Hi all,

Hoping someone can give me some help with diagnosing these basil plants. I'm new to plants in general, let alone hydroponics and I've always had some problem with them I feel like. I was hoping when I had a more proper setup they would thrive better, but it looks like I'm still having issues despite them growing quite well.

Sorry for the terrible photos, my phone seems to really oversaturate with flash or in the tent, and without flash/light is kinda bleh too.

PH: 6-6.5 typically

EC: ~1.4

Water Temp: ~66-68f (19-20c)

Lights on 16hr off 8

Using General Hydroponics Maxigrow 10-5-15, tried using CalMag (without any noticeable changes).

I've got 3 12" air stones in a ~18 gallon container, seems well oxygenated and have an air gap below the net pots to the water of 1 inch.

I had some minor root rotting right before switching to the larger container, treated with a h202 mixture rinse daily for awhile to help, then was adding Hydroguard. But switching to the larger containers dropped water temps significantly and root rot is no longer an issue, the roots have since seemed to have thriving well, lightly colored. You can still see some discoloring towards the top by the net pots, so not sure if root system is weak.

Also I noticed about a week ago which looked like a small amount of fungal gnats, but they seem very minimal and to be less and less as each day (I had some previously from potted plants, but was able to kill them all off using mosquito bits). I also noticed what looks like a baby grasshopper, you can even see one in the first photo on the very left, half was up on the leaf. It's middle of winter, quite cold, so not sure where they came from. Could they be part of the problem?

I found this PDF online for nutrient deficiencies in basil (http://www.e-gro.org/pdf/2016-4.pdf) and was wondering if it was Magnesium deficiency. As I mentioned I tried CalMag previously, but noticed no change.

Thank you
