New grow setup. I have 11 bruce banner feminized in a diy aero setup. Vivosun 4x4 tent, mars hydro ts3000 led light. Ac infinity cloudline series 200 cfm fan and charcoal filter. Advanced nutrients is what I'm going with. They are about 12 days from seed. A few of the bigger sprouts are turning yellowish and sort of brown spots on them. I'm only using distilled water and keeping the pH at 5.7 and PPM at around 10 or less. I haven't changed the water in 8 days. Is that why they are turning yellow brown or do I need to start adding nutes? Appreciate the help, cheers.

Ppm should be at least 100 I'd think, they're dying from no nutrition is my thought.

In coco I give seeds up to 200-300

If you use distilled water you need to supplement with cal/mag..
Yes start feeding 250 ppm

What is your houses water source? If it is town, go online and get a water report. You can take a screenshot and cross out your town and post up the results to see if the town water is OK to use, or if u have well water you might wanna send samples for testing. If u can use tap water it may save a lot of dough.

I ended up getting a reverse osmosis filtration system that fits under my sink. The holding res for it is only 2 gallons so I fill up several 5 gallon water jugs throughout the week to get ready for reservoir fill ups
