What? No it's not. It's an offset of transportation from low humidity misbalances for photosynthesis, the plant is getting overwatered. When humidity is to low the plant uses large amounts of water, that causes the plant to bring in to much water in to fast of time. Cannabis likes to be dry more than it is wet. If u have to water everyday you are in to small of a bucket causing you to overwater. Plus his low humidity is causing the plant to use even more water to transpire correctly sucking even more water.
Solution: Switch to a bigger pot once Your frequency of watering is at every 3 days. You want to be around 4-5 days between waterings. Slow the transportation down by raising the humidity to match your temps or use a vpd chart. Example 80°F requires humidity to be 60% RH even during flower. 90% of green tops is bucket size to watering frequency (Overwatering)
This will eliminate his green tops.
