On August 18, they began to see their growth ,and saw the cotyledons. I have started using B52 foliar spray to strengthen vitamins absorb nutrients quickly.
On August 21, it was the third day that the leaves began to grow. The growth was satisfactory. But some plants look like the tip of the leaf is slightly bent.
It might be stressful from the weather or from adjusting the PPFD, my light power might be too much. Before that It began to stretch so I increased the brightness.
On August 21, the 6th day of veg stage , there was only 1 tree . She was shocked maybe the weather might be too hot in Thailand.
Since August 18th, I saw that it was stop grow. But now I see that it's starting to grow new cotyledon leaves ,and seems to be stronger.
It's almost the second week. The plant is so weak that it has begun to produce new leaves.
So I gave B52 supplements and they can fully deal with tree stress.
