Canna nutes in rockwool and clay pebbles - it seemed to start after being in the same nute mix for about a week and a half - it was dumped after 2 weeks and the nute mix increased to EC 1.2 or about 600ppm as per the bottle.looks burned to me- I could be wrong but we could give a better answer if you give us some details on your soil and nutrients
This is his E.C. 1.2Canna nutes in rockwool and clay pebbles - it seemed to start after being in the same nute mix for about a week and a half - it was dumped after 2 weeks and the nute mix increased to EC 1.2 or about 600ppm as per the bottle.
2 Days before it started happening cheap CO2 was added delivered under the leaves with straws from a big bottle dunno if that could have any bearing?
Also the leaves had been curling up along the sides for some time before this, that with the yellow tips made me think it could be mag. def.
thanks for the help
Firstly, I'm not a hydro grower, I'm a soil grower.Hi thanks
PH is about 5.6
So its a defo nute burn then? What is the solution, flush with plain Ph'd water for a few days then half the nute strength?
I'm more than happy to defer to Kindprincess one this one as I said, I'm not a hydro grower and don't want to give people inncorect advice.On the canna information it says ph between 5.2 & 6.2 so I could lift it up some - would you recommend raising it higher than their recommendation?
Canna Substra does come in two versions - one for Soft and one for Hard water. Do you know which one you have and the EC of your tapwater (or the water you use to water your plants/res)?Canna substra - not sure if e.c was quite 1.2 but I know PPM was around 600
