First off, this is my first post, so how's it going? Second, I am having problems with my ladies. I will first give a slight description of my setup and I will then mention the problem and the things that I have done to attempt to better my ladies. My setup consists of 14 plants, with the tallest one as of late being 47 inches tall. They are being flowered under a 12/12 schedule, at least for the next week, and then it will be 11/13. My lights are one 1,000 watt, one 600 watt digital , and one 400 watt. The 1,000 watt and 600 watt lights are both swtichable. The temperature rarely gets above 82 I have blueberry, power plant, and two unknown plants strains. I was fertilizing with a high hitrogen Jamaican bat guano, once to twice a week, with an occasional flush with a diliuted h2o2 solution.I water 2-3 times per week as well. I also have a temporary homemade CO2 setup, with the water, sugar, and yeast recipe found on marijuana.com. That is the basic setup and what I have done. So my problem is this: My leaves are yellowing and dieing at a rapid rate, and my plants are not producing like they should, especially the Power Plant. Also my branches are droopy, and it isn't because of the weight of the bud. I have checked the ph and it is very close to where it needs to be. THere is more than enough fresh air and air circulation, since the setup is in my room, I have the door open all the time, not to mention the fact that I now have an air conditioner to maintain the temperature. I was fertilizing, as I mentioned before, 1-2 times/week. Then the leaf problem started, so I started using another organic fertilizer with some N, but that didn't work. (I failed to mention before that I have spents hours upon hours reading cultivation literature, and that this is my third indoor grow, with a failed outdoor grow). It just keeps getting worse, and to add to that by branches are really weak feeling and they are soft, not hard like they should be. My plants should have at least twice as much bud as they have now. I have racked my brain trying to figure out what is wrong with them and I just can't figure it out. So, here I am asking for ANYONES help that has extensive knowledge about growing.
