Something wrong.

Hi, new to this and need help. Had no problem for first couple of grows, but now I can’t grow shit.



CropKing WW auto flower
Using a GH water farm.
Grow tent.
2 x 400w LED grow lights on 24/7
18 - 24 inches above
PH around 5.7
Straight tap water to start left for 24 hours to clear chlorine 16ppm
26-29 degrees C in the tent
Has an exhaust fan and filter.

Help! What’s wrong with it? The last couple did this as well.

Thx in advance.

Are you reusing the clay pebbles each grow?

Yes, but I clean them in bleach and peroxide for a couple of days. Then after I rinse a few times they soak in ph adjusted water for a couple of days. Then I run the water farm for a day. Then dump and go.

Are you putting nutrients in the water?

I wasn't for the first few days. Just put 100 ppm of Nova Flora Bloom in yesterday. Will start increasing slowly if it takes it ok.

I've never grown with led's but 800 watts sounds excessive for such a small plant. If that's aluminum foil on top it's possibly absorbing heat cooking your plant.

I guess 800 might be a lot. I always assume more light is better. I did raise the lights up more. I will shut one off and see what happens.

The foil is there to prevent algae on the clay. It wasn’t a factor on my (few) successful grows.

Thx for the input.
