Obviously, when the lights are on, the plants can harness the photons of light and through photosynthesis, harness the nutrients. Now, they’ve got quite a high CF level in their buckets at the moment and they’ve got no light in order to utilise it so that could be again, the reason why they’ve slightly curled, but other plants; these big ones that can obviously tolerate more food because they’ve got more mass are showing no signs of leaf curl or slight over fertilisation. And as I said earlier, you’ve really got to do what’s best for the mean average, so if the odd one does it, but the majority don’t, then well, what can you say, don’t worry about it.

You rock on and continue, but making sure that if they do show signs of this particular type of leaf curl, then you ease back on the amount of nutrient and before I go home today, I might well keep an eye on it for the next hour and if others start to show the same characteristics, then I’ll probably lower the CF down to 20, but at the moment I thought I’d give them a right kick up the arse and give them as much nutrient as they can possibly handle.

     I’ve also tweaked up the CO2 slightly, the reason being is because we’ve now implemented a little blower in the very far corner to blow across the canopy...
