Yellow/Brown dying fan leaves week 4-5 flower

[therollingj]

Hey guys, I'm new here, into my first time grow outside. I have some sativas around their 5th week of flowering and I'm starting to experience a lot of yellowing, and dying fan leaves. I'm not sure why it's happening, I'm thinking possibly nutes are locked out, and they need more nitrogen? I'm feeding big bloom though veg, and now for flowering using jacks blossom boost. I stupidly removed a bunch of fan leaves because I thought they were "in the way" (noob error), so maybe that is also adding to the inreased yellowing of other fan leaves.

Any suggestions on what to do and any ideas? Oh and there's a few little peaks of some bud porn too, just to give ya an idea of where I'm at to help with prognosis

hey, sounds to me like the plants are using there reserve energy to feed the buds. You say your using the blossom boost? is that all. boost nutrients usually have high ratio's of P and K but hardly any N. The usual flower nutes you use along side your boost usually contain all the nutrition the plant needs during that stage as well as micro nutrients the boost does just that boosts the plant into making more bud.. you need to get the building blocks in order, a good quality base nutrient Id recommend some biobizz bloom. its organic to so will help the over all taste of the buds. and then continue with your boost. any pics?

There are pics thats what the photobucket link is for. I'm feeding jacks blossom boost 10-30-20. Maybe I stopped feeding my veg sup too soon. I was using fox farm grow big. Maybe next feed I should add a couple tsp of that as well?

Now's the time for FF Tiger Bloom if you are sticking with FF products. FF Big Bloom is another product you can use all the way through vegetative and flowering stages.

I had jacks 10-30-20 I'm using that. I wasn't planning on buying the tiger bloom since I already had this. Jacks has always worked well.
