yes they are outdoor in soil and have been since the beginning. They only had nutes once, at 10% strength of the indicated solution strength on the bottle, it worked out to 1 drop of feed per 250ml of water. i always check the ph of the water is at 6. The air temperature is around 27 degrees C, they have been getting a few hours direct sun in the morning and again in the afternoon, for the strongest part of the day they are in the shade.
How do i check if the root system is in that range ?
