I purchased 10 seeds of Blue Dream Autoflower from ILGM, and it seems to a good start. But the second set of true leaves seems to have a slightly gray color to them. I did add 3 tsp of Mikro-Myco, Highly Concentrated Mycorrhizal Fungi to the DWC reservoir on day 5 when I transferred to the DWC. I was wondering if that might be it.
Also the DWC is a top feeder, the seedling in dry in this photo because the water is being changed, but the leaves are often wet from the top feed.
Currently I am keeping tent at 79 F. Water temp has been going up to 76 F, so I started adding ice packs once a day to at leave get water temp below 68 F for at least a couple hours. I am still researching a “tea” for the higher water temp or just buying a water chiller.
But I am a little concerned about the color on the second true leaves, and it seems grow of the seedling is a little slower than in the past.
Any expert advice on if there is something wrong here? Thank you in advance.
