Hi

I wonder if you guy could help me ID a problem?

Set up
Hydro ebb N flow
PH 5.8
Canna softwater Nutes (should be well within ppm range about 500)
H2O2 5Ml/ 10 Litres

basically I started gettign some leaf curl on the ends and sides a few weeks ago with a few rust spots and one or two of the leaves were goign brittle on the ends - I saw this as mag deficiency and possible over nuting (although there were no more nutes than there were at the start) so I added an extra couple of buckets of clean water to dilute the nutes and a tbs of epsom salts for each 10 litres. The problem seemed to be ok then for a while obviously the damage had already been done to the leaves but no further damage was occuring.

Anyway it seems over the last day or 2 the problem has come back, I haven't changed the tank yet and have just been topping with clean water - I added some more mag this morning to see if that helps but it hasn't flooded yet so if anyone thinks this is a bad idea I can drain the tank.

Anyhow I have added some pics and would be really really really grateful for some advice cos I've had nothing but bad luck with this.

Thanks in advance.

Anybody got any ideas please, please, please?

Bump, I'm getting desperate now I think my babies might die, heeeelllllppppp

how long are the plants staying wet? what type of watering cycle are you running i know its ebb and flow and people most do 3 times daily. it sorrta looks like over water. or maybe root rot and keeping out nutes only things i can think of goodluck.

Hi

Thanks so much for the reply.

I have been watering 4 times a day for 15 mins when lights on, same as last time. The only thing that happened last week some time was I over rided the timer and forgot and left it flooding for a good couple of hours but I had a lot of this problem before that.

Any other ideas or comments gratefully accepted.

whats your ppm? how old are the plants? did it strat on the older bottom leaves?

ppm about 500 until I put the epsom salts in obviously the ppm is way higher now.


no i dont think it started on the lower leaves

calcium def and a mag issue.

get some cal/mag, one tsp per gallon

and stop using h202, it's killing your benneficial micros...
love, kp

Thanks KP, really appreciated.

I can't get calmag where I am so I will maybe have to buy calcium and magnesium seperately or am I ok sticking with epsom salt for the mag?

The only problem with not using H2O2 is that when I stop the tank gets all gunky quick, is there anything else I can do to stop that?
