Please help identify my Problem: Yellowing leaves with veins showing and some necrosis spots in third week of flower
The odd thing is that only some leaves in the middle of the plant are affected. My thoughts were Nitrogen or Manganese deficiency or maybe light burn (why in the mid of the plant tho?)? I feed Biobizz Bloom, Grow and TopMax, no Problems until now.

The most common yellow leave will be found on the terminal stage of flower because plant will power up for flower produce rather leave grown. Leaves are most of the time a reservoir of H2O nutrients and minerals. Yellow leaves can apear on you plant at some point of grow?

Yellowing on lower leaves. Any idea what this is?
Don't think they should be deficient in anything yet, they're in new Ocean Forest soil and only on day 11 of veg, no way they used up what's in the soil yet. More details in my grow diary comment.

Yellow leaves since 1 week
Hello my friends, More and more yellow leaves since 1 week. I need to be worry? I think it's not a problem of ph because my other plant look healthy. Maybe too much water? I just give her 2 x 0.6 liter per week and fertilizer only 1 times per week.
