I have a few plants budding in soil envy thing seems to be fine except a few of the buds are thin on top and not swelling much, but a few inches down on the plant is nice fat and amazing? Other plants next to it have great tops and some other branches on the same plant have great fat tops? Any input or advice? I'm under two 600 watt hps and 1 1000 watt mh. Soil, 3 weeks in bloom temp ranges from 75-85 humidity ranges 20-30. Thank you for any input!
