First attempt with coco canna

Hi there plant lovers!!. I started a new grow using the popular canna coco line , I'm in my second week and noticed some anomalies I have not seen before using conventional soil. Please take a look to the photos attached and provide some inputs about the status of this little one. Thanks in advance!

They are how old? Have you fed them? Just coco and perlite right or is it the canna terra 'soil'?

Hi Tazbud.. 14 days to be precise, 70% coco and 30% perlite, . I’m using only distillated water, A+B, calMag, PH under control, feeding every morning. I started to introduce nutrients on day 4, was thinking maybe I waited too much?.
What do you think is the status of this girl?

compared to my first experiences with coco for two weeks your off to a great start. I'm no expert on deficiencies they may be starting to get a bit blotchy? Slightly overwatered?, every day might be a bit too often with 30% perlite? A&B my plants seemed to respond to 3/400ppm canna 100 or so mls each but not quite so early as 4 days..

id say 50/50 over watering and or too early for nutes if so make sure your using a light dosage

Third week and moved the little ones into a 3gal container. Its seems that even when I changed the feeding frequency from every day to every 3 days I'm still seen new leaves developing this brown/yellow non-healthy look in the borders. Started to introduce RHIZOTONIC and CANNAZYM highly suggested.. In regular soil this brownish look is usually associated with calMag deficiencies, not sure how to attack this problem using coco.. Thanks in advance for any suggestion..
