Burnt Tips

hey there Plan1 , my idea is that it's too many woodchips and too hot a supersoil, usually you want to mix your supersoil with unamended soil first to get it right, then add woodchips in layers, being extra careful not to go over the 50% mark. That's because geting that close means you're actually growing in soiless not soil , meaning you do need to supplement with calmag despite your best efforts. Try epsom salts as a spray for example if you dont want to go the calmag route. everything else looks fine to me growmie, just a bit of magnesium deficiency as the plant needs it more with such a heavy light schedule. Hope this helps growmie ! 🚀
