Plants dying, fan leaves shrivelling up

Hi, I have 2 818 headband plants which seem like they are dying. They are 2 and half months old, been flowering for 7 weeks. Ph got high ( around 7.2) as my roommate started feeding with tap water, I got it down to about 6.5 currently but luck yet with them looking healthy. Gave it some nutrients a couple waters ago but a very mild dose. 400w hps, temps at 22 degrees Celsius. Any ideas ??

what nutes are you using it could be yellowing from a nitrogen def.

you adjust the ph..good
i think you will be fine. 8-9 week strain. you only got a week or two to go. check your trichomes.

good luck

What Ring said. You're about done. This is normal and actually a good thing ... your bud won't have extra sugars and salts, which are a common cause of harshness or poor burn. cn
