My first big plant, starting to have issues.

I have been growing sog for about 2 years now. I decided to try a bigger plant, here it is.

Strain: Cherry Bomb (seed)
Vegged to 24" topped a bunch of times as a mother
Day 21 of flower in the pics
49" from top of soil to top of bud

5gal smart pot
FFOF
Fox farm nutes at about 3/4 strength
ro water ph'd around 6.0
1000 watt air cooled light she shares with 4 smaller plants

Sealed room
co2 1200-1300ppm fuzzy logic
temps days 80-83 degrees, nights 70-75
rh at 53-62%

I noticed some yellowing today in the leaves. (pictured) About week 4 is where i start losing control. Can anyone see whats happening in the pic & point me in the right direction? Thanks in advance.

I'd cut back on the nutes a bit.

What is your run off ppm

I wouldn't change anything bro, unless there is a lot more yellowed leaves than what you showed. A few yellow leaves on a big plant ain't no worry. Your girls look nice. Having said that you might be at the edge of what they will take for nutes.

I am going to save my self some typing and agree with spliff and bubba

she looks great but on the edge of being over fed
keep up the good wook

Your plant looks fine and you know it, your just trying to show off how cute she is.

Thank you everyone. I always start loosing control and get yellowing around week 4 of flower so I thought I would get a jump on it and ask. I flushed them real good last night and gonna try to cut back on the nutes. 1 small plant out of 16 turning yellow is one thing but the big one I don't want to loose control of. Thanks everyone. I'll post more pics if I see it continue.

Pic 7 is nute burn, pic 6 is deficiency starting.
I'm surprised it's not worse if your PH is only 6.0

why would ph of 6.0 be an issue thats around optimum range.....

Listen up, OP....Why are you looking for troubles when you have none?

All you PH nuts... He's growing in soil... so forget the PH wackyness, it looks fine to here.... Anyone who advocates checking PH run off in soil really doesn't understand...

PH Soil... Seriously a waste of time, if everything looks as good as your plant...

Why would you flush, you have not over nuted/ferted.... flushing your plant, wtf you want to hurt it more?

If the flushed one looks worse next week [more yellow, start adding nutes full strength for 4 more weeks]

You take the word of others and jump the gun and stop the feed? Your plant will starve and start eating it self, leaves will turn more yellow and you will know the reason why......

Seven days after the flush.... just you wait...
No nutes for seven days... after you flush...
Seriously, why?
Is this what you are going to do?
You just washed your soil... think about it....
Anything good [NPK] down the drain.... poor roots...
Then the next thing you do is more plain water...
Why are you making the plant starve?
Think... I'm not feeding my poor plant...
Seriously think about what you are doing....
Are you thinking? Logic... Think logical....
Your plant needs feed now doesn't it?

Some people have to learn the hard way.

my advice Is to pull those discolored leaves off . fan leaves fall off and dye in flower on big plants. I have to go pick off leafs all the time . as long as the leaves near the buds and the buds look healthy you are good . its normal to lose fan leafs during flowering in larger plants. some people will tell you to push nutrient harder or less. im telling you it looks great. keep doing the same thing you are. and let it go until your completion . I grow 6 foot tall plants. in doors. this is what I see. all the time. so chillax they look great.

I flushed because I was thinking I was getting burn from to much nutes. That's why I post the question in NEWBIE section

My plants seem to start sliding downhill around week 4 so I thought I'd get a jump on it but if you guys are saying she's cool then I'll just keep down what I'm doing. Thanks.

OP, your plant looks beautiful, be proud of that lady. That yellow looks like a bit of N deficiencies, but nothing I'd be over concerned with. Plants will rid themselves of leaves from time to time especially larger plants, but she is looking fine.

pH 6.0 is not optimum range for soil. 6.4-6.5 is.

-spek

Yup 6.0 is a bit low. If you had some dolomite lime in it i wouldnt worry so much but you dont. Dont change a thing but the ph and ph it to 6.5
looks good though!

Dunno how big your container is but looks a bit small, root bound plants will show deficiencies i would think this definatley the problem
also as stated it looks like u have a lil nute burn, remember higher temps will cause plants to drink more than they need causing bad nute burn even when there is low concentrations of nutrients.

I didn't know this. How would you prevent this from happening if even lowering the concentration & it still burns?

It's in a 5 gal smart pot.

Lower your temps, can be done a few ways, get bigger fans, intake from outside, raise lights, air cooled lights, A/C

Use even lower nutrient concentrations, if you think you plant is burning just add water no nutes.

Also if you have a fan pointed towards your plant the leaves close to the fan will dry out, and especially quick if humidity is under 35% this could cause plant to drink more even when temps are fine. humidity can be very important and prevent a wide range of problems.
in flower keep your humdity wayy down. humidity is one thing many people overlook and will grow faster and healthier in correct humidity

i personally use a 25gal for much smaller plants than this, I think your slowly killing your plant when its only got that much space, you'll probably see your plant health deteriorate.

but Dont transplant now its too late just remember next time roots like space to grow and is better to have a pot too big than a pot too small as your experiencing with that round bound plant.
