I've got 8 LA Confidential going, im pretty sure i have all of my conditions dialed in now. My temps hover around 75 degrees at all times, i put a humidifier in the room and am maintaining my RH at close to 50 % . My lights are always kept around 20 inches from the tops of the plants. I have been swinging my ph from 6.3 to 6.7 each feeding. Im using Earth Juice nutes and have a good feeding schedule that should be supplying all of the nutrients i need. My well water tests at 190 ppm. I do have a light buildup of whitish green stuff around the screens in my sinks and kettle. Lime or Calcium? Anyways, since only a few plants are showing any signs of stress im thinking i have a case of a few very weak plants. I made a bad rookie mistake and when germinating in paper towel i let it dry out too much, a few seeds actually had their taproot shrivel up.. After adding water those taproots seemed to come right back to life though so i planted them. Not all taproots shrivelled like that. Now im thinking those plants are the ones that are showing different signs of stress. I've got one plant with a lot of leaf edges curling upwards. I've got a couple plants that even though they are still somewhat heavy, the leaves droop.. Even after watering they still droop some. Then i have one single plant with crazy twisting of the leaves, maybe it's weak and showing stress from fluctuation in the ph? Anyways, obviously i won't be cloning any of those plants, should i get rid of them or just flower them and watch them closely for any signs of hermies later in flowering? I've got some plants that are just happy as hell though and leaves are all great and perked up towards the light.. Im just hoping i have one or two healthy plants that are the better of the pheno's... Here is a few pics of some stressed plants, and one of the healthy ones.. Although they are showing signs of stress, the plants remain almost all 100 % green and healthy looking besides the stress..
