Can anyone can help with what may be causing the lower leaves to yellow, its happened pretty fast, over the last 2-3 days.
Has to be a nutrient based?
the plants went about 5 hours longer than usual without watering a few days ago.
the plants are on day 40.
ive been very reserved with nutrients using only around half the recomended doses.
im using Bio bizz: GROW,BLOOM,TOPMAX
In trying to combat the spread of the yellowing ive so far:
Yesterday i made up a foliar spray of epsom sallts and sprayed the leaves.
Ive upped the nutrient mix by an extra 0.5ml on each.
Any help mucho appreciated.
