I have successfully grown Autos in the Grobo. @Todd.grobo is correct, they are all over the place with how the grow and react to events.
This is not to say they are bad or do not produce. It is just to say, customer service advice is not necessarily going to be correct. Actually nobody’s advice is a guarantee. Todd is just protecting their ability to be credible.
That is precisely why this forum was created. We are able to ask other farmers who may have some issues customer service does not cover.
With that being said, your seed looks weak. Usually seeds pop and Jump out of the pod looking for light. If your seed starts slow and looks deformed, most would say drop another seed. Weakness may continue and waste precious grow time.
This may be due to the seed lot, something in the water, or something you are adding. If you are not doing anything outside of Grobo nutes, then try again and change the water source.
If the water is pure and good and the nutes are pure, then it has to be the seeds. Unfortunately, we all are subject to obtaining good seeds. I do not know a solution other than pay and pray.
Just my Stoner opinion man. I would chalk it up to searching for a bag and the dude said he had the fire. I waited and waited. Finally drove to him and it was full of seeds and stems…
I cursed but didn’t quit smoking or searching. I eventually got better connections so I could guarantee my exchanges were awesome.
