Can drooping be caused by things other than watering

[Olive Drab Green]

So after struggling past an issue of deficiency I am not 100% sure of the cause of the issue that I am seeing.

I have noticed twice that I have drooping leaves. I know that it is not overwatering as I add water (no nutes) and the drooping goes away. The question I have is whether drooping can be caused by factors other than water (ie nutrient excess)? I have been flushing weekly with plain water (to runoff) to limit salt buildup in the soil.

Medium: Coco/potting soil
pH: 6-6.5
Calcium added: yes
Nutrient PPM: 480 ppm
Watering: Blumat System - nutrient drip fed

Definitely water. The leaves look bloated, slightly, and it looks like P/K/Mg have been leached by overwatering (these nutes are highly mobile.)

Your issue is you are flushing.

Seems to be making a difference. I used a little Borax (pH adjusted the sodium salt) with Cal-Mag a little nutrients. Plant slowly recovering. I think I may have had a pH issue before as well. I dropped the pH of my watering solution down to get it in range.

I wouldn’t use borax, bud. If you’re running synthetic nutes, get some pH Up & Down, buy 6.0-6.5 is pretty reasonable.

So things have changed and not sure if too much or too little nutrients.

So my solution has cal mag in it and by the time my water is factored in Iam at 200ppm. I added some nutrients (12:34:12) to bring the ppm to about 450 and adjusted pH.

I don't know if I have a deficiency or excess.

On the borax side maybe wasn't clear. Not using borax to adjust pH. I used 1/16 tsp in 10l water. By adjust pH I meant that borax is not boric acid so a little basic by nature meaning I need to adjust pH to get to 6.5.

Sorry was clear see above post

Noticed the other plant (diff strain) having problem too.

Is this potassium deficiency?

Slowly ramped up to 1200ppm and things improving.
Still learning the ropes of growing and have a lot more to learn.

Looks like sulfar or iron problem

My CalMag has iron so hoping that is ok. I added some epsom salts into the drip feed.
I am sitting at 1000-1200ppm at the moment and things seem to be going a lot better.

Well growth exploded. Buds really put on a lot of weight and the plant looks really healthy. I noted some signs of nutrient excess (dark green leaves). So I watered the plant with straight RO to about 15% runoff to remove some of the salts/excess nutrients.
I then set drip up with a lower nutrient solution (800ppm) and shifted to flowering nutrients. Iam 3 weeks into flower with about 7 weeks to go so dont want to start starving the plants.
