Gorilla glue losing its color

Nothing to worry about, just a couple of funny leaves. No plant will ever have 100% perfect leaves, 100% of the time. True nutrient lock out does not occur until pH drops below 5.5 or rises above 7.5, so it is unlikely to be that. Congratulations on growing this strain, I have multiple times and she is a real killer trichome producer and has a "knock your socks off" type of high and I am sure you will be mightily impressed with her. Just don't pick her too late, 90-95% brown pistils will give you the knock out effect, waiting too long and leaving her until there are 98-100% brown pistils and she becomes a CBD sleeping pill! Don't worry about trichome colours, pistils are more indicative of plant health and it is plant health that is responsible for trichome composition. Once a plants leaves have been damaged by a nitrogen over dose, they will stay damaged/burnt and will not recover, so it can't be that. As I said earlier, it is pretty well normal for the odd leaf to look a bit funny every now and then, it is when you have many/most leaves looking funny that there is a rel problem/issue. At this stage you do not seem to have any disease or nutrient problems, just a couple of slightly less than 100% perfect leaves. Hope this helps, Organoman.

Hey man. New to grow diaries but a fairly experienced gardener. This picture is telling me a couple of things... Very minor issue but worth keeping an I on for the next week or so. 1. It could be just some wind burn from a fan being to close. 2. PH might be falling up or down out of range to uptake proper nutrients. To test the soils PH with out a proper PH soil test kit simply water with a PH of 6.5 until enough water comes out where you can test it. If the water isn't in range, You may need to adjust the waters PH a little more carefully next few waters. 3. Or it could also simply be recovering from a previous small nitrogen overdose and coming back to normal color. Hope this was helpful! Happy growing!! ✌️
