Hi All,
I was wondering if some of you more experienced growers could help this newb out.
This newb is growing sharksbreath from seed in canna coco with 2 gallon smart pots.
Using canna a/b nutrients with rizotonic at about 500ppm on 3 week old seedlings under a 600 watt HPS with cool tube reflector about 16" from the canopy.
Temperature is a little on the high side at about 90F (30degC) but he is using CO2 at 1600 ppm so it should be ok.
There are three pics of three different seedlings. One is the picture of health and the other two are at different satges of this problem...whatever it may be.
Basically new growth is yellow along with yellowing at the leaf margins of the older growth.
Anyone have any suggestions? Its his his second grow and first time in coco. Plz help. Thanks
