2nd grow, Ethos, 2 strains

Alright everybody. It's been about 2 weeks. Let me explain where the girls are at! I germinated on that sunday night/monday morning. Planted on the following Wednesday. Come friday 1 mc seed did not sprout so sunday I re germinated 1 mandarin cookies. (Root had brown tip, prolly from dirty fingers.) Replanted the seed on tuesday and it sprouted nice and strong by thursday. This Wednesday will mark week 2 from planting and week 1 for the 1 seed. I plan to swap after the week behind one looks ready to see how much the extra week of veg from what I'm doing already will effect my yeild. Today I filled the pots to the rim. I wanted to update something. Yesterday I showed you guys the update. And I mentioned I filled them to the rim, well I also moved plants from 3 lights to 5 lights spreading them around. Well when I first set this up i put the magnets south side up under the trays in the begining. Well I did not add magnets to the ones I moved forward. And if you look. Over night they all slightly stretched. Well the theory of magnetic fields on plants is that it creates shorted heavier bushes. I can't say any of it is true or false or whatever, but to me, it looks a little like they let go to me. Idk.
