Just change out the res. Assuming you are using a hydroponic medium, there's no need to do anything else. In veg, you can probably get away with just topping off the res and changing it every 2 weeks.

Coco and Worm Castings - Does Total Dissolved Solids Matter?Does total disolved solids (TDS) matter when growing in coco, worm castings, and organic dry ammendments? Am I at risk of a build up of salts? I have seen 2700 ppm in my current grow, but are these simply not salts and therefore OK? Plants look good happy. TY4y ago

Forgot to alter pHHi I forgot to alter the pH. I already have some issues (I think pH? Check picture). What’s worse, overwatering or too high pH? Do I need to flush ASAP or wait till next watering cycle? The pH of the water I used is 7,7 and I have organic potting soil so is it a big deal or not?Feeding. Deficiences
