looks to me like a magnesium def too. cuz of the green veins but yellow leaf..
foliar feedin with a little epsom salts might help, if thats the prob.

hm definetly not a nitrogen def, they need no more nutes, they showed that having burned leaf tips
well maybe you overdid it with the Cal-Mag thing, if you'r using tap water then u bring a lot of cal and mg only by that. another source of Mg is Sweet which contains epsom salts
so, since Cal and Mg are often rivals so if for instance there's too much Cal, you will probably get a Mg def. symptoms since Cal blocks Mg
try applying epsom salts foliar as said and u'll c what happens, if it gets better i'd lay off the Cal part just a little in the future,specially if u use tap water
good luck!

Hi,
I'm new and learning so, hoping my questions are well placed.
Is the foliar application of epsom salts, in this case, to provide the magnesium? Or are the more reasons than this?
Does flowering have a tendency to change the ph of the grow medium?
What could be the actual cause of this mag def?
Thx,
sat

Id put like a tsp in a quart spraying bottle.. and ya adjust the ph accordingly.

USE THE SENSICAL INSTEAD!!
epsom will work im not trying to contradict anyone but the sensical is better and will address the calcium, zinc and iron aswell...
try not to water(foliar) the plant too much more i see thoes hairs packing on and dont want your baby to get mold/budrot
ive lost 1/2 pound on my last crop to that shit..

im not sure if the leaves will turn back green.. they might.
but id foliar feed once, then wait a day or so.. if your gonna see results you'll see it soon.
and they wont hurt your other plants.. make sure it isnt a big dose thou.
flushin your system might be somethin to think about too..just in case theres salt buildups or somethin

Yah I'm with the DigiHippy. I think you were just too lean on the SensiCal. 5ml/gal is pretty light and MJ loves cal and mag. Try 8ml/gal. The top should green up some after some treatment.
I feed my girls 2ml/L Cal Mag and that was just enough to stop a cal and mg def I had starting.
Foliar feeds should be 1/4 strength.
Remember, nutrient needs change as the plant goes through different phases and now it's bloom needs are increasing as it starts growing more bud. What was adequate cal and mag before is now not enough because of the plant's increased metabolism and growth phase. The more light,the more nutes. The hotter the temps, the less nutes. There is no "just follow this chart and all will be well". You have to modify the chart to fit in with your room, strains, lights, temps, nutes, etc.
Good luck.

you guys are all Clutch...thank u .....So boosting my PPMS up a with the Sensi Cal and Foliar will work? no need to Flush then yet? if i correct the problem...and even though my yellow leaves are done..will this diminish my yield or quality?
Foliar everyday until I see improvement or bump the SensiCal?

How are you growing? Hydro? Soil?
If you are in soil then 5.8 is too low. Mag gets locked out at 6.4 and lower.
First verify and correct your ph, if needed, before adding another drop of fert. Just give plain ph adjusted water for now until we get this figured out. This could be ph lockout, so I am taking back my earlier conclusion for now.
Once ph is verified correct, then we can look at if you are giving enough SensiCal.
New growth should be green and normal. Not sure about yellowed leaves but definitely look at the new growth for improvement.

N def starts at the bottom oldest leaves first.
This is mag def:
Oz definitely has magnesium deficiency. Oz's is just more advanced than this photo. These are straight from the guide sticky.
Oz's plants:
The bottom growth is nice and green.
Note the green veins on some leaves where the yellowing isn't as advanced. Sure sign of mag def. I can also see some cal def happening. Those brown spots on some lower leaves and brown edges are cal def. Usually see these two defs together.
You know what we're smoking.
