Safely Upping Nitrogen To Combat Severe Yellowing During Flowering

I'm in week 5 of flowering, day 32 exactly and within the last couple days the plants have started rapidly turning yellow, even some top leaves. Ive grown before and generally know what I'm doing but I would like to green them up just a little to save the surface area of all those fans for better energy tranference for max bud developement.

I'm using GH 3 part, diamond nectar, likwid Karma, grozyme in the medium of hp promix, ph is steady at around 5.8-6.0.
 
ayone who knows could you please advise me on this? I was thinking of adding a little more grow ( of micro, grow,bloom ) to the next feeding to slightly increase nitrogen... they are turning yellow alot faster than ever before and I follow a feeding guide (tried and tested) to a T
 
The answer is yes. I was advised to add a little N in flowering for that exact reason. I have read up on it in lots of places and lots of people do it because of the lack of N in flowering nutes. From what I was told as long as you are not 2/3 into flowering. You can google adding N in flowering stage. Lots of info out there. Several people here advised me first, then I looked it up.
 
For sure, i veg feed in flower multiple times, like you said, keeping the leaves happy and healthy is really critical for the plants maximum potential to be realized. i give veg nutes like every 4-5 feedings, last one maybe 3 weeks from the end. that whole nitrogen is bad in flower is an old wives tale.

very much appreciate your info dark, will do. btw been awhile since we ran into eachother, Cheers pal hope all is well!
 
Week 5 is usually when i run into deficiency issues as well. Fox Farm chart even shows a boos of Grow big given around that time frame for that very reason. Give them a good shot of N, then back right back off of it.
 
IMO i would give them A shot of super B max 1- 2 -1 ratio as foilage i see you are useing grozoyme good choice yo must have the sea weed based SuperBmax1 available foilage spray your girls an watch her change
 
Got any lime in that promix? With a pH of 5.8-6.0, it doesn't sound like it.

The micro would be your best bet for N, IMO.

no funding atm for absolutely any products but thanks for the tip, I will keep it in mind and check it out
 
EVEN YELLOWER NOW:

Okay day 35 these plants are yellowing RAPIDLY!!! like real fast. I have decided a MASSIVE flush is in order and will take place tonight, with a final dump of 1 gallon of 1/8 strength veg nutes (ph'd) per plant to keep em fed with some extra N. I did some research and believe that alot of the issue is because of huge salt/nute buildup and fucked up PH so the flush will clean then right out, restoring the medium (hppromix) and the small veg feeding should help with bringing back some green. Sound good? I hope this works out well. Any advice is much appreciated! Thanks (remember this is only day 35 with that much yellow within 3 days)

I will update again very soon with improvements in the yellowing fans or no improvements(worse)... I post this shit for a little help from knowledgeable guys, but mostly to help other growers who suffer these same problems so we can learn to combat these issues.
 
Here they are three days later. I'd say they look a little bit better, less yellow after the big flush and veg feed. I'd say it's time to stake them heavy branches soon lol Next grow i will give a manditory good flush right at day 1 of 12/12 another flush at week 4-5 with a veg feed to boost N to tie them over for the rest of flowering. A learning process it is and I learn by the day. Here's before and after, 3 days apart;

if your in flower you don't want more nitrogen usually...u want p..but it depends on your mix of nutes..they may be a bit low on n...yellow leaves can be from too much water..not enuf or too many nutes..in general...start with the basics and go from there...

Actually you are right and wrong. I'm finding more and more that a healthy shot of N ( within a low dose but full veg feed ) halfway through flower is very beneficial for maintaining more fan leaves a.k.a solar panels which in turn creates more energy for the plant to convert to the fruiting buds. This is known by many above amatuer growers and the rumours of a dose of N during flower ruins your harvest is an old wives tale! But.... I wouldn't go to heavy on the N, that's where your right. As for all the yellow being caused by watering, nute issues I think it's mainly just that rush of nutrients( including N) the plant starts consuming around week 5 that causes that rapid onset of yellow fan leaves. I wanna save em' for a bit longer is all. My proof is in the pudding (check the pics, those are3 days apart). Thanks for your comment.

Hey BC Buddy.
I used to run into this on certain strains even after flushing plants every few weeks (in soil).
I started using cal-mag from day one of flowering and this has seemed to take care of any early yellowing.
Peace.

Hey Malibu, thanks for that tip, I will try it on next flower cycle. What brand is it? How much recommended per/gal? every food feeding? (feed,water,feed,water)
