Acid dough first time (amateur)

JimmyOfTheJungle They've been out of the soil for 3 or 4 days, it's the cleverest way I could think of to keep them close to the light. I still haven't started applying nutrients.

JimmyOfTheJungle Today marks 2 weeks since germination, I just started applying Bio grow, it's winter in my country and the environment is freezing. I'm wondering if these temperatures will affect the growth of my plants, the water solution is very cold, I'm trying to fix it with hot water, I welcome criticism and advice.

JimmyOfTheJungle Third week since germination, I applied preventatives because I think the leaf has thrips, how do you see them? Advice and criticism are welcome.

JimmyOfTheJungle I had problems with the temperature, they took a long time to grow because of that, but we're still motivated with the cultivation. I moved the grow to a better-equipped room, the previous one was too cold.

JimmyOfTheJungle I left them for several days consuming water until the substrate dried out a bit on top, I really don't see any problems, I hope to have them until the end of the month and switch them to flowering. I followed the advice of the people who have been guiding me in the group and started making changes that were within my reach. Soon I hope to start measuring pH and EC, advice and suggestions are welcome.
