One of my plants (picture included in week 2) seems to have something wrong with it as shown by the white lines/bright discoloration on the leaves and new growths. The leaves themselves also seem to have a thinner shape compared to the other 2 plants. Is this cause for concern?
I wouldnt worry. The first few sets of leaves can be funky. Just watch out for overwatering and overfeeding. If you're on week 2, there's no reason for nutes, wait until the rounded cotyledon leaves start turning yellow before you feed. Good luck!
no just cut those off, what you want is growth going up, by cutting those off they dont touch your soil, also the energy of the plant goes up, those will just take up energy from the buds at the top
