1st grow Auto Gagarin from axxseeds (RU)

2 week starts really bad at 7 day you can see, that 2 plans get lower their leaves, i dont know why, becouse i overflowed only one plant. Also both plans was transferred to bigger pot, this is stress situation, and at least hygrometre dropped down on 1 plant. Growth has slowed. May be i must add some nutrients, what do u think? On 11 day, 1 plant starts to grow!! Im happy, my bad was with water shortage, and strassed transplant. I started slowly add water to plants with nutrients. Temp started to grow, now it's +30 °C day, and +24 °C at night. Humidity ~ 50%! Day 13: the bigger one turned pale, and 1 leaf had a brown dots. I think this is sunburn, and i raised lamp from 12sm to 21 sm. Day 14 update: only on 14 day i opened for myself, that i add not enough water to plant! Bag takes 1 litre! After that small plant hands up leafs. The bigger one looks really good and healty.
