ONE 750 HPS. im using one of those grow tents and i think the hot water heater and the house heater are piosioning my plants. all the leaves on this mother i got went from green to yellow in aout three weeks they are drying up and have some wierd looking spots on them the mother is in a 6x6 rock wool cube. i took clones from it they are still living but leaves are dying and drying up i thing its a ventalation problem. im using fox farm soil i have the clones in plastic cups.

Is it a new hydrohut tent?

to my knowledge, its pretty tought to poison a plant with co2.

however, the heaters may release monoxides or other gases (rediculously dangerous, and even more rediculously unlikely)

check your ph, watering, and feeding habits

damn man...you have the identical thread in the indoor forums and i replyd there.

recap: 1) hard to give plants too much co2
2) therefore its probably a ph, moisture, or nutrients problem. (or temperatures.

3) post pictures

Please limit yourself to one thread per topic, thanks.
You need to give other info besides the location- there's a sticky in the top of the problems section. Fill out the info, take pics if you can, and report back.
It sounds like you are locked out. Rockwool must be watered at a pH of 5.5-6.5 and you must provide ample Calcium.

even with numbers as high as 2000+ppm

Locked out and deficient are not the same.
Yes, ESPECIALLY with numbers as high as 2000+ :eek: ppm.
