Is this Nitrogen toxicity? The new leaves look glossy/shiny.

no. They look good to me.

Thanks for the response.

I didn’t really had the glossy leafs untill recently. Are you sure it will be fine? I’m going to make a new batch of nutrition solution tomorrow. So that if it gets worse, I can change my solution asap. I only have 1 week of grow left before I flip them.

People are generally happy with shiny leaves. From memory, I only see them in organic substrate. I can't see your video. Is it soil or compost? I'm trying to build myself a picture. I suspect urea is the common denominator, from my own plants

It’s hydroponics.

the oldest leaves are dark green (had a rough start). The newer ones are nice and bright green. And the newest growth is a little darker green with a gloss on them. Where they start growing, and split from the branch, they are a little yellowish but not a lot.

how come you can’t watch the video?

here is an imgur link.

you’re going to need to delete the space in the link. The website deletes my link for some reason…

Looking like cal-mag may be the answer. I had some light discoloring as you do but my plant is larger and more mature, i added a smallll amount of my flower booster and massaged into top soil and I watered, its been getting better so i now know that was cal mag deficiency.

Thanks for the reply.
I got a few stills from the video this time. My connection is terrible. I often can't load this site at all.
Are you having cold nights? Or just went 12/12 perhaps?
The growing tips look a little small, and as you say, a light green. The shiny leaves have a washboard appearance. These are things calmag may fix.
I don't see excess N as I look at the newer growth.

Thanks. I will add some calmag asap. Calmag deficiency is common in hydroponics to the point that a lot of growers add extra. So this might be it.

I didn’t add extra calmag to my first solution. Only the calmag that was already in my tri-part nutritions. I did add it so my second batch. And the solution that is in the system is now around 60% of the first and 40% of the 2nd solution. The plants only really started drinking/eating the last 10 days (the point that I saw the water level drop with the naked eye, on a daily basis). And they have gotten a grow spurt since then. pH is also rising pretty hard. But that’s to expect when not using silica and RO water.

Buffering the RO with tap is usually a good idea. In a harder water area, just 10-15% tap usually adds the hardness we are looking for. Use the filters waste if you can. It's stronger, and you have paid for it.

Our plants tolerate a very wide pH range before showing signs you can see in a snapshot. Slow growth comes first.

My tap is 0.8EC. Still 15%?

Also, as response for your earlier comment. my Light schedule has been steady for the last 2 weeks at 16/8 and niggt temps never went below 20 degrees Celsius.

What do you mean with using the filters waste? What filter will have minerals?

 

[Aqua Man]

no. They look good to me.
