Danatron1987 Posted January 26, 2015 Report Share Posted January 26, 2015 Hi Guys and Gals, OutdoorCoco medium without perlite Canna AB nutes, last feed at ph6.The bottom leaves are yellowing and im not sure why, could it be due to malnourishment? or due to not mixing the coco with perlite and starving the roots of oxygen?Any help much appreciated Quote Link to comment Share on other sites More sharing options...
MrCompletion Posted January 26, 2015 Report Share Posted January 26, 2015 First glimpse Looks like over water. The green mold/moss on your medium hints to me it's been wet for a while. Correct me if I'm wrong. Quote Link to comment Share on other sites More sharing options...

Harvest Posted January 28, 2015 Report Share Posted January 28, 2015 (edited) Should run ph a bit lower. Is it switching to flower being outside? 5.5 then 5.8 generally for coco. Should run some fongarid through there. Is it geting enough sun at the base of that tree? Nutrient burn is generally on the tips of the leaves so should be okay to continue normal feeds. How much a & b are you feeding them? Edited January 28, 2015 by Harvest Quote Link to comment Share on other sites More sharing options...
