Hey al how many clones do you think i can do sog style under a 150w hps in hempy buckets? Without sacrificing yield of course. How about under a 250w?
Rethink the hempy buckets. The hempy design leaves roots submerged in water- I'm not a fan. Flood tray based systems are not much more complex and don't have this design fault.
A good rule of thumb for HPS is 50W/sq ft. You can do up to 4 plants per sq ft
IF you diligently prune off all branching on the lower 1/3 of the plant and any that are more than 1" long, in typical SoG fashion. Prune off branching at end of wk2 & 4 or more if needed. I don't think I'd mess around with a 150W HPS. You can get OK results with a 250 but a 400 is much preferred for a small grow. Bud density is dependent on light intensity and a 400 has a lot more of it.
im droping the night feeding, was just hard for me to understand they could go that long without. and there in RW cubes
when these signs started i was on a basic GH feeding program and the burn apperence started my ppm was 1000
and it was sugested to try lucas, problem seemed to go away but as you see its still there im at 800ppms now.
il put up some new pics
The plants stop transpiring water when lights are off. If you water during lights off, water in the rootzone can stagnate (lose all dissolved O2) before the plant starts to shift it again at lights-on. Burned leaves are never going to repair, in case you're not aware of that, but if roots recover, the plant may begin growing again. It's pretty close to dead now and probably won't yield well. Doff the Lucas stuff, go back to GH instructions for flowering for your next batch.
i would not trust my city to provide me with the right amount of nutrients for my plants. if u use an RO system, u KNOW u have a baseline of zero(or very close), and can add however much nutes u NEED accordingly. if i were to add nutes to my regular tap water, wouldnt it have a ton of Ca and Mg in it?
What city are we talking about? Mexico City? US & CDN muni tapwater is universally of a high standard. I can't think of any exceptions.
Ca & Mg are essential micronutes and if they weren't there, you'd have to put them in.
basically what im saying is regular tap water isnt that reliable. u dont know exactly how much is in it. so adding more could cause problems
Not true at all, if we're talking about 1st world municipal water treatment systems. Conspiracy theories about water quality don't count. If you're curious about what's in your water, have it tested and know for sure.

so they do look better but theres still this issue with the tips curling up
and the edges yellowing/browning?
OK, those pix look better. Any reason why you didn't post your latest pix in your last post? The tip curl and margin burn still suggests some NPK ratio problems.
Al,
thanks for the reponse. I was wondering what one should expect there roots to look like? Are your roots bright white all along the pipeline or does the Cana nutes stain them slightly brown/red? My res is kinda redish from the part b.
Roots should be bright white. Tan or brown roots are dead. There shouldn't be enough vegetable dye in Canna to stain roots. The Canna product I use in Aus has no label beyond 'Vega' and 'Flores' but I suspect the Nth American equivalent is Substra. The Aus version has some yellow dye in the red-capped Part B, but no red dye.
Also wondering if you have made any gains in production? Still about an oz per plant?
Thereabouts, yes.
Pk13/14 still in your week 5 and 6 tray?
Nope, haven't used PK in about a year or more.
I was thinking of changing my set up 12" square pots instead of 6 " round, then toping the rooted clones in order to shoot out two colas instead of one.
I wouldn't do that. The plant naturally produces largest & most dense colas on a single terminal. If you top the plant, it'll bush out and produce 2 smaller, less dense top colas. If you want more tops, grow more plants, up to 4/sq ft.
With double the root space wouldn't the topped plant have the same production as two singles? This would be have legal advantages and also I would only have to cut 30 or so clones biweekly instead of 60. Thanks for your time al, I know it's limited!
If your local cultivation laws make a big distinction between 30 & 60 plants, it may be a compromise you should investigate, but if the penalties are the same in either direction, I wouldn't do it.
