The burned plant has small amounts of new growth at the bottom of the plant. Not enough to seem like it will significantly increase yield in three weeks (see for yourself in the pics above, you will notice small new nodes along the branches.)

Here are some pictures of the more healthy-looking buds on this plant. As I mentioned there are no fan leaves. Please try to gauge if this is ready for harvest. I have read some guides but my lense is not good enough to tell the composition of trichs.

Thanks!
