Thanks for the ideas with my burned buds, I have tied them away from the light. and things look better.

Here's new one.

I'm almost 4 weeks into flowering, I've been trying to keep the Total Dissolved Solids at about 1800 ppm.

This morning I checked and the PPM was suddenly over 2000 (my meter maxes at 2000).

I had figured PPM would diminish over time as the plant absorbed nutrients.

Any idea what it could be?

I changed the water and washed the parts with H2O2, 2 weeks ago, so I don't think it's algae.

Thanks again.
