I think those yellow spots r nitrogen defincey u cud hit em with sum N nutes, they look tall and strong enough to start blooming, i hit it once with some nitrogen, then force it to flower by giving 12/12 light s chedule and adding alot of P nutes like schultz cactus plus is a good alternative to biobizz products
well is it?just normal soil ?
NOT like bloom boster or moisture control nothing, or some other soil that is high in pre-mixed nutrients
u shud get sum biobizz products(
www.biobizz.nl u can order from may be hard to find in store)
use bio-grow for vegitation
and bio-bloom for flowering
also Top Max + algi product are also very good biobizz products that can help keep ur plant healthy...
fox farm nutrients will work also well
ur plant may be strong enough to just start flowering without any Veg nutes, id use fox farm blooming agent
