Any idea what the lighter spots are on the leaves. Plants is an Headband auto from Humboldt. It’s about 3 weeks old from seed to now. Been just water until last week I introduced nutrient and the spots have been visible as it grows. Ph was at 7.5-8 and this week I adjusted to 6-ish. Soil is Mother Earth groundswell PH tested in range of advertised. Temp steady 74 humidity 70. Light is Ac infinity Ionboard S33 240W set at 80% hung 3 ft above plant. Plant seems to be doing fine and grows each day and smells great. I’m am new so I needed help in trying to make it easy so I used a recommended book with a recipe that I’m following I will add the photo also. Trying to make things simple and understandable at first. I have also purchased the cannibis deficiency book and looked at tons of articles and tips but nothing seems to make me feel like that’s the problem I was thinking Cal-mag because of the PH levels. I purchased 3 test kits one being a PH pen the other paper strips and the last ypu mix and shake Mach the colors. At this point I finally feel I have the PH down for the next feeding in a few days. At this point I’m just trying to keep things simple and make a good first run so I can learn and get better. I added pics starting from latest to early to show the issue through the growth. To add I did see today for the first time one tiny and I mean tiny little bug that flies. Not sure if that a concern. I did see it getting blown around by the fans and I did kill it but can’t ID it. I now feel early on I had the light a little hot but it was turned down to 60% and has been at 3 ft for few weeks. Also dropped temp and humidity for earth Veg from 77/70% to 73/65 and have fresh air from the bottom and a fan circulating at te plant and one above near the light.
