Hey guys. I can't figure out for the life of me why my month old plants are browning at the tips at the bottom of the plant!!?! I think I am doing everything right, which is probably my problem, but does anybody have any idea what it could be??
Here is my setup and what has been going on:
-I am growing 6 plants in a well ventilated closet
-I am using an ebb and flow system
-They get watered once a day in the morning, the rock wool soaks it up pretty good and stay moist all day
-They have been vegging for about 3 weeks
-They are between 7 and 9 inches tall, about 7 to 10 inches wide
-I started using nutes 1 week into veg. I started with full strength for the first 2 weeks and I flushed the system this week with first 6pH water then 6pH water w/ 1/2 strength nutes.
-I have been watering them with that for the past 4 days.
-I have a 600W MH light about 2.5' above the plants. It seems a comfortable temperature under the lights, and the thermostat reads 78-82 degrees through the day
-Light cycle has been 18/6 since day one.
-2 fans in the closet blowing around plants all day, closet open to rest of room all day w/ large fan, overhead fan, and open window. I feel as if I have ventilation covered.
There is also this green mold that is growing on the rockwool. What exactly is that? and is it harmful to the plants?
I realize that I may have duped up with the nutes at the beginning. What affect could that have on them now?
Those pics are a few days old and the browning and mold have both been getting worse.
Hmmmm what could it be?
