Careful with overwatering and too intense light. The root shaft abords water and the roots hairs absorb the nutrients. Overwatering kills the roots hairs and leads to multiple random deficiencies. Too intense light will cause a photoinhibition and magnesium chlorosis. Take it easy on the nutrients, 3ml/L of a 4-2-4 sounds a lot for a 3 weeks plant, and I’m wondering how many ppm’s in total it could represent. Jah bless

Growing same seed from same company - 1 week behind you - my end of week one looks identical to yours.

Well done, nice structure, perfect light intensity, accurate feedings, this is what your plants are showing in the pictures. The choice of choosing a cultivar from a well established seeds bank like Barney’s is brilliant.
