test-grow

On day 19 I trasplanted pro plant into 8 liters pot, on day 20 I did it also for base plant, both had a very good root mass encircling the entirety of the small pot they were in, I noticed both plants' leaves were curling on the tips and starting to burn (I think) so I dialed down a bit the nutrients to 600ppm. Pro plant is exploding in growth and doing very good, base plant is behind, not much in development, since they both have 5 nodes, but rather in size, pro is much bigger being 12cm tall, while base is much bushier being just 9cm tall. Temperature got higher at 24-25 C because of the lights now being at 75% intensity, they are led but nontheless they are so damn hot. On day 25 I realized I made 2 big mistakes and I'm furious because it's not really my fault, especially for the first mistake which is: I started noticing calcium deficiency and I went again in the rabbit hole of "do you need to add calmag to canna coco nutrient line even tho it already have calmag in A+B?", and I say again because I already knew, I just forgot that indeed yes you do need to add additional calmag if you use RO water because apparently canna coco line is designed to work with tap water and even if you can chose RO water from the nutrient chart calculator, and they spam everywhere that canna coco is a complete line and you don't need anything else, they don't tell you you need to add calmag, they even have a calmag product, they could just add it to the list of nutrients you need in the feed chart if you use RO water but no, they tell you in a small FAQ question if you go really deep searching for it, absolute BS. The second mistake is about EC in the nutrient solution, both plants were showing signs of nutrient burn, and it just could not have been only because of the calcium deficiency, so I did a light flush with 0.5 EC and started researching again and I discovered that I wasn't properly taking care of my pH/EC tester (I did not know you need to store it in buffer solution, it wasn't mentioned in the instruction pamphlet) and it was not well calibrated anymore, both for ph and EC, it was indeed a very cheap one, so I discarded it and bought the milwaukee EC60 PRO and the milwaukee PH55 PRO, with the relative buffer calibrating solutions and I confirmed that readings were far off, I basically was giving the plants up until now, 1.6 EC of nutrient solution 💀💀.. but to be fair, to me everything was fine since run off readings were not showing something was off and from the canna coco feed chart calculator, out of the 3 possible feeding strenght (light feeding, normal, aggressive feeding), I was using the light feeding, and the chart said 2ml of A and 2 ml of B per liter of solution and that combined with the other supplements was going to give me a 1EC solution which is what the pH/EC tester was giving back, so again, to me there wasn't really something off up until the nutrient burn signs.
