Help with my 1st plante ( Newbie )

Newbie here start growing maybe 3 months ago with 4 plants now it's one out of 5 that survive and I notice it was taking a long time to grown for not getting enough sun for keeping it indoors with CLF lights but lack of humanity and no real air flow into 3 weeks ago we started getting some good sun so I keep it outdoors and it start growing but now here's the problem...The new grown are starting to show claws and maybe a few brown spots ( not many)

I have the plant in FOXFARM soil
I Feed it sugar Peak 3-1-5 every other water. I've been feeding since it turn 1 month.The PH is around 6.0- 6.2

Now I read it might be calcium deficiency and it do show signs so I just need somebody advise.

Please help me solve this problem

Looks healthy to me, wouldn't worry about it at this stage.

^^^^ looks pretty good and green.

Ok thanks!
