Can you go back and see if you can find out what kind of soil those plants in the photo are using? And maybe how often they are watered? And how hot is the room.....wait......here...

give this to whoever posted those pics and have them fill it out..

Weedhound Reviewed by Weedhound on . hello, leaf problems I saw on some plants... Hello everybody! I "found" those pictures on the internet, and I wonder what could cause this illness. The plants are "probably" growing indoor and they "probably" only get water and some special compost made from warms. I "think" they are growing with 2 Fluo lamps on a 16/8 basis, on soil. Your help will be appreciated. Rating: 5
