hey, so due to a hot spot this plants bottom leaves were burned early in its life. I also made the mistake of trying to introduce a a weak solution of some grow big so that may be causing this too. I flushed earlier on but not after ive transplanted to the new pot. Also, there has been times when the temp. has gone above 100 degrees so in combination of heat stress, a slight over nute problem, and being burnt, might be causing this. But i was also wondering could it be a phorsphorus deficiency?
The leaves turned yellow/brown first, then the yellow starting turning a black color and the leaves got crispy. The tips on the leaves above are just beginning to show these same symptoms. Some of my other plants have slight heat stress/over nutrient problems but none turned black like this one.
these pictures are about 2 days old, and the black has spread a lot and so has the yellow :/. you cant really tell in the picture but the edges (now about 1/4 of the leave though) is black/grey
