Hey guys n gals. I’m getting a slight issue of discolouration starting at lower parts of plants. 3 strains. Gold l, purple h, banana all photos.
pH religiously checked every feed in range of 6-6.3. all in perlite
First week on grow. Using advanced nutrients at 1ml P/l half strength and their root product tarantula at 2ml pl .lowered the dose of a and b trying to diagnose it 3 days ago. It’s got worse as of last night. Just upped them to full strength just then to test that out.
Please if you have any ideas I will be very grateful.
