The tips of the new leave are looking different on only 4 plants what is this ??? Sent from my iPhone using Grasscity Forum
Looks like the beginning of nutrient burn, maybe even heat/light, but can't tell for sure under this spectrum.
I don't have another photo at the moment but the plants are really dark green and these tips are very very bright light green Sent from my iPhone using Grasscity Forum
And if it is nute burn how can I stop it , can't be the heat because the temp is ok and the light is a good distance away Sent from my iPhone using Grasscity Forum
Dolph say it may be nute burn, probably would agree, but it is really hard to say without a natural light photo.
