Don't worry so much about the bottom leave's yellowing,there the first to come and the first to go.I would take the bottom few ince of growth of any how because of the buds that you will get down at the bottom is very little.If you have not flushed the plant or plant's yet then i would do so just incase it is a salt/nutrient build up that the plants will exspell during it's life cycle.Do this by useing water at a ph of 6.5 then leave somewhere like a bath so the water can run off do this till the water run's clear.Then you can either leave the plant's for a few days to dry but i normaly follow the flush with a fresh made mix on the same day say 2/3 hour's after the flushing.I have done this many time's and you might get some people say that all that water is no good for the plant's this is rubbish has long has the plants are not sat in too much water they will be fine that is why it is best to let the plants have a good run of down the bath or shower plug hole.good luck any problems get intouch ................tyke.......................................................
i kinda think its a nitrogen def. but i dont know for sure im a new medical patient and new to growing. i just gave them some roots organic buddah grow yesterday and it might fix the problem within a few days. the first two pics are of the shorter one which doesn't have as much yellow spots but has a few leaves that are twisting. any advice??? BTW:idk what my PH is
