Dry amendmants are hopeless for being able to control the dosage...........they take ages to become available and there is a very fine line between too lttle and too much. Once you go too much, plants suffer and there is nothing you can do for 4 weeks or so.
Try liquid organic nutrients in future,...........much easier to get right and much more controllable.
I have seen so many problems with dry amendmants in Grow Diaries over the years.............can't work out why people still use them.
Not much you can do now, your plant will cope, but go very, very lightly with any future feeding.
It is very, very easy to correct a slight under feeding, but very, very difficult to fix an over feeding situation.
I have found cannabis prefers little feeds often, not big feeds infrequently.

For starters, raise your humidity. It should be in the 50-60% range at that temperature during flower. With the humidity so low, your plant is in over-drive trying to transpire which leads to the "crash and burn" you're seeing. You will also want to turn the light down 5-10%. You're trying to slow photosynthesis down to help rescue your plant. You need to do both of these as well as give your plants a good thorough watering with no nutrients in an attempt to flush out excess toxic levels of nutrients. You'll want plenty of run-off.
Your job as the grower is to give your plants what they need and then let them grow at their own speed in an environment that is dialed in to maximize growth. What it appears you're trying to do is what I call the "hotrod" approach ... The hotrod approach usually leads to crash and burn.

It will almost certainly be down to excess nutrients.

"Burn" spots on the leavesHello growers! I have what seem to be burn spots on the leaves of one of my plants. I've also noticed the tips of the plant are dry as well. The temperatures have been quite high so that could be why but wanted to check if it could be a deficiency. Any ideas?Week 6

Yellow leavesHi guys, unfortunately because of an emergency I had to leave my 2 babys with some friends for three weeks. At the bottom some yellow leaves and like burning signs. I don't think it's because of over nutrition. They didn't get any for three weeks. Might be not enough nutrient?5 years ago
