Something is amiss here

Hello, I am a fairly new grower/patient and i ordered a variety pack of autoflower seeds and a 5 pack of female Gold-leaf and the first problem i had was 11 seeds would not germinate, I’m using DWC and followed all your growing guidlines, I even used a heating pad no good, I tested the water and the ph is okay 7.0 i have a 5’x5’x6’ grow tent, I’m employing 2- 2000 watt LED lights set for vegetation and 1 5000 watt LED light. The 9 seedlings that did sprout were dead within 6 weeks.!


Does anyone know why this had happened? I used to have a setup with 1000 HPS lamp and that plants was finished at 8ft high indoors so I’m thinking perhaps i need another one until said plants have gone through vegetation and employ the LED for flowering or what?
Thank You - Dean

I can’t be sure what happened, no environment information, air pump CFM if any, no water temps, and it could be any single one of those things, or all of them.
I want to help, to improve your grow next time, but there’s not enough information in the post to know what went wrong.

If your DWC pH is 7.0, you need to readjust your reservoir and start again.

5.5-6.0 is the sweet spot and your 7.0pH water is too high.
