m0useanswered grow question 3 years ago I don't think it looks drowned but it does look like it is starving. Zero feed and cant grow with out it.
What are you feeding the plant?? nothing is listed in your diary.
My guess is it needs food. not all soils are equal and same goes for coir.
Don't forget you need to add in CalMg with any coir based medium if its 30% and up if you feed does not have ample amounts.
Good Luck!
