All leafs seems to be affected by a strange discol...

hey man see how the leaves are going bumpy and a bit dark green / glossy ? could be tiny microscopic pests that are crawling underneath your leaves. they're impossible to see with the naked eye, but what happens is those little pests crawl underneath your leaves and such out the magic plant juice from the leave's veins. Spray with neem oil and a tiny bit of soap solution, or get a couple of foggers and release them in the tent. These pests are very resilient, so honestly there's not much you can really do, but you can try to save them. hope it's not that, but just in case check with a 70x or better microscope and see for yourself. good luck man. 🚀

Honestly, it sounds from your post that you just added some nutrients. Not sure how long ago that was. To me it looks kind of like a Calcium Deficiency. If you just added it to the mix, watch he new growth and you should see new leafs with no issues. Unfortunately any leafs with damage already will remain as they are. I think you may have taken care of the issue already.

Hi @BigMaker! It looks like your plant is suffering from pH fluctuations. You should grab a pH-pen, and double check (and refine) the pH of your solution each time you feed/water. If you don't solve this quickly, leaves will turn yellow and the growth will be stunted. Hope this will help, keep us up-to-date and happy growing 👊

Hello , it's look like a slight over feeding to me , at that stage the plant don't need a high amount of nutrients and even if you divided your nuts amount by 2 I supose that the pre-fertilized soil + nutrients input may have cause this little over feeding. If I'm right then 2 or 3 watering with only water before the next feeding could solve your probleme. I hope it will help you 😁👍
