i planted my new purchased seeds 3 weeks ago. I used rockwool to get me started.
First thing I did wrong was over water as I had the rockwool sitting flat on a plastic lid so I had no drainage. When the first set of true leaves came up I transplanted. I noticed that the root was coming through the bottom of the rockwool and started to grow sideways as I had the plastic lid under..
I transplanted into canna clay balls 18l air pots, then the next day I removed and filled my pot with 1/3 clay balls then the rest with canna coco. I did rinse the clay balls overnight in 5.5 ph tap water. Unfortunately I did not do the same with the coco.
The leaves were a bit yellow and dropping. Then last week I fed them with the recommended nutes after not watering for 3 days. That's when it all went down hill, I noticed the tips were becoming burnt and crispy whiteish. I then flushed with just a tiny bit of canna root stimulator and ph 5.5 water till I had some run off.
The prob seemed to get worse in the last couple of days, I haven't watered since that flush 4days ago. The leaves are not dropping anymore but are developing burn spots on leaves.
I have searched the net and can't seem to find the exact symptoms I have.
The photos make them seem healthy green, in fact they are actually pale green/yellow.
Can someone help me before I make things worse..please, cheers.
