I currently run a bloombox set up and have 6 plants flowering. I use advance nutrients and change the water every Sunday. I use the feeding schedule that came with the box and have the c02. The last week I have noticed the tips of the plants curling and/or turning brown and crispy. Does anyone have any idea what could be causing this?

Could be heat or potassium, my guess anyways. How are the temps?

nutrient burn..flush out your tank and mix up a new batch of nutrients about 1/2 as strong as you have been and see how that works out for you...

The temp is ranging at 76-80.
I'll do a flush. Thanks, everyone!
