First Time Grow from Clones

Hey Everybody :) I'm a First Time Grower on a short Budget. I more or less stumbled over two beautiful clones of Gorilla Zkittlez with no preperation done on the topic of growing. So I just started sitting them into a glass of tap water to see what is possible if I deal with no pro setup, but instead try to get the information right and give the girls enough time :) A few days later the first roots started to spread out. Purerly white and healthy looking. But soon I could recognize a slowing down of the roots splitting and recognized leaves starting to yellow. After reading about the topic of possible nutrient lockouts due to pH issues I found out about the tap water in my city beeing at around 7.5pH. So i tryed fixing the numbers by changing the water and adding some lemon juice. The deficiency sings did not spread further, but on one of the girls the speed root growth was thrown back. I rooted the clones on my desk with little direct sunlight and was able to get 4 15W grow leds at 4000K for the Veg by a friend. Since I got an good deal for a Driver, the plan is to upgrade to an DIY setup with 288 Samsung LM301b 3500K at max 150W later on. After 3 weeks from cutting the better recovered had developed an impressive root system and i noticed first sings of new growth on her top, so it was time to think about soil. I settled for 11l bags to go with first and then, since I'm planning on a long veg time, migrating to 39l. For soil i mixed BioBizz lightmix with 1/3 coco coir and added roughly half a teaspoon of the Myko Powder. The powder was also added to the planting bed into that i transferred the clone. I soaked the soil in plain water since the pH of the coco was at 5.5 and i wanted to get a bit higher to give the fungi better conditions to work. The plant lived in well and grew wider every day with no sings of over or underwatering for 10 days. At this day (Day11) I gave the plant its first watering with 250ml of water + 0,25ml/L BioBizz Grow + some Myko Powder. I saw that the clone had developed a second top at the frist branch so i gently bend down the dominant one to allow it to catch up. On the same day I put the other lady in her bag too, because the roots showed a little browning the days before. But i was in a hurry and and it happend.. I broke the biggest root near the stem 💩 I fully realized this the next day and in an attempt to save her i putted her in a smaller pot to have better control over humidity of the soil. She started showing small sings of recovery the next day, but I'm not sure if i will be able to rescue her... But there are good news from the other girl 😌 She's looking very healthy and today (Day15), 4 days after the last watering i gave her another 250ml of water+ lemon juice (not a long term solution but I'm not really sure yet what else to use). I also gave her the first real training by tying down the dominant top. I plan on topping it back in the next weeks and eventually take the clone to replace the other lady. That's it for now. Have already been learning a lot from the experiences the community is sharing so every comment is welcomed, like i said this is my first grow and its a rocky journey :D
