Clearly a Ca/Mg issue. That will curl the leaves upward.

If those were mite problems he wouldnt be asking it would be apparent due to all the bugs and webs....at least I hope.
Bloomin Idiot Reviewed by Bloomin Idiot on . Any suggestions as to why this is happening? Hi, I am new to this. I am in week 2 of my cycle. I have noticed yellow spots on my leaves. Please see the attached pictures. I am using a 400 watt system wtih Miracle Gro potting soil (which I will not use again). I have currently 4 plants growing with the light about 9 inches above the plants with 1 light centered in the plants for the lower leaves. I have not added any chemicals other than today. Any advice would be appreciated. Rating: 5
