sounds like the exact same thing happening to me. ive tried flushing and adding cal mag. im starting to think ive just been over doing it with the nutes. i try to stick to the fox farm schedule, but when i pour the nutes into the little measuringspoon, i might be guilty of filling it to the top and maybe a few drips over. Next grow i think i will take it way ez on the nutes.
someone mentioned in another post of mine " too much nutes, AND under watered" maybethats the case. i thought i did a good job of watering but ill try to do it a little more often.

I believe you have a case of severe heat stress. doesn't look like nute burn but it does look like salt lock up. how hot is it in your grow room? Heat looks like your #1 problem here

hi grizzdude, thnx for the reply! im using a 150 watt hps floralux, and i keep the plants about 1 inch from the glass cover ,and i have a little ocillating fan right on it. i figured as long as i keep the fan close it would be fine cause 150 watt doesnt put out too much heat. grow room stays just at 79 degrees most of the time. i guess it wouldnt hurt to raise the light a bit lol. thnx again!

A good rule of thumb is to put your hand under the light and when you can keep it there and it feels comfortable, thats the distance you want from your lights to your plants. Good luck dude!
