As you can see in this pic, the leaves are kinda drooping, it's not on all plants yet, but would like to fix the problem before it gets worst. Also I'm getting burnt leaf tips as well. If you look at the lower right side of the plant you will be able to see it. I've never done auto's before, This is my first auto grow. Would you please help me fix this problem. These plants are 49 days old and I use Hydro-Bloom, hydro-guard, Armor Si. I have doubts about TDS meters. With that being said, The TDS meter shows around 850 PPM's. I'm not sure what it should be at. Thanks for anything and everything you can tell me.
