looks much like a problem I'm having for the moment. I think it's mg as well

dude get some dolomite lime up in that biznitch. Not only will that fix your calcium and mag problems, it will blow you and then fix fox farms shitty acidic soil. 2 table spoons a gallon. Scratch it in and the overwater, with in 24 hours you're plants should be happy.

dolomite might fixit but fox is good stuff. sounds like a user error on your behalf.

Here is your problem, you feed her 3 times a week dude? Is this correct?

 

[greendream69]

hey stick i dont really keep track how often i feed her but its somewhere between 1-3 times a week it varies.

 

[greendream69]

i think there is 1 other problem that know one has noticed if you look at the middle pic of the leaf its starting to get a brown/purple on the edge i think i remember reading somewhere that it has to do with humidity.

 

[MynameStitch]

Purpling has something to do with phosphorus most of the time, what is your night time temps; I bet they are cold; cause that is the coloration they show when temps are cold or cool.

I'd agree with you DIGITALHIPPY if it wasn't for the MSM thread where you see other individuals with nute/ph probs. Foxfarms needs some type of ph up, whether you use there POM nute line or add some lime you're self, the soil as a medium by itself doesn't cut it.

i baught some espoma garden lime today should this take care of everything?

Pbp is low in calcium and magnesium. It's not surprising you need more. Most growers add cal mag plus at about 5 ml per gallon. Garden lime is ok too. But, it will raise your ph. If your ph is ok or high, this might raise it even further too high. So, knowing your ph is important. If your going to add lime, sprinkle about 1 to 2 teaspoons per gallon of soil mix and water in. You should stop adding the molasses. This will make a cal mag problem worse because it contains quite a bit of potassium. Ph adjust your fertilizer water after adding everything. Your soil mix will drift up or down gradually toward whatever ph you set.

Happy growing...hope things work out for you.

Have you flushed your plant out dude? You shold have done that and stopped feeding her so often, the only way you are going to fix it is by doing that.......

 

[greendream69]

i havent fed her in over a week and i flushed when i added the lime 3 days ago

 

[MynameStitch]

How much water did you use when you flushed her out real good?
Why are ya using lime if you have not even checked the pH yet?

You could be adding it to make the soil more akaline and not even know it....

You need to get a pH pen or some pH test strips that have a good pH range on them.....

Then go from there, if you already added it, hopefully you did not add enough to make a difference yet......

 

[greendream69]

hey thanks for the help everyone shes not looking very well so i think i am gana put her down so i could have some 4/20 smoke. does anyone know how this is gana effect the quility and yield of the buds??

 

[greendream69]

does any one know what kinda of effect its going to have on my buds??

Espon salt is just the stuff that was in the water before you took it out with the ph adjustment it will have no ill effect on your buds quality or quantity
