Looks like a deficiency to me. Double check your temps and humidity to be sure, but I'm thinking that's not fungus.

The last few days I had 3 plants start not looking so hot. The 3 pictures are the 3 plants when I got home today. I haven't really encountered deficiencies, if it's even that. I'm watering at 5.8 and last I checked the runoff a 2 days ago it was 6.8. Any ideas?

Check out my week 7 update for more info. Only one plant in the tent affected so it's really bugging me?!? Thought it was overwatering. Left them 2 days between feeds and they are bone dry and pots are light. Any suggestions or could it just be a trait of the Pheno?

I added a couple pics of what looks like rust spots on the leaves of only the tall plant in 7 gallon. I’ve given these two plants the exact same feeding so not sure what is causing it.
