Conv3rgence Posted October 13, 2015 (edited) A couple of my seedlings look strange, I was wondering if I need to pull them out and dispose of them, graft them, or let them be. The white seedling at the middle top, with the fleck of green at his tip. Hard to see but look closely, he's healthy shape and size, but white. Scopulicola, about 3 months old I guess. Still in humidity container, natural light, no bottom heat. The brown/dark green seedling in the middle, next to the others. Ariocarpus Retusus, about 2 months old. Still in humidity container, under fluoro lights, bottom heat still going with a mat. Thanks guys Edited October 13, 2015 by Conv3rgence 1 Share this post Link to post Share on other sites
Berengar Posted October 13, 2015 Graft the white one ASAP!! It's either albino or variageted, and could never survive on it's own roots. Not sure what's going on with the Ario, if it's still firm and healthy, graft it as well, just to be sure. 2 Share this post Link to post Share on other sites
Yeti101 Posted October 13, 2015 Damn right - I don't think I've even heard of a variegated scop! 1 Share this post Link to post Share on other sites
Evil Genius Posted October 13, 2015 Albino or sunburn. If it´s not grafted with a couple weeks, it will starve because it can t produce chlorophyll. Share this post Link to post Share on other sites
Spanishfly Posted October 13, 2015 The Ariocarpus - a darker green than its compatriots - just natural variation. Share this post Link to post Share on other sites
nut Posted October 13, 2015 Mate what sort of mineral substrate have you got in there? Share this post Link to post Share on other sites
Master B Posted October 13, 2015 (edited) Mate i think Eg is onto something with the sunburn or at least some sort of hyper-sensitivity. I get these reasonably often in batchs of seeds( maybe my germination technique needs tweeking ) Had this happen with a couple of crosses but they all came good. My thoughts follow the previous thoughts... Graft it anyway... Nothing to lose everything to gain☺ Here is a pic of zellys scop x red grandi cross( this one was very kindly donated to me Edited October 13, 2015 by Master B 1 Share this post Link to post Share on other sites

Evil Genius Posted October 13, 2015 Master B, heat damage can look like that too. It´s pretty typical that heat does not kill all the seedlings, so it happens that you sometimes have lone seedlings in between the healthy ones just turn white and turn into mush after that. I mean, if they already look white when they germinate, it´s probably an albino but heat, sun and chemicals can cause the same. 2 Share this post Link to post Share on other sites

Change Posted October 15, 2015 sun and chemicals can cause the same. Which chemicals? Share this post Link to post Share on other sites
Evil Genius Posted October 15, 2015 (edited) Change, fertilzer for example. It burns the seedlings away like acid if the concentration is too high. And if you apply alcohol in too high conentrations (such as 99%). it can kill seedlings. Old plants are usually fine but whenever I spray my seedlings with methanol, I reduce it down to 50%.
