Hi All,

I planted just a few plants in rockwool, until my system is done. It's been about 2 weeks and I started to see a few things. 

1. browning of the leaves, with tomatoes and okra

2. Some squiggly white stuff on my leaf lettuce. 


Can anyone identify these and help with with solutions?


Thanks in advance!!!

The squiggly lines on leaves is usually leaf miner and it generally doesn't hurt the plant enough to be a problem so I wouldn't worry about it.


The browning of the edges could be from a few different things.

Have you added any seaweed extract?  Potassium deficiency can sometimes cause issues.

What is your pH?
