leaf problems

hi,

am new here and seem to run into some problems with the leafs.

one got a brown patch at edge of leaf and the leafs are pointing down

am growing in rockwool water with water with a ph of 5.9

temp is 80 and humidity is 40%

also the leafs seem fragile and the tips are bent

do anyone know whats up with them?

1. Leaves pointed down is a general sign of over-watering. Maybe cut back some.

2. pH of 5.9 seems high to me. I try for 5.6-5.8.

3. Burnt tips is a sign of over-fertilizing. Don't really see that with your plants. They look fine to me. I always have 1 or 2 plants that don't look as good as the rest. Basically, the weakling of the group.
 
thanks for the replys

no nutes i did put a tiny bit in but flushed it few hours later so dont think be over fertilizing

maybe when flushed bit over watered but before that the cube was really light and that when i watered them

the leaf got a brown bit on the edge the tips seem fragile and a tiny bit lighter green then the rest.
