hello
a friend has a few plants that are starting to go bad 4 weeks into budding..some of his plants leaves started shrinking and going away at the top of these plants..where their was once bushy leaves at the tip of his plants is now replaced with a leaf here and there..and its not a whole leaf..you know how a leaf has 5 points well his only have one tip..and the budding has slowed to pretty much much nothing on the top..he was told his lights are to close and thats the problem..even though the top of his plant didnt have burn spots the leave were just twisting and shrinking away and the leaves are not dry..so he raised his lights and is hoping they will do better..
my question is: will his plants start to grow good leaves again? ones that dont twist and shrink away?..will it bud better if it was that lighting problem? or does it look like it could be some other problem besides the lights..ph is fine
he also is growing in 3 gallon pots in granulated rockwool..the rockwool has settled down to a little over half the pot..can he lift the plant out of the pot and fill it with some perlite and place the rockwool on that? (since he cant get more rockwool)..plants are 35 days old.
