ehh, underwatering is more of a droop, like your plants been running in a desert all day and just wants to collapse.

Your plant stems are very, very, very red. If anything only your fan leaf top part of the branches could show red color, but the main stem and the whole plant looks red, the burns have yellowing around some but most it looks like the leaf just died. I have no idea what this is, outdoors = less control. Red stems i understood as the plant storing food in excess, and that it is looking for more of somthing else. more info
JackdaWack Reviewed by JackdaWack on . Unknown leaf problem - BROWN and crispy (pics) I have 4 plants outdoors, which have just gone into flowering as of a few days to a week ago all with varied problems... My first thought was it must have been from giving too much fertiliser, but soon realised it couldnt be; because all plants are varied in the number of leaves that are 'sick' and I have been giving them all the same recommended doses, and the fact that I havn't given them any fertiliser for about a week and a half and they've only been getting worse recently.
