 white russian ebb and flow problems. root rot? | |
ok i am attempting to grow some white russian using and ebb and flow system with rockwool cubes in hydrotron clay pebbles. i am using 2 400w lamps my temps are around 80. about a week ago the plants were accidentally flooded for 15 hours and i think this is my prob but am not sure. Ive posted some pics please ask if u need any more info to give an opinion.
a few things i suspect are
1. the salt on top of the cubes. is this a prob?
2. are (can) the cubes (be) too deep in the pebbled?
3. there is a slight amount of water left over in my trays will this small amount cause root rot?
4.my Ph and EC are going up even though the EC is a .3 in the flowering room.
it looks like a nut prob to me but why is the EC going up?
the roots are a slight tan color is this bad?
i noticed this prob in the older fan leaves first
