Dark spots organic

Hello. I could use some advice. I have spots on leaves of 5 out of 6 of my plants. All of them except the youngest. Im growing in a 4x8 tent. Im using 2 sf4000 lights. Im following the manufacturers instructions on distance and intensity. They are in 5 gallon square fabric pots. The bottom 3rd is a local organic super soil. The top 2 thirds is cocoloco. I’m watering with tsp water that has been sitting to let the chlorine evaporate. Its also PHed. They seem to be growing good besides the spots. Any advice would be appreciated. Thanks

What are you feeding as far as nutes? It looks like you have a touch of nute burn.

Hello @detroitpwp3 this looks like a calcium deficiency (less likely manganese) to me you might have to add some calmag to your water or get you something like this, it will help you keep the ph good in your soil as well

I haven’t added any nutes. Besides the water, I sprayed them once with lost coast plant therapy right before dark period a couple of weeks ago. All the seeds were purchased this ILGM

ILGM is pretty good about making things right. @Myfriendis410 can we please get this individual in touch with the right person?

They are in Europe so there is an 8 hour time difference. Be patient and they’ll respond.
