👉The plant is looking vibrant and seems to continue to flourish, albeit seemingly taking its sweet time. Seems like its in slow motion compared to its veg cycle. To see changes you have to look close or compare pix from a couple days apart. The flowers are getting more aromatic, and has the typical wonderfully sweet lemony stank think going on. Super frostiness as can be seen in the pix. The trichomes are totally illuminated by the lights used by my camera (flash and an LED worklight). May rival the gorilla glue for frosty overload. No new nutrient issues have shown up. The burned tips remain and I hope my good fortune continues. It developed a lot of smaller branches and will have lots of pop-corn buds. Shouldn’t be too much of a big deal and will add to the hash production in the end.
👉My time has been slightly curtailed due to work demands and I hadn’t been able to mule any water home until today. In the absence of the 98% pure water I get from a medical facility, Ive been using tap water run thru a 1cf carbon tank. The tank dechlorinates the water, I use it for my outdoor patio garden of herbs, peppers and single tomato plant. The pure water was 4micro siemens conductivity, the carbon tank water is 45micro siemens (tap is 245). The carbon tank water is far less reactive. This is evident when adjusting the pH. A batch made with the RO water needs just a few drops of pH down to reach desired pH. A batch made with the Carbon tank water takes a couple droppers full. Ive also noticed that the plant may not be able to absorb as much of the nutrients with the carbon tank water. This may be pure anecdotal stoner’s observation, but the EC of the run off has been almost impossible to get down to matching inflow. Its staying 20+ and shoots right up to 30+ each day. I started just giving double volume feed water and no low EC solution. Partly because I broke one of the jugs which I used for mixed solution batches. The high EC run-off may also be a result of the dried nutrients on the side of the pot being washed away more due to the higher volume of inflow. So I may be chasing my tail on this by giving full strength nutrients at double the volume with double run-off. Good thing is that you cant over water in coco unless you try really, really hard. 2 fertigations in one day isn’t even close. The plant is drinking more each day as measurement of the run-off compared to inflow shows the saturation volume. I fertigate in two steps when doing high volume, divide total volume in half and feed half and then measure the runoff. I then feed the second half and again measure the run-off. The difference between the inflow and run-off is the amount taken in by plant and lost to evaporation. I split the total in half to get a more accurate measurement of saturation level and plant intake/evaporation level. I then use that information to help predict how much solution should be given at the next fertigation event. This coming week I will be switching to the late bloom solution mix recipe for the GHE drain to waste chart. I mix it to the upper level strength for desired EC. The difference is slight. It removes rapid start from the mix, and reduces others slightly, except for bloom and micro. I should be able to return to the RO water for the rest of the grow.
👉I haven’t taken an actual measure of the height this week, but at tonight’s fertigation I measured the tips of the center colas were 15” from the light, so I will raise them in the morning back to 18”. The plant could probably take being fairly close to the lights, but I don’t think its nessessary to risk light stress if I don’t have to. There is still 6 more inches of verticle room to raise the lights. If the 99 decides to just keep going slow and steady, packing on bud-age, I can also spread the lights outward and angle the lights to give the two top colas more space.
