The plant has some deformation in any of its leave...

She looks nice and healthy. I don't see any yellow or brown leaf tips yet. If you feel she's getting too much nitrogen just give her plain water between nutes. She will take off with her growth over the next week or 2 anyways. Just keep in mind your doing good reading what the plant needs with auto flower less is best when it comes to nutrients. Lastly develop a good wet then dry type watering cycle if you allow your plants to dry out "too much" before they use all the nutrients as it drys the ppm that's left in the soil increases- hence use plain water between nute feedings.👍

You will never have a nutrient excess using Bio roots and mammoth P as they doesn't contain enough nutrients but more beneficial. You can make a foliar spray , it is good for the plant into vegetative stage. Nos about the deformations it is genetic and it happens time to time so don't worry because your plant will flower in a normal way

Deformities can just happen sometimes. I could be genetics or a one-off thing. Doesn't mean the plant is a dud. I had a seedling that lagged behind my other plants about a weeks worth of growth and looked so odd it didn't look like weed. By the end of the grow it was the largest plant by a good margin. Dark green leaves coule be genetics or too much nitrogen. I would personally say to back off on the nutes you are using but it seems as though you aren't really using anything with much for NPK in them. With that being the case it could just be that your soil is a little nitrogen hot. If the soil does actually have a bit too much nitrogen, theres not much you can do besides just waiting for the plant to use it up. I don't see any clawing, so if it is a nitrogen excess it is not too bad and really shouldn't affect anything as it is now. It has good growth and looks pretty normal for week 3 of veg in soil.

Deformation of leaves happens sometimes, you only have to worry when the leaf doesn't look healthy. You don't have to worry about the dark leaf, the leaf does look very healthy, perhaps a bit too heavy fed perhaps, but... As Dilligaf said, the leaf does not show signs of nutrient burn. I would only water for a couple of weeks, or lower the level of nutrients. Often when you follow the grow/feed chart provided by the nutrient manufacturer you end up with such leaf. (without the deformation) I had some odd leaves too, i ended up yielding up some dank black weed, check my grow

@AtticGrowing The deformity is genetics as my lsd plant has the same issues Even those leaves are a very dark green there are No signs of nutrient burn on any of the leaves so I would say no to the over fertilising . However if you keep a less is best approach to feeding you should be alright
