    SOIL Ph fine, soil good, nutes good, but yellowing leaves

    Is this normal? The larger and smaller lower leaves keep on yellowing. I know this usually means the ph is off, the nitrogen is off, and/or the mag is off, but: Ph is 6.5 (I measured the runoff from the soil), I am using BioThrive, CalMag, etc from General Organics, and I am not over or underwatering. The light is a viparspectra 300W and the light is about 1 1/2' from the plant. It's inside in a tent. Advice?

    I'm not saying this could be the problem but I'm pretty sure that's a little too close to the plant for this light..specs read 18" for flower and 22/24" for vegging plants.

          And lower ur ph to more like 6 the soil run off is always a bit higher so o go a bit lower to keep the root zone happy
