Hi all, long story short, 5weeks in flower and leaves are all yellow, I have tried dosing up on N but to no avail. Started about 2 weeks ago The new growth appears ok but the fan leaves are getting worse. I grow in soil using 250 hps and biobizz nutes. Any ideas? Ps, strain is Maui waui (sativa with about 11 week flowering time)
Time for an urgent flush, to reset the rootzone, to my blog the flush http://forum.grasscity.com/blog/1093/entry-9829-fl... On closer looks avoid them clay pots, unless you sealed the inner pot, the clay may well have sucked up much moisture leaving your ph in wack ..avoid this by going plastic ..good luck
Thanks for the reply, you think a flush is needed then? Also the pot is plastic, just looks like clay
Its normal for leaves to yellow during flower. They use the nutrients from the fan leaves to produce more buds from what i know. If they are flowering/budding properly i would just grow them as normal and maybe flush a week or 2 before harvest. Based on what i see in your picture.
