[caseybriggs55]

my plant is about 3 weeks old and some of the leaves on top have begun to turn yellow from the outside in is this a nutrition problem? Or is it a burn problem and how do I fix it?

Pictures tell a thousand words.


There are a number of different types of yellowing top leaves and it all depends how they look as to what's causing it.

Could be any if the following.

Heat problem
Sulphur deficiency
Iron deficiency
Light bleaching
Magnesium deficuency will eventually cause top growth to yellow


So from your description take your pick of solutions

OR

post a pic and get a better response.

Well, no pictures. No mention of grow medium...."from the outside....???" Edge? Tips? Face? You don't say what nutes but you ask if it is a burn problem. So, if you really don't know how to ask, there is your problem. It is a detailed hobby, but I see no attention to detail in this post.

My raw guess is Cal/Mag deficient. But, I'm hoping you can do a lot better with the info.
