Help with growing PRoblem!! Possible slow death

[Grow Green]

Hi I am having a problem with my plant. I am a first time grower and am having a serious problem that i cant pinpoint. I think it is a mixture of calcium and magnesium deficiency but i have been feeding with micronutrients all the time. can someone help and reaffirm this or help with a diagnosis.

The symptoms are leaves dying at the tips and browning and yellow like a burn but worse. the leaves then brown to a grayish brown sometimes and the leaves twist and cringe. The leaves are not fresh feeling or look fresh and are easily crunched if that makes sense. the first symptoms starts with accumulating dots on the middle vein and then spreading and then slow death and yellowing of the leaf.

here are pictures

In the picture of the individual leaves you cant really clearly see the little spots but they are a clump of dots.
Shoot me questions and please help!


thanks for the help

Please answer all the questions in the How to ask for help thread. Nute schedule, light, temps, humidity, about a dozen other things. It is really hard to make a diagnosis without all the facts.

Here is the link to the post Maer mentioned. Also the close up pics need to be in focus.

What is your nute feeding schedule? Your pH is too high, but how did you measure your pH? Seems like a really wide range.. Dolomite lime will actually buffer your pH down also to about 6.5 so i would top dress with about a cup of dolomite lime to handle your pH issue. Mix it thoroughly in the top couple inches of soil then give it a good water with straight RO.

Isnt sweet for flower? maybe I am thinking of another product but I thought that was a carb supplement.

Do you have a fan blowing on your plants? Is it oscilating? This looks like it could be fan burn.

You have been vegging for 4 months? Hmmm, I had some plants that were vegged for 4 months and they had massive nute buildup in the soil, if you are using full strength nutes (I did the same 1st time around) I would say you need a flush badly. And you also are using too many ferts... Also when do you foliar if you do it lights on it can cause burn, but I know there are formulations that can be applied in the light. Sledgehammer from FF is a good flush solution, some people swear by straight RO, who knows the real answer.

Do you have your pots raised off the ground? The bottom of a smartpot can get moldy if not on some sort of grate or something to allow airflow. Also how tall are your plants? You may not be getting light penetration all the way to the bottom.

Looking at your lower leaves I see some have the dreaded CLAW! This is one of two things, pH or over nute. Probably both in your case.
