White Widow Auto DWC (First Time Grower)

1/21/2020 Start of the third week! It's growing so fast. Changed all the water and mixed the nutrients today. Four gallons of water this time to try to get the roots to go down instead of wrapping around all the clay pebbles. Maybe I should stop the top feed (drip ring).🤔 1/22/2020 Yay, she survived the night! I'm always worried I screwed up the amounts of nutes when changing the water, but it looks ok. I am noticing some tiny brown spots on the bottom two leaves. And I think that the calcium deficiency so I bought some Calimagic off Amazon. Should be here tomorrow. 1/24/2020 So the leaves started drooping and the brown spots became more prevalent so I decided to change the water again today and add the Cali magic before the nutrients just like the directions say to because last time I forgot to add it and add it in last. I also lessened to the water level because when I change the water on Tuesday the root still hadn't reached the reservoir. When I looked today there were three long white roots growing down hanging in the water. Hopefully I see results soon. 1/25/2020 It looks like it has gotten worse and I don't know what to do. Does anyone have any ideas? Leaves are now drooping with more browning/yellow dots. I stopped the top feed last night because I think I was over watering it now that the roots hit the water. The drooping seems to have gotten a little better but not improving super fast. 1/26/2020 This community is amazing! Thank you everyone who helped me answer my question! You all didn't make me feel stupid and I really appreciate that! Now the update: New leaf growth shows no sign of calcium deficiency. I am now checking the pH level everyday and I've noticed that today was a little high so I lowered it a bit. And the last thing I changed was the light distance. Had a couple people mentioned that it looked way too close for an LED light so I backed it off a bit. I also started LST today. I don't have the rubber wires, but I did have some plant ties I had lying around the house from when I had vines growing on my deck. I'm going to use those in the meantime while I wait for the order to come in. 👍😊 1/27/2020 LST is starting to go well. Leaves look dark with no sign of spots. Added some PH balanced water to her reservoir because I've noticed her roots were drinking lots of water. I pinched the leaves off that showed signs of calcium deficiency. I'm not sure I would count that as defoliation because I don't plan to do that. I just couldn't stand looking at how sad the leaves looked. 😣 1/28/2020 She's looking good. Just topped her today. New air stone and some Hydroguard is coming in the mail. I've been battling stinky water and algae which makes me change the water every 4 days. I want the water to last at least a week so I don't have to worry about it when I go on vacation in two weeks.
