Good news! I've added an oscillating fan, so no more box fan beating up my plants.
I mounted it to the floor to save some floor space. Fuck the massive stand it came with. If I used it, the fan would be in the middle of the box.
As far as the girls are concerned, they're looking nice, and growing by the day. The Magnesium deficiency has begun to dissipate and they seem to be eating the Co2. Today is day 28, and hopefully I'll be flowering soon. Any opinions, how tall should I let them get before they flower 20 inches? 2 feet?
I think a lot of depends on the medium you grow out of. I use Fox Farm's Ocean Forest, which is full of nutrients. Most people say you won't need to feed for the first month, but I started after 2.5 weeks, when I started to notice discoloration. From what I've read and been told, never go above 1/4 strength of the recommended dose. I'm sure it's safe if done properly, but being a stoner, I've noticed it is easy to fuck things up.
Here is a brief summary of the feeding table I use, from
The Cannabis Grow Bible, which I recommend to any novice, such as myself:
-For seedlings, use a soil with an even NPK and no nutes.
-After germination, don't feed for three weeks, unless the plant shows yellowing, if you do feed, use an even NPK, or one with more Nitrogen 20-10-10. Use at a 1/4 strength.
-If your plant shows any yellowing, increase feeding strengths until yellowing stops. Increase by 25%-33% before trying 50% or higher.
-In the second week of growth you should be adding secondary nutrients. Mix at a 1/4 strength. Give your plants secondary nutrients once, every other week (This is where I fucked up and developed my Magnesium deficiency.
-Once every second week, add micro nutrients at 1/4 strength (This is why I like Age Old products, they have all the micro nutes you need, in the grow and bloom blends).
-When Calyxes arrive switch to a food with a higher P than N and K (1-2-1) and continue to feed as usual.
