Closet Doms in Water.... An Ad Hoc Log of Black Dominas in DWC Hydro

They are a delightful medium/dark green so I am happy that they are happy. I am gonna add the LK at the first top-off (when it gets at least 1 gal below where it is now). The roots from the first BD grow were alot more brownish from the LK so I'm not even worrying about it at this point...

DOH! Forgot the link... here it is y'all.....

Checked them and both were running high on PPM and PH:

BD1 was at 1520 PPM and 6.7 PH
BD2 was at 1518 PPM and 6.7 PH

Not sure exactly what has happened, but maybe the Dunks had something to do with it. I adjusted them both by adding RO water and Down:

BD1 is 1345 PPM and 5.7 PH
BD2 is 1342 PPM and 5.5 PH

I'll keep an eye on them and see if the PH/PPM creeps up anymore. Gotta run and reposition some shoots and trim back a couple of big honkin' leaves that are covering bud sites...

sounds like they are starting to burn......

Yeah, you may be right. I am trying to keep them below 1350 PPM and see if they respond, as there are no visible signs of over fert so far. If they don't rebound I'm adding another gallon of RO to each of them tomorrow...

When my ph starts to climb....quickly and it seems to to take more ph down than usual to get it back down I start thinking about being at the edge of nuteburn. . This is just my personal way of checking my own plants so don't feel I'm passing on some big secret.......may not work for you at all. ;)

This is the first time I have witnessed a significant climb like that in my hydro days, so I'll take this tidbit of knowledge and see how it plays out in the next couple of days... thanks for looking out for me amiga!

BD1 drank down about 0.50 gal of water and the PH was 5.7, PPM 1393.
BD2 drank down a little more than 0.50 gal and PH was 5.4, PPM 1411.

Added RO water to bring them back to target level mark in each res (currently 3.5 gal), added 14 drops Up to BD2, and here are their numbers heading into their night time (dark from 9am - 3pm):

BD1 = 5.7 PH, 1321 PPM
BD2 = 5.7 PH, 1312 PPM

For me....ph is my biggest key with this.....it will tell you before any other signs of problems. (But....sometiimes the f*cking ph just goes weird.....:wtf:)

Way to keep an eye on the plants MVP! :thumbsup:

Almost forgot to add that last night I removed the last of the undergrowth from beneath the screen and pushed a bunch of fans leaves down below the canopy to give the shoots more light. It appears I am done removing growth and getting ready to flip to 12/12 within the next week and a half or so. I have been running an HPS under an 18/6 light cycle for the last 10 days (I don't have a MH conversion bulb for the ballast).
