Female Seeds Lemon Kush

This weeks feed proved to be too much for the girls. I followed the feed chart to the letter this time which it indicated the ppm to mix to 1200, which isn't high by my standards. In the past we were mixing hydroponic solutions upward of 2400ppm. Anyways, i highly highly highly recommend installing a security camera in your tent. You can hook it up to monitor on your phone and you can check in on your plants 50 times a day if you want with just a tap or 2 on your phone screen. Reason i advice it is because you get a really good grasp on how your plants look, so when something looks slightly off you will know right away that something is up. I knew my girls were dosed with a hot mix of nutrients, and i found that out when the lights were off. Because i have night vision on my cameras and i could see the closest plant to the camera, that it's leaves looked different than usual. The leaf tips were pointing up in a wavy upward pattern that was different from how they normally looked, so i knew something was up. When i went in, and checked when the lights turned on, my suspicions were correct. And based on a issue with plant #6 which we determined it to be nutrient burn, the signs and symptoms were the same. So i did nothing lol. I just said fuck it and left them alone as sort of an experiment i guess, but also partly because i just did a big flush and it was a bitch and i don't wanna lift the pots off the bases again and fuck up the wicks underneath lol. So i monitored them closely and made sure it wasn't progressing severely and killing them. They are damaged yes, but still truckin' I Let the soil dry out and then i watered in 2 liters of 6.2 pH calmag in each pot yesterday. I'm hoping that the plants gobbled up a bunch of the nutrients that was burning them, and that adding the 2 liters of calmag to the soil will perhaps provide a light flush, and also free up any remaining salts from the previous feed. I'm hoping that it will provide a balance, because i really don't want to flush again. There is some debate on whether or not calcium is even needed during flowering. Calcium delivers nitrogen during veg, but in flower, the plants don't need a lot of nitrogen, or calcium, so there's some debate on whether calmag is necessary during flower. I add it anyways just in case, but the science suggests otherwise. Anyways, some plants burned worse than other's. Some plants hardly show any damage at all. This is why i have always loved water culture, because i know exactly whats going on in my mixture and my root zone. In soil and coco, who the fuck knows from one day to the next? Oh, and 1 last thing. The feed chart i am following does not include a calmag supplement, and, i am using green planet ocean magic instead of the IPP Sea Storm additive that belongs in the line (i ran out). So the calmag is increasing the PPM and the green planet ocean magic i don't know how big a difference there is between it and the Sea Storm additive. Just things to consider. I do have a PPM meter. It's brand new in the box. Maybe I'll whip it out and calibrate it and test next batch. I usually never bother because the feed charts provide the PPM value of each weeks mixtures. But since i am adding extra additives and different brands of additives, maybe i'll just check. I calibrated my pH pen yesterday evening and it was off by a little bit, like 0.2 on the pH 4.0 test it read 4.2, and the pH 7 test it read 6.8. All calibrated now. I have to admit, that i am still not 100% sure it is completely the fault of the nutrient's being hot. So here's why.....The Coco i use is the Mother's 70/30 coco perlite mix that comes in 50L bags. It's washed and buffered to 6.8 pH. I water in 5.8 solution, come back next day it's 6.8 in the soil. Lowest i ever got it on my soil pH reader was 6.6. So, here's the question....pH fluctuation damage can look like magnesium damage, except where magnesium deficient leaves create inter vein chlorosis, pH fluctuation creates Necrosis between the veins. Now, being that this Coco stubbornly wants to sit at 6.8, I'm wondering if dumping in a 5.8 to 6.0 solution could be a drastic, and wide enough swing in pH, to freak the plants out and cause the issue. OR, could it be a combination of the 2??? And Apologies, i took a video on my phone for this weeks entry to the diary, but this website refuses to work when i try to upload it, so that's unfortunate. I'll try again but it's not really cooperating. And if you like the Camera corner shelves, I got a 2 pack off amazon for about seventeen bucks. I don't recommend the ones i have though because they have rubber clamps and they grip like a mother fucker to the metal poles and are very difficult to move up and down when adjusting the height.
