New Grower Grass O Matics Auto Mass (sick)

[Autogrower]

Hello and good evening everybody! Well, in my country its evening.

(and sorry for bad english)

I have one Auto Mass in my grow along with some other autos.

But it looks like its getting sick, so i tought i would make a tread, and get to the root of the problem before it gets worse.

I suspect that it is a nute proble, but cant find anything like this around the web.

I dont know if it is nuteburn or defiency.

But i suspect that it is the last dose of nutes causing the problem, its 3 days ago and today i did see some rusty spots, and new leaves are more yellow than usuall.

The setup:

145w LED
2 x 55w PL-L 2900K (vertical)
Soil: Canna Terra Professional +
Pots: 6,5L
PH:6,7


The nutes i have given it:

3 weeks old: 0,5ml Canna Terra Vega on 1L water.

3 weeks and 3 days old: 0,5ml Cannazym and 0,5ml Rizotonic.

4 weeks old: 1ml Terra Vega on 1L water.

4 weeks and 3 days old: 1ml Cannazym and 1ml Rizotonic on 1L water.

So the last dose was maybe alittle to heavy?

Been thinking of not using Cannazym and Rizotonic afterall. Because it looks like the autos are very sensitive to this.

And should i wait til week 7 with the flowering nutes? Is this the case with all autos, or could it be defiency because it has started flowering?

Will also mension that it look stunning healthy until today, and the last dose with Cannazym and Rizotonic was two days ago...Is this nutes the problem?

What do you think?

Thx in advance for all help.

Peace!

is it only on the bottom leaves?

 

[kayden313]

If so i would flush her with plain water the next feed or so to see if its fixed ..if it not gettin any better then it could be mag defcieny and i would add 1/4 tsp of espom salt with the feed every other feeding

Its not on the bottom leaves at all. It is on the top leaves.

Yes PH should be fine. But i dont have epsom salt.. Can i use any of my nutes?

Canna Terra Vega or Flores?


Shure it is deficiency?

The problem is at the top of the plant. Such bleaching is usually due to light burn. Dark green veins, lighter between, is probably Mg, so add some epsom salt.

Ok. Yes could be lightburn. I kept my LED really close, and mayne it got to close. Thx for heads up.

Gonna look for some epsom salt. But really dont know where to get it....
