Edit: I could have sworn I was in Sick Plants... Working on a first grow and my brainstorm is looking sick as hell. I think its a N defficiency? Its started to affect the inside leaves and some are dying off. Ive already had to pluck a few of the lower branches, so I need help! How do I solve this problem.. Thanks in advance...
not an N def. it would be a lot more yellow if it were and i dont really see much yellowing at all. do a flush and check the plant abuse chart in the stickies. may be a P or Mg or S def. but then again im just goin on memory so check the pics yourself and see what you think.
check your runoff ph...people ALWAYS overlook their runoff ph and ppm...Knowing that is the absolute start to diagnosing mostly anything... I've been saying it alot lately, if it looks like nitrogen def. but is not...then most likely your ph is off causing nute ockout.....or your ppm is waaaay to high also causing lockout. GL
