is going great, 35 days in for the 2 lead plants (Tr-Leaf and Lemon) and 21 days in for JR. Have ran a week now at 18/6 and now will shift to Flowering. The lead plants are ready to go with multiple tops now showing and i project JR will run a week or so behind the others showing. So lets start this machine, the feminized seeds should show true in the next 2 weeks. Plants are sucking up some water, about a quart/day with solid white root balls. I did start Hydroguard proactively and have been feeding twice/week now. No negative leaf signs and TDS is between 350-900. Will start some Tiger Bloom next week. PH has been steady, hanging around the lower end... 5.6-5.7 which i bring up slightly. JR is hanging around 6 and seems to be doing fine. Temps have not been to far from range, a couple cold dips into mid 50s caused some droop, but quickly adjusted. Water temps have been staying around or below 70... all good. Humidity stays between 25-35, which seems to be fine for this tent and strains I have tried. Next weeks update.... 7 days into flowering!
