Deficiency OR Excess of Calcium - How can I know?

[SpecialChoban]

Ok, will try to correct the CAL - MG deficiency,

Thank you for all the help!

Hi all,
another weekly update.

Updating the situation with some photos.


Right now I am feeding them with:
GHE Micro - 1,3 mL/L
GHE Gro - 0,65 mL/L
GHE Bloom - 2 mL/L
That gives me EC in range from 1,1 mS to 1,2 mS.
Sometimes I am adding 0,65 mL/L of ATA CALMAG.
Combined it gives me EC reading of about 1,3 - 1,4 mS.
I am apprehensive about foliar feeding them CAL-MAG at this stage.(Bloom)


The EC in the tank varies from 1,3 (when topping it off) and 1,1 (after 24hours).
The pH also varies from 5,9 when topping off, after it drops to around 5,5 - 12-24 hours later.

What do you guys think, should I try increasing EC? Decreasing it? Should I leave it as is?
Does any1 have any recommendations? (all kind - some improvements to my setup?)
Anything is very much appreciated.

Thank you.

hope this aint a stupid question,
did you soak your pebbles, i think you have to soak in ph ed water as well, (im not 100% )
someone should say for sure

I can answer that easily - you should rinse them thoroughly.
And yes, maybe even soak them - to get all that clay off.
It really depends on the product - some have more clay on them some have less.

This round I only rinsed them thoroughly. And I can tell you that doing only that - it wasn’t enough.
I think in most cases you should soak them in you normal tap water. (overnight/24 hours)
And after that rinse them thoroughly, so you get rid of all the clay. (clay dust)

In my case, with only rinsing them - my pH was spiking for the first 2 weeks - so I changed the whole reservoir more often for first 3 weeks (replacing reservoir water 2times a week),
so I was able to stay inside the 5.5 to 6.5 pH. With time the system stabilised - pebbles got rinsed inside the system (with top feed) - not ideal.
I am sure, that some products need more cleaning and others less (pebbles).

So yeah, lesson learned. Soak you pebbles overnight + rinse thoroughly.


p.s.
It is not a stupid question - very relevant indeed.

Cheers!

hows your going mate, any updates

[SpecialChoban]

Sure, thank you for asking.
Will put some pictures right here:



Under the lights (ON):



Added a few more small fans (4 to be exact - in each corner - light breeze around Buds - should help in making the flower bigger)
My EC ranges from 1.3 to 0.9
pH 5.5 - 6.2

Like I said before, this is my first grow - so I am not sure if I am maximising my yields properly.
Some of the flowers seem to be at least a week in front of the others.

Nothing else to report. If anyone has some recommendations - would greatly appreciate.

Cheers guys!
