Yellow tips, Red-ish stem, Yellow Spot

Hi guys,

could use some help.

These are two weeks old. Grown in top shit soil. Watering occurs every 2-3 days. 6 CFL bulbs equal around 10000 lumens. The light is about 5 inches from the top of each plant. Plants are Super Lemon Haze and Strawberry Haze. There are 4 plants (2 SLH and 2 SH), all treated equally but only these two showing the yellowing tips on the first lower leaves and barely 2 yellow spots altogether. And there is some red showing up on the stems as you can see on the last picture.

Obviously no fertilizing has been done and they live in a closet with enough space. Havent put ventilation there yet so that might be a problem. The temp is regulated at all times. Water clean as a whistle...etc.

Anyway, please check the pics and tell me if I have a problem or not. Will this progress to upper leaves as well? And is the redness something to worry about?

Thnx for the effort.

Cheeers!

Looks awesome! Its overwatered (may be the cause of that discoloration). You can tell because the cerated edge of the leaves are stretching out so it can dissipate extra water

It could be overwatering in a somewhat dry atmosphere. I've read its better for the plants to be in a dry atmosphere rather in a moist one. I guess this is a bit too dry.

However, I believe its most probably lack of Magnesium which occurred because I watered them with tap water maybe once or twice.

I'll make the atmosphere a bit moist and add MgSo4 and see how it goes from there.
