Deficiencies

HI all,

i´m currently in week 5 or 6 of flower. I have 2 Wedding Cakes, 1 Shogun and 1 Monster Bruce Banner grown in soil.
Light is about 45-50cm above the canopy.
I water every 4-5 days with allmix ferts and my water has a ph of 6.3-6.5 when i water the plants.
The biggest one has yellow leaves with brown tips and edges(wedding cake).
Shogun has overall brown tips and edges and Bruce Banner might have a nitrogen deficiency.

What could the deficiencies be?
I attach some pics.
Thanks in advance!20211122_112840[1].jpg

The big plant is a monster bruce banner. 1st pic of the leaf is a wedding cake. 2nd and 3rd is shogun and 4th one is again wedding cake.
 
Thanks for your answer!
What deficiency has the 2nd and 3rd pic? Is it P too or something like Calcium/Magnesium?
And what is a good way to counter it?
Tried to give it less nitrogen, cause of the dark green leaves and more P, but didn´t work.
My plants get around 1.5-2l of water every 4-5 days.

I would make sure the ph of my medium is in range for proper nutrient uptake first.

Thanks!
Even when i´m growing fully organic?
I´ve read so many articles about organic grow, some say ph matters some say not, when watering the plants.
Could the medium be not in range, when i water the plants with a ph of 6.3-6.5?

plants care about the ph of the medium their roots are in, not what you water with. ph of medium first thing to make sure in range for proper nutrient uptake if suspect root zone issue

Agree that under or over water is something to keep in mind

Ok, so i guess i should water them more and more often?.
One plant already shows signs of overwatering(hanging tips of the leaves next day after watering).
Tomorrow would be waterday for them. Is there anything i should watch out for?
If you guys need any more infos, pls tell me. Thanks!

I can’t say, I’m not with the plant. If suspect overwatered, don’t water till it’s recovered and ready for water

Yeah, done it with the small wedding cake. 1.5l is what she gets every 4-5 days and even that seems too much but is otherwise too less for this pot size.
Guess she might just be a diffcult one.

Ok, i will test the run off tomorrow.

I just put my ph pen in the wet part of the medium, gently, until getting a reading and check several spots to ensure consistency. You are welcome to use any method you’d like, of course. If testing run off, keep in mind all variables.

I like your approach better. I will do it like this tomorrow. Thanks for this simple but very helpful advice.

No it is potassium and forget about runoff pH, this guy is in every thread probably high on meth giving bullshit advices to check your runoff.

Can you please stop that bullshit now? You have your own truth about pH so keep it for yourself. Thats excactly what I was talking about. There is new G asking for help and bitch like you hit his thread sending him to check runoff. Even more sad is you using your pen for liquid to measure surface pH and the real tool for this you saying you have and claiming it sucks. Dude wake up!
