How much fresh air are they getting ?

Sorry but just a temp difference won't do that or how do they get buds to grow in Hawaii ? Temps are always 90 or so.

Sounds more like PH lock out or to me it sounds like 6 weeks is when they seems alittle slow but pick back up and put on the weight. If they don't get enough fresh air meaning CO2 thing slow down to a stop. 40 plants and 10- 1000 watt light really burn up the co2 in a room.

I am running 40 buckets with 10 1,000 watt sodiums. 12 on 12 off. the first 4 weeks were great, I was getting good growth but did have a few issues in between. I went on a 3 days trip and a friend that I thought was watching my home let my temp fluctuate a whopping 50 degrees. Day temp was 50 degrees and night he let it get to 100 degrees. So I got the dreaded PM. I have burned sulphur twice and it seems to be controlled Rating: 5
