Grapefruit [Day 62 - Coco - 7L pots]

Tuesday I've cut one of the Grapefruits today , day 58 from seed 😎👍 She is ready yet but I could have wait longer before harvest , the real reason is that one bud is starting to get moldy inside so before I loose my crop I prefer to harvest. The second will still be growing under the MarsHydro TSL2000 so I'll report the grow until harvest. She is a bit slower to flower and also a bit more sativa looking than her sis . Friday The biggest one is the only one that remains and ... she is pushing a lot of new pistols like if she wanted a second bulking up phase 😍 that strain is pretty amazing to grow as she have different harvest window and each one could be the good one for you 👍 I feel like this one will remains another week into the flowering tent before cutting. I want that weed to have a lighter effect that my 1st harvest ✌️ Saturday I wanted to talk about the colors of the leaves . Leaves are showing some ph fluctuations signs and also some cal/mag issue. I can't really get why I had these ph fluctuations and why these fluctuations has marked the plant, I feel like my ec range was around 5.7 / 6.2 so that 0.5 difference is my fluctuations range 🤔 The calcium issue is slight but visible and I also experimenting a potassium deficiency visible by the burning tips + yellowing & rusty edges + the little dots . Except for the ph that I am checking everytime, the others issues are my fault , I did have that plant a kind of N boost by using a 6-5-4 NPK nutrient to counter balance a slight N deficiency 2 weeks ago and unfortunately that nutrient is Cal/Mag free which may have caused my deficiencies but also the PH fluctuation as I noticed that an extra cal/mag was helping the ph not to fluctuate that much , it generally does freeze the ph around a certain value ( that value is 5.9 ph in my case ) Of course it's only a supposition so if you can explain the science behind it please explain it to me in the comments section 👍🙏 Sunday Well after 63 days and with 100% milky trichomes .... the last grapefruit has been harvested 🌱 I had the choice to push an extra week or to cut and I've cut . See you for the harvest/ smoke report Thanks to everyone who has helped me during that journey , I hope that the stuffs that I've shared with you will be helpful or at least will not be useless and I wish you many harvests 👍😍😘😋🙌
