hey guys my plants in the last day or 2 have become sick looking hope someone can help my room temp messured at the same lvl of the plants is 80. i'm running a DWC setup homemade using the suggested amount of nuts on the bottle of what i have and some superthrive, water temp is around 68. i do not yet have my ppm tester yet still awaiting the delivery of it, but i figured as my roots arnt sitting in the nut mix yet my ppm should remain fairly stable? and i'm only using a crap ph tester atm while others in the mail also, its giving a reading of about 5.7-6.0 or there abouts. not sure if i missed out anything but let me know if you have any questions. plant A is currently 11 days from seed, Plant B is 13 days from seed... plant A's leafs are all healthy looking (meaning no burnt/messed up spots or anything) but droopy apart from the bottom 2 first set of leafs. plant B's leafs look pefect apart from there cupping upwards and has been a slow grower so far. any help is appreciated thanks guys.
