First time grower unsure here
So I'm growing dwc super skunk. I'm not sure what this is. I'm thinking calcium deficiency, but I'm not sure. She's about 5 weeks old. Doesn't seem to be growing either. I'm using GH flora series and I'm going off the recirculating feeding chart. I didn't transition to flower with the nutes as idt it's ready obviously. I change the res weekly and I keep the ph around 6. Using tap water filtered through a 3 stage water filter. These spots have been there for about 2 weeks now. I thought it might clear up after I did the last res change. But no luck.
Welcome to Percys man
DWC, you got a cooler in the Res mate? The res can get very warm in the summer time and that can be bad for the roots. That can cause this twisty kind of growth.
How warm is the res?
No cooler. With the lights out it sticks around 21 but when it's lights on it tends to get to 22-23.5. So you think it's root rot? I was using a jug of frozen water to lower it. But I was told having ice in the res hurts it. And a cooler isn't in the budget right now.
I wouldnt say its root rot mate, not without seeing the roots lol.
Instead of using a jug of cold water, use frozen bottle of water, keep a few in the freezer, and on in each res, when it melts replace it with another bottle That should help control the res temp a little better.
Airstones and everything working ok, no blockage?
Air stones are flowing nicely. I only have 2 stones in about 30L of water. The roots look redish but I think that's just the micro causing that.
She just woke up. Res temp is at 21.6
