Ok thanks
Ec rising IN RESERVOIR

It's way easier to use regular bleach than pool shock. There's even more sodium in Pool shock compared to most sodium hypochlorite based products since lye (sodium hydroxide) is used in the manufacturing of both. Bleach is intended for cleaning and sterilizing while Pool shock is only intended to sterilize.
My local brand of bleach (sodium hypochlorite) is about 90% pure compared to HTH which is often not more than 65% pure since it's intended for sterilizing pools and not cleaning floors etc. There's also bleach based on calcium hypochlorite but I've never seen that in real life and I would check all the data before using any new products.

I would add 3ppm to everything going in to the reservoir(new res, top offs etc). I use big water wessels like 8 gallons jugs with cap to keep the chlorine from dissipating. I think that's the easiest thing to do.
Ok thanks I'll stick to that. 3ppm NaClO added to everything

I don't use chlorine much, so I'll have to trust you.
Hi, they seem to do better although still some signs of not well-being. Ec was stable for 2 days now and ph only rose a little (which is normal I guess).
Please take a look at them and tell me what you think. Is still something off or is this just recovery?
The leaves are pretty light colored not to say almost yellow, right?

They are top feed. Do you mean I should have used coco instead of clay pebbles?
What do you mean by water to run off?
I don't think we have the same type of deficiency/damage right?

go watch the videos below dude- so simple to grow, people over complicate things- have not grown the way you are for a very long time far to many headaches .....
So you are essentially saying that I should switch away from pebbles?

I posted the same question a few months ago. Had to resolve it through the process of elimination. My problem ended up being a nutrient that I used had gone bad. I am using Jack's 3-2-1 formula and the Part B of the Jack's that had been stored in my garage had gotten damp because it was in a cheap plastic container. I didn't think it would matter & being as cheap as I am I didn't want to throw it out even though I literally have a lifetime supply of the stuff. I am so damn cheap that it bites me in the ass many times.

Looks more like Mg def to me. Very common with high intensity LED's. What light do you use? It's better to let the plant grow in to the light then aiming for closest "highest optimal intensity" and measuring light distance, every plant response differently. They don't need much to flourish in veg, just enough to keep stretch and internodal length down.
ok thank you that could be it.
I in fact use high intensity LEDs from Luminus. I can increase the distance.
I have about 300W for the space you already saw many times here. 1.5m x 0.9m (5ft x 3ft) is the size of the tent but I think that they use up about 0.75m² (8 ft²). They should probably put out about 700 - 800 umol/s. More or less even spread to probably 600 umol/m²/s PPFD.
Do you have a target PPFD in mind?
Hi everyone,
Water consumption rose over the last few days and EC went down from about 1300 to 1200 μS/cm for the first time in weeks. Ph is about stable around 5.9.
But the deficiency/symptom seems to progress. Updated pictures attached. 4 pictures of the plants, one for each. And 4 pictures of close ups of damaged plants.
@Wastei I pulled the lights back and measure about 500-600 μmol/s^2/m PPFD which should be pretty low.
Ca. 25°C temperature
Ca. 60-70% rel humid

They seem to respond well to the treatment then. They gonna look worse before they get better. All the yellow leaves are going to fall off. Do you feed 15 min 5 times a day? I'll try to aim for most of that feedings during lights on and only feed enough to keep the Hydroton moist throughout the day and night.
You need to circulate that system pretty often to keep them happy. Impossible to overwater in Hydroton/clay pellets, it's the water being stagnant that you don't want causing the roots to be unhappy. Keep feeding nutrient solution with oxidizer(bleach) and they will improve, there's a lot of roots that need to be broken down and removed by the circulating water. Hope that make sense, Cheers!
