Indoor BCN Critical XXL, Critical+2.0, RDWC under COBs

[Boradan]

I am running waaaay lighter than the greenleaf site recommends at the minute.

Just did a res change yesterday for the Dinafem Critical+ 2.0 with the following:

Tap Water: 35 Litres (aerated with a 200 Litre per hour pump and golfball air stone for 24 hours)

Megacrop 2.0: 11g
Cal Mag Pro: 6g
Sweet Candy: 4g
Bud Explosion: 3g

That gives me a ppm of 540, although the tap water has 190ppm, so it is 350ppm (0.7 EC) from the nutrients.

According to Greenleaf, I should be using about 40g+ of Megacrop at this stage...

That BCN is some mighty fine stuff. Branches get really thick & Rigid though so hard to LST. But it puts out several Huge Buds about 10" - 12" long & 2"-3" diameter. This was one of my favorites to grow.

I know I am pushing the nutrients way too hard, I'm still dialing it in and figuring out the bloom cycle because MC has a LOT of nitrogen. Do you cut out the MC closer to the end and ramp up the BE? Thank you for the info!

 

[Boradan]

I have dropped the MC from 14g to 11g over the last 2 weeks as she was running a touch Nitrogen-heavy.
BE I will probably up to about 6g by the end

And you will keep this ratio until the end?

how come you sit your water out for 24hrs is it mains water with chlorine etc in it or your own well ?

Mains water with Chlorine.
the 24 hours with an airpump and airstone also gives a dramatic pH shift due to the Oxygen forcing out most of the CO2 already in the water. This has the affect of raising the pH by 0.5 - 1.0. Far better to have that pH shift done before adding nutes or putting the water into the reservoir - I rarely get any pH drift by doing it this way.

would this work something simular for well water for the ph my water comes out at about 6.5 to 6.7 depending on rainfall after adding nutes it drops to 6.2 then i adjust to 5.8 the next day it will be back up at 6.2 or should i drop it to 5.5 and see if it stops more in the sweet spot

Yup, it would work the same.
When I have aerated for 24 hours, I use pH down to get to about 6.0pH and then add nutes/additives and it will stay around the 6.0 mark (a little variation in that depending on the nute strength/ratios I am using at that time).
