Yellowing tips appeared in the last 12 hours. I've been using a weak solution of root booster but I'm not sure if the discoloration is from nute burn or deficiency. Once roots are established I'm planning on putting her in a DWC
Have you been ph ing the water going into peat pellet. Likely showing ph signs. I just start them in rock wool in dwc basket. Also gives me a chance to get solution levels stable prior to roots making contact and no stress on plant moving it.
