Discoloring on leaves

Hello to all,
I just bought a grobo and I’m on day 14,
Everything was going fine as I’m using distilled water as recommended, and I also have a C02 bottle inside for better yields, my question now is, why is there a bit of wrinkling and discoloring on my fanning leaves?
This is a purple haze strain BTW,
Should I get Hydroguard? Is this a root problem?
Please help anyone?

Take a picture of the roots.
What is your water temperature?
What is the box temperature?
What is your PPM level?

Several factors have to be measured to see what the problem could be.

Mine did the same. No biggie. The first couple of sets might do it. Then clear up. My water temp is 72 degrees. Roots are white/cream color. I put a small fan in the back over the access door. This helped cool it down a little. Both water and inside temperature. I’m not going to use it unless it’s necessary. Water change every seven days there shouldn’t be a problem. Make sure your pod starts drying out around week four. Just lift it up a little. I rolled a napkin around it and gave it a little squeeze. Worked great. Also make sure you have bubbles. It’s critical. and your unit is at least ten inches from the wall. I’m new too. But I found all this information poking around All growers. Hope this helps :+1:t2::sunglasses:

Thanks for the input,
How do I check the ppm?

Ppm meter? I don’t measure this.
