The vanilla Kush plant now has 9 even nodes. The FIM (feel free to ask if you don't know, I'll be happy to discuss it here) job from the other day is showing results. All the nodes below the FIM are now branching. I'm debating how I want to raise this plant. They are supposed to be good for ScrOG grows, so I may end up doing that. I want to get some cuttings from her first, but that is 2-3 weeks away. I bumped her up to 425 ppm. Nice looking plant with beautiful colors in the stems and stalk. I'm going to like this pheno..
The pineapple express plant was hungry, very hungry. Her ppm were down to 575, from 1000 ppm. I bumped her up to 1200 ppm and adjusted the PH from 5.1 to 6.0 because it appears the newest growth is lacking iron. The tips are fluorescent green/yellow and the leaf end were slightly twisted, a sure sign of a too low PH in the reservoir. The last time I topped it off was fresh water only, so the buffers were light. One of the easiest ways to start to diagnose plant problems is to observe where the damage or problem is.
If the problem appears at the top of a plant, that indicates a micro-nutrient problem, such as Boron, Iron, Copper, Zinc, etc....Those nutrients aren't as readily available to the plant from the older growth like macro-nutrients such as Nitrogen or Phosphorous are. Most commercial fertilizers made for hydroponic applications include the trace minerals and micro-nutrients; however if the PH is too high or too low, those nutrients are easily locked out and the plant can't access them. Take a look at the picture below....
Notice the fluorescent tips on the new growth, but not the older growth below. I can rule out N, P, K as suspects because of this fact alone. The leaf below is healthy and lush. Macro-nutrient problems tend to start at the older growth, down below, and work it's way up the plant if not corrected. Micro-nutrient problems are just the opposite. You'll notice in both pictures that the new growth appears slightly distorted and twisted. This can be caused by a lack of trace minerals needed for healthy generation of new tissue. At first I suspected Iron(Fe), but after looking at my PH and my chart that I've included at teh bottom of this post, a PH of 5.1 won't lock out Iron, however the amount would be reduced. What is locked out is Boron and Manganese, two very important nutrients for new growth. By adjusting my PH in the reservoir back up to 5.8, the plant can access what it needs to correct the deficiency.
Overall, the plant is about 16" tall now, with many branches. I took 15 cuttings Monday night and today, I could easily take 15 more. I removed a lot of leaf tonight and the light is getting through much better now. I want the skinny branches to thicken up a bit before I take them next week sometime. After taking more cuttings, I'll veg for about another week and throw over to 12/12...
Have a good night everyone.
