Howdy.. Can anyone tell me what is causing this cal-mag type issue with the coloring of the leaves? I have gave supplemental calcium and magnesium and the issue looks to be leaning more towards the magnesium deficient side of things... Also I have noticed a few but not many at all of these "mutations" on the edges of the leaves as you can see in these photos. Kinda like the leaves have been torn. My room is 110% pest free, I had a spider mite issue a month and a half or so ago but I caught it early and check daily and have not seen anything since, nor any other type of pest or single insect either.

These clones were very starved back before they were transplanted into these current 5 gallon grow bags. I got them greened back up a bit and they were grow in fine and I decided to transplant. They still are growing "alright" but not as quickly as usual for me. The growth seems slower than usual.

I am growing in promix with added dolomite lime and added perlite. I have been checking pH and it comes out to around 6.0 to 6.3 every time which is actually great numbers for promix soil.

Using Advanced Nutrients Sensi A&B and supplementing with B52 and voodoo juice.

Any help would be greatly appreciated!

I would spray them with liquid karma or a fish additive like my favorite Organic gem. Theres other companies like Neptune.

I see burned tips from to much nutes, but I think its lacking N not cal/mag thats why I suggest spraying them.

I did give them a foilar feeding of Earth Juice Sea Blast "Grow". Theyvresponded rather quickly and did green up quiet a bit, this added along with the transplant from the 2 to 5 gallon containers.

Once the plants are nearing watering/feeding time again and issues have still not improved by that time, I will likely go ahead and flush them out with 1/2 strength nutes and a little added cal mag.

I honestly believe this is going to be my better choice of thought.

I am also going to increase humidity and temperature just a little and remove the fan from directly blowing onto the plants. By increasing humidity and temperature and correlating them correctly I will be on par with the VPD scale recommendations which is quiet accurate.

I plan to flower soon, I hate having to delay my plans but if correcting the issue gives more growth in return then I will proceed with leeching out some possible salt buildup, air pockets, dry spots, etc from the soil.

I will update.

Check the ppm of your pro mix fresh out of bag. Ive seen alot of promix that was made around July 2017 with crazy high ppm #s from im thinking a overload of lime they added.

Id recommend a quarter to half strength veg/nitrogen feed then next water a full strength veg feeding to fix issue.

Stop guessing what it is and buy a soil test kit.Make sure the NPK are all where they should be.That will solve 99 percent of your problems.You said the ph is right.

I run pH at 6.5-6.8 for promix.

They look like they are greening up. Should see growth speed up soon.

Thanks Lester, yeah she is all under control now and growing perfectly fine. Noticing slight twisting on the new leaves of some but no damages.

Thanks everybody!
