and your ph. I use botanicare products and use CalMag all the way through bloom. I know not everyone agrees with this.....but it certainly seems to work well for me.

good luck.

Ok so I added Cal-mag to my rez and it did not help things. I may have a bit of nute burn going on now cause the cal mag raised my ppm by 200 to 1400. Now my plants really look like chit.:yoinks: So my question is, all my plants are in a soil bed a few look ok and a few look bad. I have decided to flush water with plain tap water (450ppm out of the tap) for about 3 days and see if this helps. I ordered a R/O filter today, so as of Tuesday I will be using only RO water from now on:woohoo: Do you think that what Im doing is a right? Please let me know as Im trying to save this crop. Will flushing with tap water thats 450ppm help? They are at 35days flower today....and look like there at about day 21

almost positive that is a magnesium defficiency. 1 ounce epsom salt to gallon of water. suprised calmag did not help. the next time you run that ffof i'd put a bit of epsom salt in the soil to begin with.
 
If the cal/mg is locked up cause of the h2o source adding more cal/mg will only increase the problem. First flush like suggested, then you can correct the problem. Smoke:joint:

the ph is too high and causing the cal mag lockout.

the correct prosedure is not to add more calmag but to regain control of your ph which should be 5,6-5,9 if hydro and 6,1-6,4 for soilgrows.

the absolute worst thing you can do if you have a lockout due to ph is to add more nutes to the mix. it just leaves more unabsorbed nutes in the medium which will fuck with your ph.

ill tell you right now that every single full nute product on the market has a sufficient level of mag and cal to avoid such a deficiency as shown on that pic. the problem is not lack of mag in your nutes, but the fact that a cannabis plant cannot absorb mag in ph's below 5,5 and above 6,5 so it is vital to stay within this window.

you should NOT be adding a single component nute to your feeding schedule unless you are professional. and forgive me, but i think you are not. stick to the regular full nute products and boosters and be very attentive with the ph. ph - ph - ph is what i tell everyone i teach how to grow, ph is the key to a successful grow trust me!

i can tell by the curled tips on that leaf that the ph is too high. do you water with tap water straight from the tap? if so, that water has a ph of 7,0 which is too high and will cause lockouts! you will see that the leaves bend downwards at the tips like a claw.

the symptoms are lack of magnesium, but the problem is the ph. thats the effect and the cause. i swear 90% of the problems in the infirmary is due to people watering with straight tap water ph 7,0 and getting mag lockouts!

tsk tsk.. details, details!

if im wrong, click my sig and come yell at me in my threads or groups hehe.

Well I adjust my Ph with a digital meter every time I feed. From what I understood the PH for soil is suppose to be 6.5 and mine is spot on each time.....

Hi max...Artic is spot on with the r/o advice...AT 450 OUTA THE TAP..only bad things are gona happen...flushing with TAP will take you the wrong way.. Most high quality nutes are formulated for r/o...Some "HOUSE" brands are formulated for local water supplies..and even then water supply systems/delivery have different residual build-up over years of use...so the problem only intensifies.... you will be amazed at how well they will do if you feed them "pure solutions"..ie: r/o-full strength nutes...now by full strenght i mean..according to directions from manufacture...in doing so...you are achieving the "CORRECT RATIO" intended when they whip it up in the lab... You can delute to the PPM range your plants are comfortable with according to ..AGE..HEALTH..WATTAGE.. CO2..GROWING STYLE..etc.etc.....Its kinda like this..You dont go to the local pub and ask for filtered toilet water,do you...Why give it to your plants...R/o's the way to go...Hope this helps..You & your plants...rs,,,

Make sure you check your ppm/ec after adding Cal-Mag as i think this will raise your ppm/ec. Just keep a close eye on this.
Did you miss this post? It was posted on March 7th. Might have saved you some trouble IMO.

Yeah Who, I did see your post and the cal mag raised my ppm by 200 I thought they could handle it with Co2 and all. Not a good move on my part, good information on yours tho, thanks. I can't wait to get this RO deal going, should be here Mon or Tues. I hope this helps.

How much CalMag per gallon raised your ppm 200 points? And you foliar fed them CalMag too? Ouch.

then i suggest the following actions.

1. doubblecheck that your digital ph-meter is calibrated correctly and measures right.

2. measure the runoff water coming out of the pots. 6,5 is still a tad too high, 6,2-3 is better. if you are just a smidge over 6,5 you might get these lockouts.

im quite sure that this is merely a ph issue.

Maxyyeild man, i hope you get it all figured out, call on a ganja god or goddess for help, just talk to your plants out loud and they will answer you. This might sound crazy but it really isnt. Have a pos and productive day all

I also believe this to be pH related. His Medium is FFOF and is always low in Lime so you don't have any buffering going on.The run off should not be lower then 6.3 and not higher then 7. Check the PH of run off. Lets us know what it is

I am no expert, so take info I give for what its worth. Sometimes its as easy as adjusting your PH a few points. I had some orange spotting do to ozone generator (very small spots and lots of them) as well I've had what looks more like your problem because of cal deficiency, Fixed it with cal-mag @ 1/2 strength in rez. If cal-mag works great, but before continuing it educate yourself, there should be plenty cal in lucas. One thing you need to consider, is your tap water, and why it sometimes can cause lockout, check out this link http://www.urbangardenmagazine.com/index.php?id=190 If your short on cash check out this link http://www.icmag.com/ic/showthread.php?t=55810 It's not a perfect fix, I hope they help.
