New grower, yellow tipped leaves.

Hi guys,

This is my first grow and since yesterday the tips of my leaves are turning yellow.
I'm growing indoor under a 100w led lamp and an extra 30w lamp for extra red and blue light.
I'm using coco coir from Canna as medium and feeding the biobizz line of nutrients together with their Acti-vera enzyme product to make it suitable for coco growth.
I've been keeping the ph of my water around 6 and i stuck to the biobizz feeding chart for coco and light-mix. So the first week i only added 2ml of Acti-vera and the last couple of waterings i've also added 2ml of Biogrow per liter of water. I water once every 1,5 to 2 days and have about a 10% runoff
It's now been 13 days after the seed germinated and came up, since about a day the tips of the leaves are turning yellow and the colour seems to be spreading.
Can somebody give me some advice on what seems to be the problem?
I think i have it narrowed down to a couple of things but im a bit anxious about trying the wrong thing and messing it up.

Anyway i'm happy about joining your community and hope to hear from you guys!
