The first 3 pictures are from yesterday. The next 2 are from today. I just started adding nutrients yesterday. Picture of my schedule so far. PPM after adding nutes yesterday was 238 and measured 247 today so I added some fresh water to bring it back down to 217. I haven't checked the PH since I'm using Advanced Nutrients PH perfect Sensi Grow A+B

You need to be checking the ph of your res just in case it’s not perfect.

Your ppm is to low. Don't go below 400. It needs an adequate amount of nutrients to properly balance the PH.

What LED do you have and do you have airflow around the plants?

I use a Maxisun PB1000 and I have single small fans at 3 levels in my tent. This is an autoflower so I don't think I can go up to 400 PPM yet

Up to you but especiallywith tap I can say it needs more nutes to balance the ph better.

Can prob back the light off to 30" until you figure it out.

Have the roots hit the water yet?

PH is about 7.5 but as long as the pH stays between 4.0 - 8.0 the nutrients are being taken up just as well as at 5.6 according to AN.


I never heard that before, I think the range in DWC is supposed to be closer to 5.5-6.5 pH. I don't believe anything from Advanced Nutrients. Good luck!

Roots are in the water. Looking healthy and white

Yeah then its a nutrient issue imo. I would definitely be backing that light up though... they will go south fast under higher lighting until you get it fixed. Imo should bump the ppm to 400 but that's up to you.

Maybe pics of the roots to be sure?

You running sterile or live?

It still seems to be getting worse. I don't think I trust this Advanced Nutrients PH Perfect. When I first put the nutrients in the PH only went down to 6.4 and now 4 days later its at 7.5. The PPM has risen by 10 from 425 to 435 so I assume that means its drinking water but not taking in the nutrients (nutrient lockout). I really feel like I wasted my money on the Advanced nutrients. I wish I knew what was going on. Growing plants is supposed to be a stress reducer lol
