Matt1208 Posted July 20, 2019 what’d be causing this ? just plain graft stock plant, don’t want to be spreading any disease or viruses to other plants Share this post Link to post Share on other sites
Evil Genius Posted July 20, 2019 (edited) It's either cold damage from condensed water, or sun damage. It's on the most exposed spots on the plant (the ribs), so it's almost certainly environmental. Edited July 20, 2019 by Evil Genius Share this post Link to post Share on other sites
Matt1208 Posted July 20, 2019 cheers, I’ll put it under a bit more cover, could be either frost or water dripping onto it considering where it’s placed Share this post Link to post Share on other sites
