So, ive got some critical yumbolt and sensi star. I started two different batches about a month and a half apart. The older plants have been flowering for about three weeks and are about three feet tall, the bud formation seems very weak. Im wondering if I should have flowered them earlier and if I should start flowering the second batch earlier than the first. anyone grown this before?
no such thing as "flowering earlier" you set them into flower yourself when you set the light to 12/12, if the bud formations seem week maybe the plants are stretched or not getting enough lights/nutes. I'd give it more time before judging the sites though especially since your only at 3 weeks. glwg
