Could low humidity cause this?

    I recently came back from vacation to seeing my plants being very underwatered. This about 2 weeks later and the humidity in my tent is at about 38 percent. Is this due to humidity or another problem. This is my first grow[​IMG]

    Could this be a calcium problem?

    that's not humidity...that's "nuked" what's the run off ph? drooping is caused by excess salt buildup And more commonly overwatering and excess HEAT. . .

    Runoff PH was around a 5. I didnt realize the nutrient solution i had was baking my neutral water acidic. I just brought it up to 6.8 and flushed my soil

    that temp is OK..and it sounds like you found the problem..low ph locked out nutrients..in turn building the salts up on the roots which eventually fry the leaves ...6.5 to 7.2 ph...keep the runoff there.and you'll be fine...keep us posted.

    I think I found the issue. Fungus gnats. They have been responisble for my nutrient difficencies and my leaves curling and getting brown spots
