First Try Lemon Pie Auto

Your plant is only beginning to set it's first pair of true leaves. I think you are seeing normal growth. I personally don't use humidity domes much. My natural humidity is above 40% anyhow and a dome can cause other issues if you are not careful. When I do use a dome I put it on when I plant the seed to cut down on watering need and I remove it when the plant is about your size. I don't want the plant to become reliant on "perfect" and I want it to toughen a bit to handle normal growing condition fluctuations. I am a bit concerned that I don't see the top of your pot in the photos. It doesn't make sense to buy a 10 gallon pot and only put 7 gallons of soil in it. If done properly the more soil means a large plant able to produce more yield. By not filling your pot you are essentially using a smaller pot size. And, the soil level will drop during the grow leaving even more unused pot at the top.

Not really, this is quite normal for young seedlings while they still getting themselves organised and embracing life. They certainly do not need a humidity dome or other pampering, cannabis is a tough and resilient plant which also needs good air exchange to function properly, something a dome will prevent. I am sure in 10 days you will be wondering what you were worried about! Cheers, Organoman.

Definitely a fem. As for any signs of male traits - or “herming” - no I do not see any. Looks just like some big calyxes/bracts

Hey pal. This is a case of marco/micro nute balance been off. As I can see in your profile pics the problem leafs seem to be the sugar leafs/leafs coming directly from bud sites? And your fan leafs are of an okay color yes? Okay, so here is the simplest version I can explain and then you'll need to look it up to understand more, don't worry ill also give u the fix. If you want more detail DM me. Okay, so here goes. Autos have things like ruderails its what gives them the ability to grow within a 9-11 wk period and they control their own flip. With ruderails the more an auto has, and some info on autos has the amount of % of RR. Anyways these RR need micro nutes, (immobile nutes), as apposed to marco nutes stuff like NPK and 1 or 2 others that get draw from your bud sites and brough to new growth such as flowering bud sites. With micro nutes you'll see these leafs showing defs around the very sugar leafs, or top leafs as you call them the leafs around the bud sites yes? I haven't had a look at your nutes and what you are using but I'll look what thru has the best/most micro nutes to help with your problem. Now, them leafs won't get better, they'll stay like that but nor will they get worse and more importantly it'll but your bud sites back to growing cause atm they aren't doing much when focusing on drawing nutes/energy from your bud site to help the leafs. Its all very complicated. Really interesting stuff and when you get an understanding of it and how giving flower/PK boosts at the right time will transform your grows. Really key stuff to learn. Micro=immobile/marco mobile nutes also look up fungi/root stims. Helps nute uptake. Will pop onto ur diary now.
