HEAT!

[roadhd]

Could it be as simpel as out growing the growing room. Top of growing room ranges from 4~5 feet. Plants are now very close to 400w MH lights (inches). The room also averages 80F when lights are on. Is this just heat related or something else. The only option I have is to continue to top if so.

Yes that looks like heat damage.

[stinkyattic]

That damage is mostly heat/light damage but I think you may have a little somethingelse going on there... Okay, I see a few things- the curling leaves, the random round necrotic dots, the burned tips, and then the regular striping on a few of the older leaves.
Flush out your plants really well and feed them with a complete fert that has micronutrients- if you have any way to check pH, make sure it is in range. It looks like you have a salt problem resulting in a lockout, that's what I get from the burned tips and stripes.
All the other shit yeah get your temps down but really you need some serious ventilation as well, and raise your lights! Also, stop watering with the lights on or be more careful not to splash water on the leaves. The polka dots are burns from water droplets sitting on the leaves under the HID.

What are you doing for ventilation atm? That is contributing big time I think.

oh my god stinky attic you pay better attention to that picture then my gp(doctor) does to me :thumbsup:

[roadhd]

Thanks for detailed replyâ?¦. I will include pic of grow room and you will see my challenges. I have an 8000 BTU portable AC unit in back of room. I vent exhaust into attic. The room is only 4â??x8â?? with a 4~5â?? ceiling. Under a staircaseâ?¦ Half of room 10 Plants are in Turbogarden Ebb and Flow which place plants much higher (closer to lights). Other plants are in 5Gal buckets. The lights are as high as I can get them. I have even moved the lamp over the Turbogarden to 45 degree to mke additonal room. Any other advice or oberservations would be much appreciated. My first indoor project and have already made many mistakes but have injoyed most of learning curve.

In addition plants in buckets have been on 12/12 light for 50 days and still no flowers.

No flowers after 50 days, and those plants are certainly old enough to produce, you have a major stress problem going on, possibly a light leak in addition to the heat. And are you still giving them a lot of nitrogen?

Anyway check for light leaks.

Hi roadhd,

Nice room.
Try to get your vent tubes as straight as possible, any bends can dramatically hinder your airflow.

As usual, stinky has all the answers, with some wit at no charge. :thumbsup:

stinky and kp were the reason my first grow was so bountiful.

Light leaks were my big problem, lost 3 weeks.

keep the faith. :thumbsup:

Well, you shouldn't go into your grow room with your weiner on fire next time, durrrrr!!!

You said room averages 80degrees lights on, maybe so, but for your plants to burn up like that it must be at least 90, at the very very least.
