75 Days Old, 32 Days Flip, 18 Days from First Flower - Yellow Leaves
The issue of yellow leaves appears to be getting worse. A couple of days ago I added growth nutes to increase N but it's too early to see if it's helped at all.
The room the tent is in is dark so I had to turn off the LED's and use flash
You can make out the spread of discoloured leaves in this picture better, even though the LED's are tinting things
During veg I only removed a few leaves under the scrog net, so there are probably more fan leaves than more experienced growers would have at this point. All the yellow leaves are lower on the plant and none high on the canopy.
Is this normal at this stage of development or should I be taking corrective action and if so, is adding extra N via grow nutes the right way to go about this?
For a bit of background; all nutes have been given at the minimum suggested dose, so it's very unlikely to be excess nutrients. CalMag has been given on most feeds at the rate of 0.75ml per litre.
All feeds have been to the Old Timer schedule at half the maximum recommended dose and if anything they have been a little under-watered, getting a soak once a week. Through the week they get 1 litre of water every other day.
Water is pH adjusted to 6.5. Out of the tap it has settled at 7.2.
I'm hoping some yellow leaves is normal on very lightly defoliated plants.
Any advice would be very welcome at this point; I'm somewhat concerned.
