[stamate]

Hi guys i have 5 nirvana northern lights , until 4 week of flowering all was good but now ,on 7 week flowering my plants didn't make very nice buds, i dont know what did get wrong (I think the only thing wrong is tiohat I've been away from home six days and I have not watered at all, from what we usually water each 4 day) .
They are under 600w hps , using biobizz nutrients and the water always have 6.5 ph, temperatures maximum 25 celsius .

what do you think? are they looking bad?
this pictures are from 4 weeks flowering :

rest are from 7 weeks flowering :

Could be locked up. Flowering P def is possible.

If he has it at 6.5 it can't be locked up...do you have enough air circulation?

air circulation yes but on that 6 day vacantion they were closed in that room without fresh air... usually i open the room windows every 1-2 day for fresh air, this it was the problem? just upper leaves are damaged , leaves from the down side are very healthy

Well your saying you haven't watered for 6 days which probably isn't great and no fresh air. You've probably answered your own questions dude

They'll recover and pack on some weight with air and water. They look fine overall, and should bounce back within a week or so. Just don't cut early.

Dear, how I love you Picture!

Anyways; to the op, do you have a fan blowing on them? What I would personally do is water them, have a fan blow on them, and feed them some co2, grab a nice short glass fill with a few cubes of ice and pour some nice 10-12 year old bourbon over it, sit back and enjoy.
Give it two days or so and check on them. Just try not to stress to much because that might lead you to do something you shouldn't. But that is just my opinion. :l

PHed water and air circulation should bring her back in no time
