Something is off...I thinking after Reading some s...

Those droopy leaves are the sign of either over-watering or under-watering... and if you go by what m0use has given you to tell the difference, you'll know what you have to do... Personally, I would also be dropping your pH as Hashy said (and those pebbles have nothing to do with it)... get it down to 6.0, MAX 6.2, especially in coco... Good luck!

Hi mate I have grown one of these in the past and she was the most thirsty plant out of the grow. I'd be tempted to water Ph 6.0 until you get 40% runoff and test the Ph of the run off and Ec. I would also give her 4hrs dark period because plants could do with a rest. As far as your nutes your at about the right strength, autos normally don't like a high Ec. Ec 1.2-1.4 seems to be about as much as they would normally take but I did find mine handled a slightly higher Ec of 1.6 if my memory serves me correctly. Before choosing an answer it's always best to check through the people's diaries that are trying to help you as some people are trying to win a competition and give you any old bullshit to win the point. You don't need to select my answer as I'm not competing in the competition.

Looks thirsty to me. Top water and you will see her perk up in an hour or two. Happy Growing

High Chopdaddy, The plant is really thirsty and she needs water! You can solve this problem with 2 solutions. Solution 1 is to use a deeper bucket at the bottom. You want the bottom 20% from the pot getting water and not just the very bottom like you are doing right now. Solution 2 is just feed her from the top manually. For now just water from the top manually with 10% from the pot volume and she will recover in just a few hours. After that you can think how to improve the water system that you are using.
