First Bubble Bucket Grow - Plant Problems

that's the only thing i see as a possible problem. 0.9 is pretty high IMO for a plant that size. but i don't see any tip burn (yet).

how much EC is it dropping each day?

I agree with Rky....that is a bit high for a seedling/transition from seedling to full on vegetative. I think that the high nutes are just an aggrevating factor, probably not the base of the problem though. I have RH that is below 50% and my seedlings do get some twist, but don't look anything close to that severe. But who knows, it may just be too many nutes. It wouldn't surprise me if everything clears up with the PPM drop. Good luck :)
 
Just an update.

The leaves seem to be recovering as far as the drooping goes. I still have some discoloration in the leaves though.

I looked it up and it sounds like it might be a Cal deficiency. Thoughts?

Water's dropping, PH is slightly rising, and PPM staying the same. I think all is good except maybe they need a bit more Cal?

that's usually not good.

and the new growth looks weird to me.

what EC are you at now? and is it still just 1:1:1 ratio of the micro,gro, bloom you are using? what other additives?

Ya, I thought the new growth looked kind of weird... Still at 0.5 EC.

I was using 1:1:1 at the recommended dose and CalMag at 1ml / litre at first, but reduced it to half that when I had my original problems... The leaves perked up, but from what I've read the bleached tips on lower leaves probably means a CalMag deficiency, and the slight yellowing / darker veins could be nitrogen?

I'll upload a pic when I'm home.

I would do a foliar feed with the cal/mg.

and add some water to drop your EC even lower. maybe 0.35. i prefer that the EC is dropping daily just to make sure your plant is eating. a stable EC could be great or it could be nute lockout

I've been checking my ppm using the 500 scale, so 500 ppm = 1.0 EC

I've only seen about a 20 ppm drop per day.

Also, is that not nutrient burn on the tip of the big leaf on the bottom closest in the pic? https://www.rollitup.org/attachments/tip-burn-jpg.4335851/

If your ppm is dropping you need to up the EC a little. If the ppm is staying the same just add the same ppm back. If your ppm is rising you need to lower your EC a bit.

Let's see the roots again in natural light.

No more than 20000 lux at this stage.

With LED I would add calimagic at half the dosage. 5.8-6.0 ph your good.

Tbh I think they are a bit hungry and looks like a cal-mag issue.

Would start at about 300ppm of nutes. Would be approx 75ppm cal-mag and 120ppm from the tap. So EC of about 1. Might sound high but I'm betting you will be close there. Then read the plants like I listed above with ppm going up or down
