Help plz bro guys 1st attempt at dwc 2 x critical orange punch autos
Qbs Samsung 301hs
DIY dwc totes air 60lpmsplit between 2 totes
11l square pot 2/3 rds hydroton fabric membrane then Coco top third then sat in 24l totes water about 4 inch deep
Veg+bloom nutes e.c .5 pH 5.8-6.2
Water temp 18 degrees
Ambient temp 21-24 degrees
Rh 30-40%
Help please guys plant on left 5wk today plant on right 4wk today do they look ok ?? The younger girl has good root showing I've always grown in soil and my girls usually pray, these girls seem to be on point size wise but I've yet to see eitherof them pray and they seem very droopy does anyone agree?? Lights go off in 4 HR could they just be tired??

Yes, the plants look too droopy.
Their dark green leaves with downward curling tips indicates too much of something, food, light or both.
Your EC = 0.5 seems about right for that growth stage (maybe even a bit low), assuming correctly calibrated ppm meter.

I'd double check ppm and pH meter calibration then raise the lights a few inches to see what happens.

Correct feeding is the easiest part of DWC.
If ppm rises from day to day, plants are drinking more than eating, so reduce ppm.
If it falls, plants are eating more than drinking, so increase ppm.
Once ppm neither rises nor falls very much, optimal feeding is underway.
Then start lowering lights very slowly, while paying careful attention to leaf health.
Too much light will make leaves look unhappy.

The good news is that these plants can take a lot of abuse and still yield well.

I agree, should look better and agree with Simplicio.

For me, if leaves are not looking good, always something off in the root zone. Incase you missed it in the last post, make sure your meters are calibrated properly.

A dwc head on afn says my system won't work I've copied a pal who grows photos this way And hits ten a girl without fail,they looked ok until yesterday parameters all ok still so by my thinkin only Change is in size so with th growth could water level be too high I've lowered it last night but still no change really new growth looks too light on left hand girl??

 

[Dosmokethereefa]

Still no change should I do away with the Coco next time and just start in a RR or grodan and use hydroton I'm about at pullin point and goin bk to fabric pots and Coco

You know when you say " these plant" did u mean DP or autos in general ? I drilled some holes in the pots and shove airlines in and they seem to be on the mend

Roots do like the extra oxygen bro. So that was a good move

Has to be ec/ppm to high and/or ph off imo. regular hydro for me ~1.3ec/~700ppm. not sure if dwc prefers much different.

Just saw this is coco & dwc, don't think I have seen it before, pretty cool. Knowing nothing, I would use the numbers I said above, at 5.6-58 ph
