And its jut starting to get little rust spots but iv moved light higher an iv moved 4 plants into my shed iv flushed them gave them some sulfate of potash an epsom salt magnesium
Light is as high as it can go it's a grow tent bout 6ft high I think an lights right at top it was about 70cm away from plants an light is on 400w super lumens
Its happening to 5 of my plants and iv got one different strand in there as well but hasent happened to that one
Mostly it's the new groth that's effected an little bit of fan leafs but not much
