Issues with plant

Hey! From what you’re describing and especially if you’re seeing purple stems this looks like a nitrogen deficiency. Even though your feeding seems balanced, sometimes plants still don’t get enough nitrogen during veg, especially in soilless or lightly amended mixes. Double-check your base nutrient mix, you might need to slightly increase nitrogen or make sure it’s actually being absorbed (check runoff pH too). The purple stems can also be a sign of stress or immobile nutrient lockout, often tied to early nitrogen issues.

Hey there I’d say over watering and root zone damage is the cause of this let soil get bone dy betw

Did you add the potassium because of this issue or was that before hand? I recomend ceasing everything except the coast of maine soil. Or stopping the soil, swithcing to something inert, then continuing feeding as you described with your amending.
