hey man loads happened, firstly I believe you're overwatering which is causing some strangeness. Make sure your soil goes dry before you water again - very important. good thing you removed the aluminum should help with air circulation. These could maybe recover, just dial in your watering correctly (every two to three days or water less !) and these should start picken up by next week no problem. good luck man ! 🚀

Hello ! Well it's clearly genetic bro , it started from the buttom to the top of the plants , the heat can't lead to that stranges leaves neither a burn or a stress , you'll see that in 2 weeks all the new leaves will be like that. You can't fight genetic so nothing you can do about it. I hope it will help you 😁👍

Hi @UncleSkunk! Well you learned the hard way that aluminium foil burns plants. The good thing is that only the strongest will survive and recover, but they will need time and much love. At this stage, any other mistake can kill them and ruin your crop, that's why in this situation I would throw it all away and start again from new seeds, I don't like to work for months on a weak basis. Hope this will help, keep us up-to-date and happy growing 👊
