I know that it is best to stop using ferts 2 weeks or so before harvest, but as a first timer, how do you know what they look like at this stage? The plants in question are skunk/s.India and they went into flower under 24 hr. light 4 weeks ago (400w hps). They have been on 12/12 since then and seem to be flowering well, the top buds are about 8 inches long/ 1 1/2 diameter, and many smaller buds lower down.The plants themselves are only 22 inches high(bonsai ! ) and because of the unusual way they started flowering, i dont trust the flowering time given on the packaging (9-12 wks). Quite a lot of the leaves are yellowing now ( Nitro migration ? ) Sorry to be so long-winded but i wanted to be sure you had all the info. Any ideas anyone ?
