How do you know if your weed plant is getting enough light?
Cannabis plants will show a number of key signs when they’re getting too much light. The most obvious indicator is leaf burning. This typically causes yellow leaves at the top of the plant directly under the grow lights. While the inside veins stay green, the leaves take on a yellow, burnt look.
What nutrients does weed need in veg?
During the vegetative stage, the plant will require a base nutrient that is higher in nitrogen and lower in phosphorus and potassium. A base nutrient represents the main component of any fertility program (feeding schedule) and should contain the majority of essential elements needed for plant growth.
Do weed plants stop growing?
Once the plant starts receiving less light per day (from 18 to 12 hours), its growth will halt and it will enter the flowering phase.
How far should the light be away from the weed plant?
In general, you’ll want to hang your light no more than 12″ away from your plants. – Remember: after 12″ fluorescent lighting loses its power, so make sure you don’t raise it any more than 12″ above your canopy otherwise your plants aren’t getting light energy.
Can a plant get too much indirect light?

Do you need nutrients for weed plants?

How do you tell if your lights are too close to your plants?
The first signs look like thin outlines on the outside of the leaves, so if you catch this quickly you will have a chance to avoid further damage. If some of the leaves start curling up, it might also be a sign that the plant is too close to the light. Good ventilation usually also helps with this issue.

- Yellowing may be noticeable in the leaf tips first.
- Leaf yellowing may not affect the leaf veins initially.
