What's the problem?

Needs more Mg.

Needs more Mg.

Do you think I should start using calmag or topdress with dolomite lime?

 

[Capn-Crunch]

Add calmag

 

[Capn-Crunch]

Or, add Epsom salt

 

[Capn-Crunch]

Do a folliar spray, then add Mg to your water

 

[Timtam420]

Add how much?

 

[Capn-Crunch]

I use 1 tsp per gallon for a foliaer feed and to water as well.

Adding Dolomite will up your PH...so unless your PH is low, I'd avoid the Dolomite. Plus, it will take awhile to become available to the roots. I'd foliar with epsom salt simply because your leaves don't look Ca deficienct, just Mg.

Spray just once or for the reminder of the grow? Can you topdress with Epsom salt?

 

[Purpsmagurps]

thats not MG thats potassium deficient

 

[Purpsmagurps]

if it were an MG problem he would have run into it by now, your problem is with ph locking out potassium, too much of another nutrient locking it out or not enough if it.

 

[Purpsmagurps]

mg yellows just in between the veins like little bars,

potassium hits the outer edge.

you are retarded. you dont foliar in flower. and any more nitrogen and these things will taste like shit in the finished product! and before you say MG isnt nitrogen you know what i mean.

What would you recommend I do?

 

[Purpsmagurps]

and im just talking about the last plant, the earlier pics WERE mg but they were fixed a long time ago. your plants want potassium, go get some terpinator. I loved the way that shit made my bud taste in the end.

ALL of those pictures were taken at the same time - yesterday

 

[Purpsmagurps]

well the MG deficiency has stopped and is no longer affecting the plant. the look of the chlorosis is long decayed and not yellow, if it were yellow it would be a new deficiency, im looking aty what is yellow now and its potassium the plant in the last picture is lacking, the first ones are fine now.

 

[Purpsmagurps]

your curling down though means that they have too much nitrogen in them so more MG would fuck em up bad. plants use potassium to fatten and sweeten the buds, which is the phase you are in now.

Now I'm more confused than I was when I started this thread. Honestly not sure how to proceed...
