i highly doubt it's fert burn as it's pretty hard to burn with organics. i've been using the biobizz line for a few grows now, with no burn issues. you especially shouldn't have any issues with that application rate.

i definitely think you have another issue.

your plant looks small for 5 weeks. this is possibly related to the high humidity.

not to mention, i'm not too found of your light. have you used this before or seen decent results from one?

I've been reading a lot and started my first grow, and until now I had no problems. Last week two of my plants started to develop burn tips on some of my lower leaves. It quickly spread to most of the leaves, some with more intensity and others with less. I read a lot and saw loads of pictures of problems and deficiencies, but could not deicide if this is a Nute Burn or some kind of deficiency (Potassium?). It's hard Rating: 5
