OK. Its time for a quick update. I am at day 42 today since I started the seeds. I've upgraded to a 400 watt MH fixture and also rebuilt my Hydro system using all parts from HD. Last Friday I took the rockwool cubes and planted them into 1.5 gallon pots. With the pots in the tray they get fed by flood and drain. The holes in the bottom of the pots allow the Nutrient solution in to the pot and eventually drain back out. I like it like this because I can move the pots around, take them out or whatever without having to deal with loose clay pellets.
Anyway, Here are a few photos as of day 41. I am running: a PH of 5.9, PPM of 880, Temp. is at 77/79 day and 67 to 70 at night. Humidity is low and I am working to get it up. Its at 36 to 38% even though I am pumping a gallon a day of water throught the Humidifier. Plants don't seem to know the difference thought. They are taking off nice with alot of growth everyday. There are turning into tight little bushes. To many leaves and nodes to count anymore. YIPPIE !!
Even though these photos were taken only 3 days ago................the shorter plants are already as tall as the tallest is in this photo. I have one that seems to be outgrowing the rest fast. I'll probably end up tying it down or even topping it later.

A few days ago I was worried about the leaf yellowing problem. I did my research and got it handled. I have switched from Fox Farms Grow Big to the 3 part General Hydroponics nutes. Along with GH misc fertalizers and supplements. I am way happier with the GH stuff since it allows more control over individual NPK mixes. Plus.................my babies are way happier too. I think It was a good move....................for me.
Here is a photo of the yellowing I was seeing. They are still yellow but it has not spread at all. The GH stuff helped me get it right. Out of 9 plants...............5 had some yellowing on the lower / older leaves. Like I said.........I got that fixed. (Potassium deficiency)
The yellowing:
I've pretty much learned to just leave them alone now. I messed with them alot and probably slowed their growth at the beginning. Plus it helps that I have the nutes stabilized.............finally.
Till later.
