Saxonanswered grow question 3 years ago Bugger, I thought so.
There's also 3 different autos that were also in the rock wool and then went into a good soil mix that are also going yellow.
Oh well another lesson learnt, 3 more photo seeds have now been started, so new diary will be started.
"1st autopot grow" take 3.
"Canna coco professional plus" was used with a 30% verm/perlite mix.
Thanks for your help everyone.
