Plants turning yellow

'm wondering if anyone can help me on why my plants are turning yellow so quickly.

I'm on day 21 of flowering.
I have 3 different strains. Super glue. Ghost og. And Gelato.
Only the super glues are turning yellow.
I'm using hydroponics multiflow greentrees 2 gallon bucket system.
4x4 Rockwood covered in hydroton.
Ph is 6.4 in my reservoir.
I use a 3 part micro grow bloom. king kola , emerald goddess and honey chome products from emerald harvest.


Should I pick all the yellow leaves off ?
Also can anyone tell me if the buds look OK size for it being the start of week 3. Should they be bigger?

nitrogen def

your flowering nutes are low in N

youll need to give me the NPK % ratios for each of the bottles you use for fert. and how much per gallon in mls your using of each in order for me to help you figure out the best way to raise your N

next grow consider feeding veg nutes the first 2 weeks inot 12/12

while your at it you might as well give me the calcium and magnesium % amounts also

ph 6.4 is on the upper end

nitrogen is less available at higher PH

first easy thing to do asap is to lower your ph to 5.5 and keep it low to allow more N uptake

Micro is 5-0-1
Micro says 7.5ml per gallon.
I use 4ml per gallon.

Grow is 2-1-6
Directions say 2.5ml per gallon.
That's what I use

Bloom is 0-5-4
Directions say 8ml per gallon. I use 4ml per gallon

King Kola is 0.3-2-3
Directions say 8ml per gallon.
I use 4ml per gallon

Honey Chome is 0.5-0.5-1
Directions say 8ml per gallon.
I use 4ml per gallon

Emerald goddess is 2-1-4
Directions say 8ml per gallon.
I use 4ml per gallon

isn't it normal for some of the lower leaves to yellow and die off during flower?
I would remove the yellow ones and carry on...
maybe some cal-mag plus?
am a rookie... listen to im4satori.

edit;

is that the general hydroponic 3 part your using?

or is it emarld harvest or both brands combined?

because your using so many products that are contributing to your formula

I think youd better give me the calcium and magnesium and iron info for each also

otherwise its hard to know were to give more or less

I don't want to assume its like the genral hydro line in every way and give you some bonk info

not trying to hijack your thread but am watching this because i have a similar problem, unlike yours, the tops of mine are unusually yellow and looks like we both around the same flower time.
waiting to see how this turns out.

it looks like you could simply bump the micro up to 5mls per gallon

that adds 15ppm of N... and itlll up your calcium and iron which im guessing you need

but I still think you should let me work out your calcium/magnesium numbers because I suspect there off maybe

if its the very top of the plant and its new growth

its either lights too close

or iron def

if its yellowing from the bottom fan leaves first its nitrogen

iron def shows up more often in early bloom (first two weeks) which I believe is from the addition of bloom nute P

P and iron compete for uptake so too much P too early can block the iron and often the problem resolves in later flower when the P needs go up

you might consider feeding veg nutes for the first 2 weeks of 12/12 since the P will be lower it might help with both issues

you could take a picture of the % amounts on the labels for the grow micro and bloom

and a picture of the plant so we can make sure we got it right

They're supposed to yellow towards the end of their life. If they're not ready to finish just yet. You've either got to feed them some more nitrogen. Or maybe you've got a pH issue causing a lockout of nitrogen.
