Kleine gelbe Flecken an 2 Blättern I saw today that 2 leaves have developed slight yellow spots. I checked the underside of the leaves and didn't see any webs or anything, the rest of the plant looks very healthy. The question now is whether this is normal or if I should be worried about spider mites.

Deficiency?My current grow is on its 5th week of flower and many lower leaves on each plant have begun to yellow then develop brown spots. I’ve did a little bit of research and I think it could be a nitrogen deficiency. Any help is appreciated.

Yellow tips near bud sites Yellow tips are developing on some of the leaves near bud sites. Is this a cause for concern or a sign of a deficiency? The light is as high up as i can get it and it is on max currently. Also the only nutrients I have added the whole cycle has been small amounts of a compost tea
