Hello I have 7 plants in an aeroponic bucket that are mostly doing well except for one that just isnt happy like the other ones. They are 2 weeks into flowering and all look great except this one. They are under a 1000 watt mh. Temp ranges from 66 to 77 and humidity ranges from 58 to 68. I use ro water that is ph of 5.8 and GH flora series nutes. My ppm is running at about 1000 using equal parts of the 3 flora series. The roots look just like all the others. Please help. This is my first grow and I am growing for a medical mmj patient that needs meds. Picture one shows the sick plant and pic 2 shows the tops of the others in the same bucket. Thanks for any help.
