Flowering issues

[NuttyProfessor]

no the low k will make them bottom leaves fade up lighter green , she is moving some k from there , hence the little pk boost she needs
some bottom leaves that get little light will also turn yellow so don't panic

Edit sorry this will cause death to the outer leaf (edges ) , I THOUGHT YOU MEANT THE TIP ENDS sorry

Thanks

what would be cause the rust spots on the plant in the second lot of photos? That a cal/mag issue or is that the K issue

That is the plant removing the (K) from the lower leaves , these leaves then die off, so this is why you thought you burnt them

 

[NuttyProfessor]

This is why you had the same problem , this strain loves her (K) , you can get raw (k) so you dont have to do the pk thing as its pointless as the p is at the start for roots and at the start of flowering then heavy flower (K) is very very important, this is the health element

 

[TheRocket]

Ahhh, i see now! Thanks for explaining

so today feed some ionic coco for base nutes and should I feed some advance nutrients big bud?

 

[NuttyProfessor]

feed the base with the calmag , is big bud a pk boost or bloom stimulate , you want the pk boost i never use them now as i do hydro super soil , if its bloom stimulate they can drive down (K) levels also , read the bottle if its a big pk then yes add some half strength next feed with your base , get the base in there first with calmag , the cal will help uptake the (K)

 

[TheRocket]

Will do!

Reading the bottle the NPK ratio of big bud is 0-1-3. Plenty of K in there

3.5 weeks in so still plenty of time to pull these round I hope

 

[NuttyProfessor]

you will , when your low on (K) the plant stalls they just stop , they use more k than corn plants , you need more in flower , Im trying to get away from bottle, i use in my soil boiled spinach water in heavy flower with seaweed extracts and banana teas , lol
So far its done me ok

 

[NuttyProfessor]

this girl had slowed way down , so she got the spinach lol 4 days later the buds are falling over. I love doing super soils , you can add what ever you like and when you get a good soil stick to it , im doing my best to do a soil for autos , water only start to finish . last run was good , second looks better , i am on the third soil mix, plants eat better than me
this is not an auto BTW

4 days later

the proof is in the pudding

 

[TheRocket]

Wow they look amazing how long you got left?

I’ve fed mine today, they took about 2-3litres each. Fed them slowly tonight. Been throwing the feed into them lately and not feeding them slowly, maybe part of my issue?

 

[NuttyProfessor]

it says 8 weeks that's next sunday but i think maybe another 2

could have dry spots and salty spots , very likely , coco has to be slowly fed and then you will see less run off,you think its fully watered when you water quick , once you have it soaked good and proper , you can water a bit quicker to get a proper run off ,

 

[NuttyProfessor]

I bet your pots feel heavier too now with the extra feeding its holding

 

[TheRocket]

Hey nutty, would you be worried the leaf haven’t perked Up? Almost looks like over watering issues

 

[Stunned]

You can't over water (with nutes) coco

 

[NuttyProfessor]

they will perk up they needed a good soaking , you still feeding daily ? look like the need a bit of air around the bottom
