yellowing is continuing.... i spaced out re-upping calmag at this location..... nxt time, aside form yellowing the plants are growing well, stil had nothing but maxi @ 7 g per gal, upped it slightly to 7.5 to 8 g per gal to try to fix the yellowing, didnt work, so back to 7 and ill add cal mag and or epsom salt.

Damn! One day i have an idea and thro some clones in cups and take them over to Jbonez house and look what i started! I dont even grow vert but think im about to start.

Lookin good Avi

Did you use the same medium through out the tower. J and I were thinking maybe staight coco in the top cup the mixing more and more perilite as you go down. maybe some chunky perlite in the bottom cup

Been struggling with something similar for a while now.

New location, but still RO from a high PPM well, I've been having trouble with both 6/9 and to a lesser extent Maxibloom @7g Gal.

DHF and a few others diagnosed as being cal/mag related so I started hitting with 7g + 5mL/gal of calmag. Think it was a bit too strong however because I almost immediately started getting the claw.

After seeing my Run-off EC in the high 2s I started to flush with 1.0-1.2 (however dropped the cal-mag).. The plants continued to yellow up with various issues. Continued to bump up 1.4-1.6 and back to full strength 1.8, but the issues remain. The buds look great and will finish out, but the yellowing is starting to reach bud leaves which will make trimming a nightmare and leave the door open for bud rot unless I get them down quick.


Clearly I'm not great at diagnosing and sorting problems in coco and the info/experiences of others varies so greatly across the board.

Everyone says run 1.2EC or thereabouts .. however 7G maxibloom alone is 1.8-2.0. I think full maxibloom with calmag on top locked my shit up. I've ran this "dosage" diluted but its hard to say if my problems are clearing up.


I've got purple stems and pale growth across the board...many times looking what I believe it Mg- (the lightening of the leaves with darker veins), but epsom foliar doesnt seem to remedy.

Oddly enough my plants under T5s take whatever I can throw at them and look 100% perfect.



I dunno.. very frustrating. I used to kill it with Head recipe or Maxibloom in RO w/o CalMag, but believe I was running old membranes at the time and think my "RO water" was around 100ppm vs. the near 0 I am running now.



I've used up all my Maxibloom in this location and going to be trying Jacks + CalNit.. both going the route of PPK.. and some handwatered coco plants.

thanks for the input flower farmer, i may try a feeding w just cal mag no maxi.... then go back to maxi.

bulking up nicely, despite the yellowing....




^^seems like the base pots are not yellowing the same as the cups.....
wonder if that is because of my cup colosseum design or due to strain differences... the base pots are def more sativa leaning and therefore may be content w lower nutes...


^^^ untrained verty build-a-tree, imo this one looks the nicest.

Honestly bro I wouldn't sweat the yellowing to much at all.... Now that you hit them with the cal-mag you've done what you can. Just snatch them yeller leave off and pretend they weren't even there... And then go to BK, snag some more cups and build another ghetto tower to thro in there

Have you checked for root rot? If you are getting more water to the top then the bottom and the top are not drying enough to get oxygen to the roots then it could be root rot.

If this is the case you need to change the perched water level. This could be done by hanging a piece of rope from the bottom to wick the excess water out. Poke a hole and shove the rope in a couple of inches.

Just a guess from me though.

I wish I done it that way some of my plants get yellowing as they flower and the one next to it don't
