12% calcium 2% magnesium 1% nitrogen.

Didn't want to use molasses constantly as can make medium all gooey.
 
Ok,good than.Just use that and hopefully it will take care of those rust spots.
 
Hi King'- I recall, you started Ca-Mg treatment a while back, right? Hmmm, those spots are not the typical looking Ca defc. type, but still could be--

... yours are larger, less stippled looking, but still have that brown edge surrounding the dead tissue,...(this is not Mg defc., BTW)... By any chance, did some water droplets get left on the leaves under the lights/Sun? Sometimes, burns caused by light lensing from the droplets can look like this too,... I do see some heat stress signs in the leaf shape as well... *** Sometimes, there's even significant differences in tolerance for physical and/or nutritional issues between the same strain-- pheno' variances, so to have one just fine, and another problematic is not unusual,... *** Ca is a poorly mobile nute', and it seems to start showing symptoms mid-to-upper levels of the plant, because Ca can't be readily stripped and moved from lower leaves, like Mg can,... fit's what you're seeing! Now, either what you're giving just isn't enough even though you're following directions, or there's a pH problem locking Ca out,... (case-in-point: I had a pair of MoB's, seed mates, and one went through nearly 4x the Ca input to stop defc. than the other had, which only showed the slightest sign..)... A soil pH would be very helpful, just to be sure, before I say to up the conc. of the supp's,.... Otherwise, the best thing to do is do foliar treatments; did we talk about this last time? ..you have two Ca-Mg supp's, Plant Magic and HN,... both are good in Ca-Mg conc.,.... Let us know about foliar treatments directions, and a whole plant pic would be helpful too,... a water spreader/wetting agent will be crucial for foliar spraying, do you have some of that around?
 
Hey waira, yeah that was on my last girls i pulled them tho due to personal issues :(. I have no idea if it is heat stress or cal-mag so sorting the heat problem out tomorrow so can cancel that out. I have someone else that water's my plants so its a possibility they could have spilt droplets on the top leaves but im sure the problem has progressed. I didn't think it was Ca either because starts from the bottom up and there is no damage at the bottom, saying that though i always have this same problem week 5/6 so meh. Thanks for clearing that up about the differences in tolerances as i couldn't understand why the other girl was fine if it was that issue because they get fed the same lol. Im pretty sure it isn't lockout as my soils self adjusting so i never have to worry about PH, but i will take a reading just to be sure. Although like i explained before because i use a chemical fert PM's Ca-Ma with my biobizz range it may be causing the nutes to be locked out, this is why i purchased the HN equilibrium which should do the job or am i fine using PM with my biobizz range? I should get this tomorrow and i will bump up the dose and see what happens. As for foliar treatment i dont have a water spreader/wetting agent. I will also get you a full plant pic tomorrow in natural light. Thanks for your help.
 
That looks like a magnesium deficiency
Sorry, not even close. If it were mag there would be a uniform light color between the veins and the vein would be still be a darker green. It would start near the leaf tips and work it's way back toward the stem.

I can't believe that no one has asked about your pH. What is the pH of both your feeds and your run off? I do see some calcium deficiency but also some P and K, suggesting it's nutrient lockout from the pH being off. Don't buy into the self pHing BS.

Also, please post a picture of the whole plant so we can see how the rest of it looks.

Well i thought with organics u didn't have to worry about the PH i will be getting plagron light mix next time as iv heard better things..
I havn't actually been testing my PH of my water nor my run off. I shall tomorrow though and post the readings.
I also thought it was P and K only because i laid off on the flower nutrients until week 5/6 where as normally i start feeding them at week 3, and P def causes the foliage to burn as far as i know.
Would you recommend me bumping up the Ca nutrients or do you believe its a PH problem? My other girl is fine too i have pictures but not in natural light only under HPS(which is no help). Thanks for stopping in muddy.

Also i been thinking of going for AN's Ph perfect range to solve most of my PH issues(if it is that lol).
 
I think it's a pH problem and would suggest you don't do anything until we see what your readings are. I don't subscribe to the thinking that pH isn't important when using organics. If seen too many growers try to get by without checking their pH, only to have issues.

Before you spend any money on AN pH Perfect check the pH and ppm of your source water first. For it to work properly the pH should be below 8 and the ppm between 100 - 125.
 
Thanks muddy I'll update with readings 2mo I don't have an E.C metre but Ph pen will have to do.
