Tangerine dream red and green garden

Girls are a month old today! 5/26/19 Not much has changed. I raised my ppm to around 850-875. The extra ppm is coming from a few extra drops of flora nova grow. I upped my watering to two times a day. About a liter each plant two times a day. They are 30 days old and ive been patiently waiting for pre flowers. Don't want to rush them but damn. Been fighting temperatures a lil but with research on my leds and in house c02 levels the constant temp of 90 degrees during the day in the grow room isn't hurting too much. Plants are about 18 inches tall with the exception of one thats half the size of the rest. Run off is 6.3 ph at 700 ppm 5 30 19....34 days old What's up y'all. Been busy these past four days. Tuesday the electric on my street went out for 4 hours. I still gave it its normal four hours of dark that night. Might have stressed em good cause the next day i think I'm starting to see a switch into flowering. Confirmation? These girls are getting big. Did a little experiment on the smallest plant in my garden. Kinda wanna hold off on what that was. But i will say i stressed it to the max..
