day 11 from germination 5 litres to the pots with different ph between 6.2-6.5 with 0.5 MLG bio grow for litr. day 12 from germination its my bad day I noticed that my plants are very stretched and Fragile; compared to their peers that I saw on the site, are very behind. I think the reason is that I got a 110 watt Amazon lamp, put it 100 cm away and gave them a lot of fertilizer and water. To solve this problem, I ordered a spider sf 1000 and i gathered the soil of pots from the side and poured it around the stem (And I brought the air to 20 c°, which I do not know is correct or not). Current situation: Plants are giving new leaves and I see a tendency to grow in them. My question is, are my plants very backward for 12 day after germination? Do you think that if plants are not going to grow enough and their start flowering quickly when their are still small plants, it is not better to throw these away and plant new seeds? Does it cause the amount of yield to decrease?Or I still have a chance to fix it? There is a way to increase their growth period? After I buried the stems and changed their height from 14cm to 8cm, can the stems have new roots? And that now a few cm empty flowerpots do the roots have enough space to grow according to the photos? Thank you very much for your help. day14: Today is the 14th day and the last day of the second week. Today I installed the fan and ventilation and a new lamp arrived Spider Farmer sf1000. Very high humidity, someone can help me. And that there is a way to grow four plants with this lamp? Do not miss today's video.
