Mini 16 oz Aeroponic Setup

9-3-20 Beginning week 3 Growing faster than the reference plants that are in the cups and I think are 4 days older. Room was in the lower 80's, kept the door open and put a fan in it. Got the room down to mid - upper 70's. Been battling aphids for a year now, tried a couple sprays and applied Sevin once. Anyone know any tricks? 9-7-20 The pH was up to 7.1. Corrected to 6.5. A burned leaf tipped me off. Despite the pH being off so much it is growing much faster than the reference plants or it's siblings. The root growth has exploded. There were a few roots protruding thru the stainless screen in the bottom of the cup. Screen is 100 mesh or maybe finer. I'm going to have to find something to prevent that. 9-8-20 Another burnt leaf. Lowered pH to 6.1. TDS about 411. 9-9-20 More leaf burn. pH was 6.1. assume I have too much nutes. Recalibrated my TDS meter, added a gallon of distilled water to bring TDS down to 250. Adjusted pH to 5.6. Still growing like crazy.
