That was going to be my question. The runoff numbers you have for soil are below my 2,000 ppm (EC 4.0) trigger point for water only. You are in the low end of the sweet zone now for salts in soil IMO. Definitely upping nutes would be good.
That said, plants in flower are going to start to show deficiencies as plant devours leaves. You will see things on lower leaves that look like a def (and they are) but really just an old leaf. The light color you see shows interveinal chlorosis which is a sign you need to supplement with cal mag. I see you are giving 10 ml/gal: keep it up as high intensity lights make plant calcium hungry.
Humidity sensors and gauges don’t last forever, they slowly deteriorate over time and need to be tested 2-3 times a year, that’s why the sensors are able to be replaced in better instruments. In the case of the Inkbird, I cut a notch in the Tupperware container on the lip and lid so they line up and put the sensor inside…put the salt slurry container in there, put the lid on, and sealed it up as best I could with plumbers putty. It worked great and I got a good reading the next morning. Then you make your adjustments from that reading. In the cigar world, this is basic maintenance…same thing with long term storage of musical instruments that need to be in perfectly humidified conditions. What we do doesn’t have to be that exact, close…+- 2-3%…is fine.
Should I be adding calmag to every watering and feeding? I’ve been adding calmag on water only days to this point, thinking of adding some calmag tonight with the feed.
Water night last night.
I fouled up when I was reading my notes before watering.
Went ahead and gave them a feeding of 1/2 strength trio when it was supposed to be a water only night.
Was on a water, feed, water, feed schedule, but went feed, feed, now will go water, water the rest of the week.
Feel like an idiot, but what’s done is done. I’ll see how they handle it, but they looked great this morning so fingers crossed.
Water going in:
1/2 strength trio
1-6.6/1270
2-6.6/1260
I water based on runoff. If runoff numbers in soil are above about 2,000 ppm then water only until it drops. If soilless I use somewhere around 1,000 to 1,200 ppm (soil buffers differently).
Water night again last night. The girls got 1/2 strength week 9 @1.5 gallons each.
Water going in:
1-6.4/1010
2-6.5/1000
Water coming out:
1-2 solo cups of run off
5.9/1950
2-3 solo cups of run off
6.0/2150
Things are going good, I did a little defoliating last night. Not much, just picked a few here and there.
The smell is amazing though! I can’t get over how much stronger these smell than my other auto grows. Fingers crossed I get to the finish line with these two.
Here’s a couple pictures from this morning.
