What ppms are you keeping her at ? Started flowering yesterday my ppms are around 500. I want to up it roughly 100 a week, till I settle around 900-1000.
Are we using the 500 scale or 700 scale?

I'm still using the 700 scale cause that's what I'm comfortable with.
I don't ever get anywhere near that range. When lights went out about tonight, I was sitting at about 370 (or 0.528 EC)

When I do rez changes, I feed fairly aggressively but she gobbles up a bunch in the 1st 12 to 18 hours so the rest of the time it's lower. I've been mixing rez changes at around 490 PPM (or 0.7 EC). 30% or so of that is CalMag and the rest is nutes. Using RO water.

I'm not sure what scale I'm using. Newer to growing. I didnt know there was different scales.

I usually let the plant tell me where to keep the ppms. I check them every morning and keep a log of where there at. I was just curious what you keep your at.

Your plant does look killer. Cant wait for updates.

My last reservoir cycle did not go all that well. I had dropped the calmag from 2 ml/g to 1.5 ml/g and also reduced the nutes a bit. I ended up with some pretty severe deficiencies - magnesium primarily. Word on the street is that Kush's need a ton of Mag...I believe it now.

I'm now on 4 day rez change cycles and yesterday morning was the next change. In anticipation of severe PH drops, I PH Up'd right before lights out to 6.1. When lights came on, PH was at 5.1. YIKES.

After thoroughly cleaning the rez and inspecting the roots (which are perfectly healthy), I mixed up a fresh 10 gallons and went heavy on the CalMag - 50 ml's.
I used my same portions on the nutes, for the most part. As usual, she gobbled up 15% of the PPM's in the 1st 12 hours and another 15% in the following 12 hours. I've done 3 top-offs since the change. The 1st two included nutes and calmag but the 3rd only included calmag. I'm expecting the PH Drops to begin tonight - we'll see. I'm being a bit more proactive and I'm trying to narrow in on exactly what she's eating...especially in that first 24 hours.

At any rate, we're 36 hours after the rez change and she looks nice and happy again despite some of the largest fan leaves looking banged up with mag deficiencies. My next scheduled rez change is Saturday morning and I'll reevaluate - I already think that 5 ml's/g is a bit much and 4 might be the sweet spot. It's unfortunate that CalMag has as much Nitrogen as it does. If and when I do hydro again, I will likely stop using bottled nutes and just make my own.

I have quite a few pics and will have to spread them out over 2 posts.

(These little babies on the bottom of the 1st picture are really coming into their own!)

With the 315W CMH on top, canopy top is 7 degrees higher than ambient. With the 600, it was more like 10. The top row of LED's are obviously contributing to this as well.

As of right now, canopy temp is 77 and ambient is 70 - perfect. I had been keeping the ambient temps around 75 and peaking at 77 without realizing the canopy temps would be that much higher.

As far as RH, I'm trying to follow the VPD charts but I'm too scared to let the RH get up into the 60's. If she wasn't as dense as she is, I would consider it but I'm just not brave enough to try. That said, I keep RH between 45 and 55%. Canopy RH seems to be about 5% less than ambient but I need more time to monitor to be sure. I may be able to let ambient RH rise higher than I currently am.
I stay from 58-65% all the way through flower. 74-77f lights on and 67-70f lights off. All the time. No leeway for big unplanned swings cause that’s how you get dew which causes the fungus problems if paired with inadequate air circulation.

Just treated her to a fresh rez change...she always loves these :) The calyces are starting to swell but the trich's are all still clear for the most part. Taking her at day 73 still seems like a pretty good guess. Nothing else too major to report so we'll just get right to pictures. Two of the closeups are from branches at the very bottom just to show how uniform everything is. I also took shots of body from all 4 sides. The 1st 10 pics are in this post and the remaining 5 pictures are in the next post (cant post more than 10 pics per post)
