3x Rainbow Zkittlez Clones [First Time]

28.02.2024 mixed new fert water with 70% strength of feeding chart, EC 1.6, runoff was 1.3, gave around 1L per plant +-, plants look good, a few of the leaves of two of the plants have their very tips crisp/burned, not sure why? maybe a deficiency, because I doubt it was overfeeding, tho im not sure cuz starting EC of tapwater is so high..idk! 01.02.2024 watered the plants ------------------------------ I began to realize that 4 plants was gonna be too much in this tent, so the fact that the fourth plant was developing slower came in clutch. Didnt have a fourth 3L pots back then, thats why it as in a smaller plastic pot. ------------------------------ 03.03.2024 cut up and flushed the 4th one down the toilet. The "autopsy" was interesting, the rootbal was quite advanced, the plant is a lot more robust than i previously thought. I mixed new fert water at 70% strength using around 9-9.5L instead of 10. Repotted the plants, the rootballs looked good, the roots reached the edges but not too drastically like with the fourth one, i think it was a good time to repot. The 7L pots seemed only minimally larger than the 3L ones, from the width at least. Watered around 2-2.5 Liters per plant, had adequate runoff. I plan on letting the plants rest from the replanting, and keep an eye on the nutrient situation, making sure the defficienies are not present anymore. If they seem good after a week, i might initiate flowering phase, 1 or 1.5 weeks, we'll see.
