Whats up. My plant has been flowering for 7 weeks. alot of the fans leaves started developing yellowish brown spot and the fan leaves on the top buds have yellow edges\brown tips. Is this normal at this stage in flowering or am i doing something wrong?? All ive been using is Tiger Bloom 2 tsp/gal and molasses every other watering.

Nitrogen deficiency. Probably too late to fix this grow but there's no reason you should ever have yellow leaves in flower after you read this:

You're already in week 7. Its almost done. Definitely do not start adding nitrogen now. Just go on with your grow. Start adding molasses if you haven't already, flush in a week, and harvest the week after that (depending on how amber the trichs are)

Yellowing is natural this late into flowering has the plant needs more of the other elements in the nutreints the nitrogen.Also i used to use mallasess but i use a sugar mix that i do my self now because most shop bought mallasess has salt in it and this could be the cause of the fringe burning..................................tyke.....................................................

Your plant is lacking nitrogen.

If your using fox farm nutes, ..You might as well do it right.


You need alot more than just the tiger bloom my friend.

Good luck :)

2 tsp per gal of tiger bloom is a pretty P rich dose. Sounds like P burn too me. Need pics to be certain. At 7 weeks I would be backing off the food though. Closet I did many a grow back in the day with just Tiger Bloom. And really do not supplement it with much these days. Just maybe a bit of ChaChing. The thing to remember with FF is this. Stay with the Grow Big through the 2nd or 3rd week of 12/12, then switch to Tiger Bloom.
EDIT: Also be on top of your ph, Tiger Bloom really lowers it.

Dont try to fix anything, its perfect, it is just using its stored N at the end of flowering. even if you did manage to green it back up all your doing is making the curing take longer.

I agree with serialkiller. This is common for the leaves to turn yellow late in the flowering phase because you are following directions with cutting out the N in flowering. Your buds are going to be fine & taste great after drying & curing. Don't add any more N & I would only worry about yellow leaves if you were trying to show your plant off like it was some super model bitch trying to get her to win a drop dead gorgeous award. It's all good, your buds will be fine. Don't sweat it !!
