my plant was healthy but then i let a friend take care of it for a day or so and when i came back to get my plant it had a brown leaf and the tips of the pistols were orange my friend said he put the light to close to the plant and it burned it it started flowering about a week ago would this do any thing to the potency of the plant and the yeild
It's fine. That bud might stop growing from where it is burned but in my experience the bud just grows around the burnt part. My last grow had a huge double bud because i burned it early in flower.
