My setup

400 watt MH/HPS light
4'x4'x6' tent
Exhaust fan w/ carbon scrubber
2 osilating fans inside
1 fan blowing fresh air from outside tent
1 humidifier

Soil: mixture of 1/3 happy frog...1/3 ocean forest....and 1/3 perlite.

2 'Afghani' photo period plants in 5gallon buckets

2 Autoflower plants in 3.5 gallon buckets
(1 Critical jack and 1 sour diesel)

Temp: 75-81 degrees
Humidity: 40-50%

Christmas day they will be 1 week old. I'm prepared to give their first dose of nutrients(about 1/8 the dosage it calls for) on that day. Is this a good idea?

Also I have more seeds should I add more plants or how many should I grow with my setup?

Any suggestions or tips would be great. Thanks

Thanks for ur input.

When would you suggest starting nutes?

Also, do u think my setup could handle 6 plants? 400w mh/hps.

Maybe like week 3/4 from seed.

In my experience, ocean forest has a ton of nutes..

Maybe at that point start with half strength?

^Just some input, not necessarily exactly what you should do

The very tips of the leaves on my seedlings are slightly starting to curl up towards the light. They are almost 2 weeks old.

My humidity is staying between 40% and 60%. Temp is between 75-82 degrees.
I've watered them 1 time (dec 27) since planting them in there final buckets on December 23.

My lights are running 24 hours a day.

Any help would be great! Thanks!

I've already got an mh/hps 400 watt setup with 4 plants under it. 2 of them autos.

Now I'm thinking about adding 2 autos every month to enable a steady non stop supply. Eventually I'd be adding 2 and harvesting 2 every month.
I'm thinking ill need to add more lights to pull this off.

Looking at adding 4 cfl daylight bulbs ariund 40 watt each. Then ill be able to movebthose around in order to get light all around plant while the mh light does tbe rest.

Any tips on how to go about this?
