Hey there Dean, so basically you have root problems, you can see from the way the leafs are curling and so on. This is a wierd one, but basically it's from the additive you're using (Orca) . Basically this has a combination of beneficial bacteria, but sometimes when the plant is young and you're only starting to feed recently, what happens is some of those fungi are actually fusing with the plant. As you can imagine this is violent and "painful" for the plant , so for like 10 days it's likely to show signs of something going on below the surface. Hopefully the plant will muscle through, if not you can "cure it" using humic acid or h2o2 . Hope this helps ! 🚀
