I've been growing this plant of unknown strain (seedbag) and put my 400w HPS light on 12/12 4 weeks ago today. I don't know if flowering starts as soon as you switch or what but its been 4 weeks since the switch. I think the buds look pretty small compared to other peoples pictures. Anybody think they are looking good? My leaves do have lots of nute burn and I flushed the plant a day ago. Hopefully this works but it doesn't look much different. http://imgur.com/fu2ytjT http://imgur.com/MrjUPvH http://imgur.com/oOkWRHs http://imgur.com/cAtwrjk
They look okay. You still have 4 to 5 weeks to go and they will fill out a lot during the last week or two. After switching to 12/12 it take about a week for the plant to begin flowering. your doing good, just lighten up on nutes and make sure their getting nutes that are relatively low in Nitrogen.
I usually feed nutes once a week and regular PH'd water once a week. During flowering I feed Fox Farm Big Bloom and Tiger Bloom. Flush every second week and when your a week or so out, just plain water until harvest. Good luck!
think that's the norm for sativas this is my sativa at 1st day of week 4 View attachment 142684 was convinced she stunted coz indica not far from crop, so yea looks good to me
Indicas can flower up to, if not more than 5 weeks faster than Sativas. They also mature much faster. Sent Via My Pokedex http://forum.grasscity.com/index.php?/topic/1305920-Kushgodrex%27s-First-Grow
for comparison this is my indica at week 4 and now (week 8) View attachment 141744 View attachment 142685 think she got another 2 weeks, buds on filling out mode atm so yea id still say you on track for 4 weeks
