I have been growing my plants in hydros for a couple of weeks. I am using dw culture. They have heaps of bubbles and I fed them half nutrients last week and topped it up another half a few days ago.

As you can see one of my plants is curling up and the other is beginning to get yellow in the edges of the leaves if somebody can help me fix this bullshit? Also my ph is between high 5 and 6.

Thanks :)
