Nutrients CannabisMingus' Grow Dots - Coco - Autopot experiment

[CannabisMingus]

can get away without pH'ing if my TDS is this low.

That's what I do but please remember that this is my first run with this methodology so time will tell. I just want you to be aware there may be some risk. So far so good but you never know.

Are you all pH'ing your water to 5.x? My RO water is usually around 7, so wondering if I should use pH down to bring it down to ~5.8...

I ph mine to 6.5. Im in hp pro mix.

Right on. Next year then!

hell yeah brother. Are you going?

I am! My son and I are going and meeting some guys I previously met at the 2021 Autoflower Cup. Should be a good time. We'll catch you at the next one man.

Nothing to report other than vigorous growth.

Man that thing is blowing up! Looks excellent.

I think this is a Mg def. starting to accelerate. I upped CalMag to 90 ppm and added 1/4 tsp Epsom to res (at about 5 gal). to bring total TDS of res to 120.

The photos don't adequately show the Mg def - there is significant interveinal discoloration. (I know - i need a new f-ing phone). Also, I turned off Autopot last night and did weekly Recharge top water this morning. I will turn Autopot back on this afternoon.

Is there a specific reason you went with 90 ppms of cal/mag and then added some epsom? I pretty much did exactly what you did but I only used CalMag to 120ppms on mine

I did not want too much Ca. I'm guessing here but didn't want to add Ca if I wasn't seeing the need. I didn't want to go full bore MgSO4 because then I am jacking up S. So I just split the difference. Another way of looking at it: I was spreading out the excess among two different elements, hoping (guessing) that it reduces the risk of Ca or S toxicity.

Make sense?

Interesting to watch. I remember we discussed the osmocote ferts awhile back. Question - do you normally use recharge in the amounts you are using it with this grow?

No - I usually do it approx. 4x a grow in living soil (water only). I don't use it in DWC. Something like mid-veg, early flower, mid- stretch, 3 weeks from chop. Something like that.
