yellow uptured leaves...

7 weeks into flowering of what should be a 9-10 week strain. a lot of my leaves are starting to turn yellow curl upwards. the tips of the leaves are basically crispy. ive had yellow leaves before but it was mostly the big fan leaves in the middle/lower part of the plant. now its crept up to the buds on top. the little leaves in the bud itself is turning. im about to water and don't know if its lack of nutes, or if I added too much already. any quick advice before I water would be great. sorry for the bad photos, but its difficult to get to the hps power supply

after searching some more im guessing this is a heat issue. I have had some hot times in that room. if I keep the heat in check for the rest of the time will it pull through?

oh yeah it will recover most definately

also those pictures look sweet

thx brissel, feel better now. been a long ride to lose these plants this late into the grow.

yes, it does appear to be heat related

holy crap dude, those are seriously burnt
how many watts are you using, and how far is the bulb away from the tops?

HOLLA! my first Dr. Jekyll reply! always find your posts entertaining. I have 1000 watt hps. distance from light is about 3 feet. its weird, I have a taller plant right next to it that is in much better shape. but here are more pics. youll notice the whole plant isn't roached. this is my first time growing any plant, never mind mary jane. this plant was at 1 time high times worthy. now roached. it is Blue Dream. all the same plant:

We once had a plant too close, but the tallest/closest buds did not show heat damage first, but eventually they did

3 feet does seem like a good distance but in this case it obviously wasn't enough
Hope you have your temps under control and good ventilation
