help

need help. I'm a new grower and don't know what is wrong with my plants. I grew in miracle grow soil because it's all I could get. I'm being careful experimenting with notes because of it. My leaves are turning yellow, and dying but the veins are still green. I have advanced nutrients 3 part PH perfect fertilizer but don't know how to use it with the miracle grow soil. My plants are almost 5 week into flower and have been slowly dying for a while now. Could it be a magnesium deficiency?

The plant isn't dying - or at least iyou should be able to stable i.e. it enough to get it finish. No idea what the real problem is.

Is it getting any mag. from the soil? If not that may be the problem. Bat quano will give it nitrogen without burning it if it's a problem in that area...

I'm thinking the plants may have used the nutes in the miracle grow soil. Which is why I've been experimenting with nutes but they are not helping. Seem to be causing more trouble than anything else.Think I'll get some Epsom salt on the way home from work for the magnesium. See if it helps any. Just flushed plants last night. We'll see if that helps any.

I think if you give a small boost of nitrogen you will be ok. The plant on a whole looks very healthy

Yeah she looks a little hungry, but at week 5 I really wouldn't start throwing nutrients at her. I would put about an inch or two inches of fresh soil on top of the existing soil, this is called topping off. Then you water it in. This gives the plants a little boost of nutrients, the same nutrients that they are used to having. But without overdoing it at this late stage of the game. You will notice a little bit of improvement and then she will slowly fade until Harvest.

Best of luck.
Peace

ok I'll try that. Along with a little Epsom salt for the magnesium.
