New indoor grower here, I’m thinking i have about 2 weeks before harvest, pictures are of my DWC is it normal for the leaves to start consuming themselves as seen in the pictures?
It is normal to lose older leaves as the plant matures. I would say more like 3 to 4 weeks based on the images supplied. You could start dropping your salt levels in the buckets as the plant is not consuming as much as when it was actively growing.
Thanks i had been using about a 1/2 tsp per gallon and keeping the PPM right at 1,000 and PH at 6.0 to 6.5, mainly TPS Grow, Floral Micro and CalMag.
For future reference I’d add silica and cal mag to your mix.
You could start lowering the TDS to around 750 ppm at this point.
Got your USB Microscope/camera?
In a week it could be delivered.
Seeing is believing.
Good harvest to you.
In dwc your ph should be between 5.5 and 6.3. You shouldn’t need to ever go above 850ppm in DWC. When your ppm rises to the 900 mark you add water or clean the buckets.
