White rhino 4 weeks & 4 days (31)days into flowering and plant is going all yellow

Hi Guys

my plant is now almost 5 weeks into flowering and i can't say its been smooth sailing as this has been a problematic grow since day 1. Anyway things have been going well for the first 4 weeks of floweing with the buds growing really well but now the entire plants fan leaves are going yellow BUT at least the bud leaves are still nice and green. I know it is normal for the leaves to go yellow and fall off as the plant sucks up the nitrogen....but is it normal for the plant to be yellow as much as it is at this stage with 4 weeks to still go???

so my concerns are the plant wont mature...

will the bud leaves be enough for the plant to photosynthesize and provide enough nitrogen till the end ?

below are the pics i took this morning with the plant at 4 weeks and 4 days (31 days)into flowering.

Some info
pots are 6 gallon pots

lights are 600 W HPS

nutes are
*biobizz biobloom on the one day
*plain water the next
*then black strap molasses on the 3rd day
*plain water again

so the above is my watering schedule with a day in between that schedule with no water, so watering every second day basically with 1 litre per feed

any advice will be much appreciated

You should be fine bro. The yellowing is normal. I think youll finish just fine. However you might wanna give it a half strength dose of your grow nutes just for a little bit of nitrogen to get her through till the end. Up to you tho even if you decide not to i think you will be o.k.

add some chicken shit to the equation.i had the same prob. with the rhino.only plant to have to pull early because she was committing suicide at 7 wks.
