yellowing vigorously

[okachobee]

a couple of my girls are yellowing and getting brown spots and i cannot for the life of my figure this out i think its a nitrogen problem but not so sure i just flushed so any help would be greatly appreciated. also am using 400w hps in soil plenty of vent ph is around 5.9-6.2. ive been using 3/4 strength (from recommended amount) earthjuice grow and bloom for about 2 wks now and im in 2wk of flowering.

As your plant starts to use energy to make buds you will get yellowing of leaves. How many leaves are affected right now?

looks like a nitrogen deficiency to me. keep the bloom nutrient levels where they're at, but try raising the nitrogen levels up a bit and see what happens. Also, the pH for your soil might be a little too low. I'd raise that up a little too.

its starting to affect my 4th and 5th nodes but ive never had yellowing that far up before i thought it was a nitrogen deficiency but just had to post and find out

My first guess would also be nitrogen. Flush the toilet dammit!

A ph of 5.9-6.2 should be fine, if you have a kit see if you can get it up to 6.5. The nitrogen might be getting locked out

It looks like it is defintely nitrogen deficiency, a lack of nitrogen is easy to spot; the plants yellow in an almost uniform manner.
