Why seedlings turned purple and grow poorly: tips that can help save the harvest
Usually the seedlings should be green. But it happens that they start to change their color to yellow or purple.
Such changes can destroy seedlings.
At the first changes, it is worth considering a lack of nutrients, which is why the seedlings change color and begin to grow slowly.
Why does this happen?
The seedlings were affected by disease or pest.
Perhaps the seedlings are affected by lighting - phytolamps. To fix everything - the seedlings need to be set to normal solar radiation.
The seedlings may change color during hardening. The temperature has dropped to 15 degrees. If the temperature drops by another 5 degrees, the seedlings will stop growing, phosphorus will not be absorbed, and the root system will suffer.
Fertilizer containing phosphorus and nitrogen will help correct the situation.
