This is my second White Widow grow. The first I used an HPS light set at 200 watts for veg and 400 watts for flower with 4 plants and the plants grew normally. This time I’m using a T8 with 4 4’ 32 watt bulbs, 6500k, 2750 L each bulb 3" above the plants. The plants seem healthy but are short and stocky. They are 5 weeks old since sprouting, 3 weeks in a solo cup and 2 weeks in 5 gallon smart pots. Lights are on 18/6 and temps from 62 to 75. There are 4 plants total and the tallest one is only 4" tall and there’s 4 sets of branches about 1/4" between nodes. Should I raise the lights or go back to the HPS or just let them grow?
