Preflowering started and leafs suddenly growing very strange!

[420ing]

Hello good people i have noticed something very very different about my plant when i woke up this morning. I gave it a good watering last night with a little magne cal+ added and when i got up this morning i noticed that all the new leaf growth is suddenly very different to what it was before.

It's as if the leafs have become very very long and thing and they are kinda curling down/twisting around. I think that vertical growth has stopped and beggining its preflower stretch at day 31 now. I have a few pics here so you can see what it is im talking about.



What is going on here?

Im also confused about feeding. I mixed 2 soils together bio bizz allmix at 40% then 60% of plant magic soil supreme. I had very dark green leafs at the start a few of them were curling down/twisting slightly but it grew out of it although there are another couple higher up that have it slightly aswell but i don't know if a low humidity of around 45% during my veging caused this to be more pronounced or worse. I kinda got the impression it was slightly over fertalised with N at the start? I don't know if im meant to start feeeding it bloom nutes with this mix of soil i have chosen or if mollasses is good enough on its own?

To be honest i've not checked the PH of the soil yet but i will do that later today. I do know that my water is around 6.3 Im using a UFO light that draws 87 watts from the socket and i have it on a 20/4 schedule right now i only started to do this a couple of days ago previously it was under the light 24 hours a day with no dark period. The temps are a little lower than they were at the start. It used to be around 27c when i started the grow but now its hovering around the low 20's since around a week ago. The humidity has also risen from an average of 45% to pretty much a constant 70% since last week. The temp drop seems to have coincided with the rise in humidty and wondering if the 2 are connected? I've not been feeding her at all except for standard amounts of plant magic magne cal+ with almost every watering. The 2 time's that i didn't feed her with this she seemed to develop yellow streaks on the leafs and those tiny little orange spots. The soil is a mixture of 40% biobizz allmix and 40% plant magic soil supreme and its in a 20 litre airpot.

The funny curled new growth is normal where the buds are starting to form.Keep feeding veg nutes and cal/magat1/2 strength until you see her vertical slow.

I have the same issue with my royal ak under led light, and was advised to add some cal mag to the veg nutes, just as namvet25 said.
I will post an update with plant progress so feel free to
