Can anyone tell what is causing this problem on my leaves.
Berry bomb autos and nirvana papaya autos, in canna terra, 15 ltr smart pots, master grow nutes, 2x300watt full spectrum led's 12/12, ph was 6.0 but flushed on Sunday and now at 6.5, ppm 850.
They are 8 weeks into the 10 week Shedule and buds don't seem to be filling out very much.
Any help and advice is very welcomeeace
