Help dry leaves in flowering

2 of my plants started to have limp cola leaves in the middle of flowering
then they dried
the hairs are turning red but the buds dont look fully matured
it really looks like the plant is dyeing
i ajusted the ph to around 6.4 but no progress
please check out his link for more details

How long has it been flowering.. can you post some new pics in this thread.. ? please

its been flowering since about january 10th or something like that
no 4th


this one, the first plant used to look like this last week

now it looks like this

the other one started out like this

and now looks like this

the buds have some red hairs on the second plant

but not the first plant

drying out even more now
whats up is it dead?
no cuz the lower buds are still green and so is the lower half of the main cola

looks like what happened to mine ... im interested in the answer too.
is it really hot in the room your growing in?

I think you are having a PH (salt lock up issue)


are you pH ing your water?
cheers

i recently began adjusting the ph although the floranova nutrients says it has buffers in it already

yep
i am sure it was the ph
thanks
got new growth
but should i flush that one?
most buds hairs are red although some buds are not ripe yet
especially the new ones on the top
