This is my second time ever growing under artificial light, so I'm still getting everything dialed in -- but I do have a couple of issues I'm hoping someone can help with.
I am growing in soil in a 32"x32"x63" tent under a 400W HPS (digital ballast). I have a 190 cfm fan for air outtake and a 60 cfm fan and 2 axial fans for intake, plus 3 fans in the tent circulating air (2 static on the floor pointing upward and one oscillating fan blowing across the top of the canopy). Temps range from 75 to 80 F at the top of the tent and a few degrees lower at the bottom.
I have 4 plants now 2 weeks into flower, which are getting cramped in the small space, but seem to be doing pretty well anyhow. Here's a pic of my girls:
They are OG Kush (rear left), Sour Buddah [Sour Diesel x Hindu Kush] (rear right), Berry White [Blueberry x White Widow] (front left), and Jack Herer (front right). My issues seem to be plant specific, and only affect the OG Kush and the Sour Buddah.
The issue with the OG Kush, I believe to be a Cal-Mag (or one of the two) deficiency. The leaves are very light green, and almost look like nitrogen deficiency, but I don't think that's it. take a look:
None of the other plants exhibit this issue. My friend who has grown OG said it's a heavy feeder from what he remembers. When I got the plant as a clone, it was pretty beat up already, and I've been trying to get it back to health the whole time, so it's not too surprising that it has a issue.
The issue with the Sour Buddah is totally different, and seems to have some leaf curl going on. Take a look:
It could be heat, but that plant isn't that much taller than the others. I have the 400W HPS about 12 inches from the tallest tip, and I thought that I should be able to get it like 8 inches without burning. Then I thought it might be a water issue. The plant needs to be watered every day, because it sucks it up quick. I transplanted it to a 2.5 gallon container last night, so maybe that will help..
Here's the Berry White looking nice:
And the Jack Herer also healthy, just younger -- Jack and OK vegged for a couple of weeks before flower compared to one month for the other two:
Thoughts?
