My temps are 72 to78 ,I have a exhaust air and a good fan on all the time RH is about 60%How is the condition of the room temps,humid? Are you exhausting your air? It looks droopy like it hasent been feed enough Im a hydro man so IDK the feeding part but 6 days ago seem like a long time with out food when my plants droop its because its to much water or to less water you have to figure that part out. I would def flush tho just in case, flush in hydro helps all the time Im pretty sure dirt will too. let us know whats up.
Yes ph water 6.3 is good too. the temps and humid is good. You got the exhaust fan. I say flush.Flush it with just PH water 6.3???
