Dropy leaves and top laves are shut toghter, help needed

Im 6 weeks into veg
I use coco as medium giving canna a and b as base nutes with rhizotonic and calmax

Night temps 62F day temps 74F

Leaves have become dropy and the top of the plant leaves are shut toghter this proplem happened over night after I wattered and they have recived some low ph wattering for 1 day ph was at 5.4 corrected the next day to 5.8 I cant figure out the problem any help will be much apriciated

auto pots--- nice man, I was lookin into those a while back. How to they work? Do you dose the water tank or let the coco dry out, top feed, then straight H20 from below?
How and how often do you water? Just straight canna coco, no perlite added in? If not you most likely have a slight overwatering. let it dry out some. Other that that if the PH is good now then thats a plus, but keep an eye on the PH, and sample test if you have to in between watering. But 5.4 is not terrible, now 4.5 that's different. You can goes as low as 5.0 in coco, but a comfy 5.8-6.0 is best.

It really looks to be overwatered.

Hey thanks for the reply, I think it was may be becouse I added extra nutes, may from not concentrating innuf I added of something again made it double, or it cud have been over watering, but I dont think it was over watering because, what I did was flush em abit with some fresh nutes mixed water with a full doze of rhizotonic and today they have almost fully recovered,

The autopots they are the best thing that happened to me, made my life so much easier,

I use canna coco with 2inches of clay pebbles at the bottem of pot then add pure canna coco no need to mix any thing with your coco, coco is so airy anyway u dont need nothing,
I use canna a and b, rhizotonic cal max for veg, mix everything in a reserve with a air stone in it and the mixture is good for over a week, no need to do nothing for a week only lift the light so often and always check the ph in your reserver and maintane it at 5.8ph give or take 0.1ph, and all the strains I ran so far every one of them girls loved being in the autopot system, I swear by autopots, best metherd to grow hasleless lol I sound like a sales man hope this helps

Cool Beans man, I'm for sure gonna pick up at least 1 auto pot now. And I have always wanted to give Canna a run, lots of members swear by Canna fertz and their coco. Glad that the lil lady come back around for ya.
