my plant is in the beginning stage of flowering and has a few problems. The first problem is that some of the middle leaves tips are curling down and the sides are folding under themselves. the 2nd is that some of those leaves are also droopy and also have like a spot that is kind of a rust color that is growing. the next problem is that a pair of 3 leaf fan leaves on the very bottom died and dried up and now the second pair of 3 leaf fan leaves are half way dead and dried up and i think its goin to do this the whole way up. and the last problem is that my main stalk is strong at the bottom and weak at the top by the flowering sites.
