Well I got too lazy to change the res yesterday, but I finally got to it today.
Another member recommended a few changes so I'm going to try them out.
Things to change:
1. Transplant my 1 inch rockwool cubes into 4 inch cubes.
2. Reduce my TDS to 2/3 strength (app. 1000 ppm).
3. Reduce my feeding schedule to once a day.
4. Increase the space between CFLs and plants.
I have made all the changes and here are the results:
My remaining 4 after their transplant.
My smallest and 2nd largest.
Close up of my second largest. It's lost all of its bottom leaves.
Close up of the runt. Barely 2.5 inches.
This is the 2nd largest plant's roots. The most roots by far.
My third largest. No roots extend from the rockwool cube. All of its leaves are very skinny and curled down.
Root growth of my largest plant. Only my two largest show any signs of roots emerging from theirs cubes.
A shot of the family. Any ideas why all the broad leaves are dying and all the new ones are curled?
Top shot. What is the burn on the lower left-hand plant (my largest).
Here's a show of my res. Is that growth a bad thing? Is it just be the Dr. Hornby's Piranha and Tarantula (beneficial fungi and bacteria) that I added?
Here's an update on my cabinet. I got the light/reflector set up and it seems to be working very well. It's a 250w HPS with a 48v coaxial fan (140 cfm). I've read how people dislike coaxial fans, but this one seems to be handling my corners pretty well.
