Im not a noob but i still cant tell the diff between mangenese, phosphorus and calcium deficiency… im not using anything special, just roots original and neptunes harvest tomato and veg. The roots doesnt display anywhere on the bag the NPK values.
they have been pale from day 1. They sprouted on the 10/31 and have been growing quickly

@metaridley your tops look good so even though you have this on the lowest leaf I would not change anything yet…she can have a calcium deficiency when that leaf was growing and now she doesn’t but that leaf was damaged and will not recover

You want keep eye on the leaves above them to make sure it doesn’t go on up the plant

The plant does look a bit deficient. First of all, overwatering can cause that.
Also you said you’re not a noob, so is this soil reused from a previous grow? It could be depleted or contain too much salt buildup from the bottled nutes.
Its new soil. I will just keep an eye on the newer growth.
Thanks so much… this is my favorite strain
I’m growing White widow right now & going through the same thing. Mine is over flowing with branches & leaves. I trimmed the hell out it 1st. Then I read they need lots of nitrogen. So the nutes they get have some but I added a supplement of additional nitrogen. I also started using molasses in the water 2 times week. So the store bought nutes take care of the macronutrients & Molasses covers the micronutrients. Mine are doing much better. Try adding more nitrogen
