What am I doing wrong? (pics)

I have a grow room under my basement stairs, 3x3x7 plus the rest of under the stairs. I have a 1000w HPS and 4" inline fan for ventilation blowing through the eclosed hood and to the outside.

The temperature was so hot in my room ( around a 100 degrees) so I had to hook up the vent fan to the light and Jerry rig a window air conditioner with vent tube to cool the room. ( after much trial and error with fans and such) It is now just below 85 and the plants have not improved much.

I have 4 bagseed plants and 4 clones. Bagseed a month and 1 week old and clones Ive had for about 3 weeks. All are stunted with brown dying curled up leaves.

I grow in soil, two differant kinds for bagseed and clones, never used any fertilizers and plants are about a month old and bageesd has never been transplanted, clones once.

Any Ideas?

I thought the drop in temperature would help them but now I think It might be something else.

Also, the air from the airconditioner is venting right onto the plants ( my only choice to control the temp.)

will that damage my plants?

its not the temps, plants can tolerate up to 95*F. most sativas can tolerate temps in the low hundreds (outdoors of course.)

U need to flush immediately. and transplant them out of that scum and into some real pots, with either healthy loam soil or peat moss, and lots of perlite.

after U have done that wait for the plants to get better, then get some all purpose veg nutes and superthrive from walmart and mix 1/4 strength nutes and one cap full of superthrive in pH'd water. feed them that nute mixture once per week, and water them just enough to keep the soil moist between feedings.

i dont think u need to add anything right now, it appears that the pH is decent since the plants are still perky, and they dont have the ph fluctuation spots.

when the bottom leaves are the first to start yellowing, that should be a red flag letting u know u either have a deficiency or the plants are root bound, or over watered.




a few of them actually look pretty good. keep it up

For starters...move your ballast to another room. Lots of heat comes off that. I also read the bends, droops in the dryer hose impedes airflow. I have been getting way too high of temps also. I have been working on getting my hoses more in a straight line and will be working on it more tonight. After I see if any of it helped

Wow what are those plants in?

Dirt from a 20 year old flower bed? Man atleast get some miracle grow soil lol.

You need to check your Ph and nutrients in your soil and like above read your ph on your tap water.

mine is ranged between 6 and 7 but closer to 6.5

Feed em man. They look like theyre starving..

Add some compost, it's real cheap.

I can almost hear your plants screaming, "feed me!".

Your plants will clear right up once they get some nutrients.

omg pls take those out of the cups...NOW

ya id say ph has dropped out so no getting foods and way to smnall a fan for a 1k bulb. plants can not take 95 with out co2. and not for very long either. thwe soil does look poor quality and dont go buy wally world nutes. nothing they have is any good nro any big chain stores. if you are suggested to get superthrive thats at a hydro shop..keep buyin foods there. youll end up with mg at wally world most cases and is no good

if you look at cfm ratings of fans, a 4 inch is about a third as useful as a 6 inch. I would consider a good 6" (450 cfm) minimum for that set up, and use the 4" and room ventilation. It will be worth it for sure, it will get rid of a lot of that heat.
If it was my problem, i would but those little plants under a flourensent in your house somewhere and get the tent environment figured out by turning it on with my new 6" fan and a thermometer that records the high and low and then put the plants back in when the environment is good.
