My plants are not doing so well after yesterdays nutrient change. It dropped from 850 PPM to 780 PPM and went from a 5.9 ph to a 6.3 ph. I think I'm going to mix a new solution today at around 1000 PPM or so and see how it does. The leaves are yellowing and curling at the top as you can see in the pictures. I assume this is due to my nutrient change? Any input?
I did a nutrient change. I had it set at 1000 PPM and 5.9 PH. After changing it out I realized I need to add more water, so I added more, but had to leave right away so I couldn't check on it. When I came back the next day the plants were looking great. It was not at 510 PPM. I added a little more and it is now at 595 PPM and 6.1 PH.
Unfortunately because I was using 1000w total for a few days a couple plants didn't get as much light and are growing a little slower. I figure I'll flip to flower when the larger ones are ready and have a reduced yield on the smaller ones. I added a foot to the height of the tent as well and heat does not seem to be an issue for the time being
Any advice on training this scrog? There are HUGE fan leaves at the top that make it harder to train the plant. When should I start trimming below the canopy?
