i’m learning DWC

Hello everyone! After a few unsuccessful attempts at hydroponics, I am facing challenges once again. However, this time I believe I will succeed. I want to thank everyone who is willing to inform me and help me learn. I appreciate your support and look forward to your assistance. March 10th, Monday (Germination) * Seeds were placed in water. * Only one of them sprouted on the night of March 10th. March 11th, Tuesday * Transferred the other seeds to root riot and placed them in a warm area. March 12th, Wednesday * Filled the container with reverse osmosis water to wait until tomorrow afternoon to ensure there is no chlorine. * r-DWC: * Filled with 40 liters of water and 45ml of H2O2, running. If there is chlorine and fungi, they will be gone by the evening. March 13th, Thursday * Rinsed the clay stones again, pH adjusted to 6.0, and checked, pH remained stable. Will rinse again with 0 ppm and pH 6.0 water. * r-DWC: * Transferred the seeds. * Made a dome to prevent light from the sides of the clay stones and covered them. * Added 10 liters of water, totaling 50 liters. * Water level is 5cm below the net pot. * Added 10 ml of pro roots to the reservoir. * Two Blue Dream plants were dry at night, watered them with reservoir water. March 14th, Thursday * Fed them with spray after the lights went out. March 15th, Friday * r-DWC: * Top-fed with reservoir water. * Leaves of the 1st and 2nd plants are starting to turn light in the middle. If it continues, will transplant to soil. * Added 5 liters of water with pro roots, totaling 55 liters in the reservoir (5 liters = 1ml pro roots, ppm 30, pH 5.7). March 16th, Saturday * ALL: * Fed with spray before the lights turned on. * r-DWC: * Top-fed, avoiding wetting the root riots. * Plants #1 and #2 have sagging leaves and light-colored middles. * Plant #2 was replaced with the one tested with voodoo juice, and the hydro one was put on a paper towel and squeezed the root riots by hand. * Added 15 liters of water, totaling 70 liters. * Added voodoo juice and sensizym. * First fertilization given at 1/4 dose (70 Lt / 5ml) base nut + cal-mag. * PPM 110, pH 5.9 * Removed the top clay stones of plant #1 and placed a paper towel for the root riot to dry. * Water level is 3cm below the net pot. March 17th, Sunday (1st week) * Swapped my pro root experiment with plant #1, wrapped it in paper towels, and left the roots in the dark. Will check in the morning to see if the issue was from top feeding. * Dried leaves of plant #1 and moved it to the dark reservoir. * In the afternoon: * Started to plant the dried leaves of plant #1 and #2 from yesterday. No issues with plant #2; it continues to grow. Plant #1 needs to progress a bit more; it's lagging behind.
