ie told him to feed from the top i dont know why he does it. i havent got a clue what that green stuff is i thought the same. all i know he grows in coco soil uses a + b which we think he gave too much of and he gave a feed of bio - stimulant, flushed out for over 2 week now and has gave 1 little feed. but the tops leafs look good then go they same way as the other leafs. the process starts at the tips then gradually takes the whole leaf curling up then dying. he has this halo foiler spray what has magnesium supplement in it but hasnt used. its his 1st time using coco products too, which was a bad mistake, when i start ill make sure to have a good read up on this forum 1st.

and plus theres hardly any roots coming out of the bottom of the pot.
