Maybe I should only give magnesium , no calcium... Looked after them and there are just some new spots. So I looked up my tap water, I have a lot more calcium in it than magnesium, so in theory it should help just add magnesium. On the canna mono calcium it says to much calcium will suffer a magnesium deficiency and on the magnesium bottle : to much magnesium will suffer calcium deficiency :rolleyes:
 
Merry X-Mas to all :) :green_heart:

It's getting crowdy in my little tent! :D

Today a little Update with good and some "bad" news - All new leaves haven't any new brown spots on the leaves and look really better now! So I think cal/mag has done something. Only the "old" spots are getting bigger very slow, so I also will add some cal/mag in my water.

Also nice - the late lady is now the biggest - she is stretching very fast!

BUT .... I really would appreciate some advice what going on here, cause the first lady seems to have stoped growing and the leaves are "turning" - last watering was just water and the time before with 50% of the dosis what BioBizz says on there nutes-plan.

I haven't got a clue about the leafs. But maybe it has something to do with the light change? I don't know but it's a guess. Have you tried looking in other threads here? There is a lot of knowledge here, just need to find it.

Hope you find something. I still think they look beautiful.
 
Ok, the light is a bit confusing..
Could you take out plant/ cut just one leaf and take a pic in normal light?
Take the ugliest one.
It is on both high and low growth, right?
Stem is going red?
New growth is healthy though right?
Some things I can see is, that roots probably need more space.
PH must be off somewhere
I can't get the colour of leaf
@Emilya is great I will pm her.

Thank u Angrybird! :)

Light went on at 1 pm, so I can take pictures than without the red leds, then it should be better, otherwise I will take them out.

Can't take bigger pots, these are the max for my little tent....
 
I usually double check the pH with my pen and the drop test... But I noticed that the pH goes up again when I have some left over water... Means I water them on the evening (pH 6,5 temp 20-21°) and in the morning it's like 6,8-7...at the same temp.

When I mix all together I let is sit for at least 2h and give them a swirl every ~30mins. The ph even raises in this stage, so I usually add some pH - to get 6,5 and wait a bit than I water the plants... Is that wrong what I do?
 
Hope these pictures are better - they look a lot better today I think...some turned leaves are now normal, but some are also still turned. And every plant has red stems - but only at those who got direct light, thats what I noticed.

One of the older leaves:

Every picture is taken without the red leds and with the same settings:

These pictures are with more exposure time, otherwise they are to dark:

The "first" big leaves have only red stems, not the hole veins are red, what u can see here
