Calcium deficancy? Soil ph too low to absorb Cal Mag?? HELP!!

Hmmm I'm almost certain tap water isn't a chemical and foliar feeding is the fastest way to correct a Cal/mag issue. Also calcium and phosphorus in high concentrations form calcium phosphate locking out phosphorus.which is what would happen due to n toxicity locking out calcium from heavy feeding... but what do I know, what with all the exclamation marks and everything you must be an expert

Ok...one LAST question...what about watering with dolomite lime?

They usually don't come back after Googling and realizing I was right. If they do its certainly not to be informative...I would suggest foliar feeding calmag when the lights go off or under low lighting while watering with plain water, next watering if you see improvement you can go back to your regular schedule but feed half what you are now. Phosphorus also gets locked out with excess moisture so if you've been flushing, careful

i don't google as u do! i experience my shit. i have been growing long enough to deal with most common problems a grower might face, indoor and outdoor, different mediums! so u can stuck on reading a bunch of bullshit in untrusted websites and advice people something u never experienced! cannabis plants outdoors never get foliar feeding only rain! WATER... and all nutes intake are done at the root zone. u can pretend that you know better then me but not Mother Nature. plus ur not giving him any ratios... anyways, hope he'll try ur way and burn his leaves and give us feedback.

Thats what I am seeing also. Overfed from flushing MG soil. Then pumping them full of CalMag and other nutes on top of that. Just plain water for a few weeks. And pH up/down will do nothing to alter your mediums pH. That stuff is for the hydro growers.

Actually, I flushed the girls I was having issues with using plain pH'd water. The problem looks like it MAY be getting better. I'm constantly chasing my pH because this MG soil with its 6 months of time released nutes!! I'll NEVER make that mistake again. I know MG is the issue because one of my girls didnt look so impressive from the jump and i pretty much wrote her off. I moved her to a different area to veg and paid no attention to her, no nutes just water. When I changed lights to 12/12 I threw her in the box with the others just for the hell of it. She is the healthiest Ive got and is producing the best, although not anything fantastic. This is pretty strong evidence, to me anyway. I'm going to play it safe and give very low nutes to finish them out. I'm terrified to spray ANYTHING on them because I've got buds all over the place.

I only use the pH up/down to adjust what I'm putting IN..I wouldn't dare try and use it to adjust my soil. I'm new but not stupid lol!!
Ive given the girls a good flush and plan to push them GENTLY through the remainder of their flowering! Taking what I've learned this go around and shooting for fewer mistakes on second grow which I plan to start by weeks end

Looks like nute burn or a deficiency ... blackstrap is something some growers give their plants a few weeks before harvest... not required though
You may want to increase the amount of calmag.. 1 tablespoon sounds right

Not to be rude or anything, but are these test's deem'd false than? http://en.wikipedia.org/wiki/Foliar_feeding
Flush your soil with high PH'd water, then get it to stabilize. Once that is done, continue watering with plain PH'd water. From there you can judge if it's too much or too little mg-Cal

Like qwizoking stated, you need to flush your medium because you have an escess in N causing it to lockout P and Mag. GanjaHome sorry to say bub but your "experience" has been skewed in some way, obviously you haven't read up much on over fertilizations causing lockouts or you wouldn't be sticking your foot in your mouth by saying qwizokong is wrong because he/she isn't wrong, in fact that was the exact thing that came to my head as soon as I saw the pic's. I just dealt with this myself. In veg you cant see the P def because the plant isn't using much of it but by the time your stretch is over in flower your leaves start getting little brown spots, then the yellowing, and finally necrosis.

I did the flush, but CANNOT stabilize it. This soil has 6 month time release and the shit will be harvested, dried, cured and probably smoked before it stops releasing nutes!! I'm just gonna try to baby these girls through to the end...Every single problem Ive had in this first grow stems back to my soil!! Should have done my homework first!!

In his defense...I gotta say...what I got from his advise was to flush, because of lockout from nutes. He just said not to use cal mag as foliar spray...

your soil is fine melissa.
get the same soil next time and just give her ph'd water for the 6 months the bag says.
your problem was that you added nutes when there was no need to add nutes.
i use mg soil and nutes and my babies are great.
dont blame the product, if you had followed instruction then you woulda been ok.
good learning experience though!!

Yes, I'm so VERY aware that adding nutes to the already fertilized soil is what caused my issues. But I gotta ask, how long do you keep your ladies in the pot? I started my girls mid April and expect them to finish by late August or September. By my calculations that's only about 4 1/2 months...and the amount of nitrogen being released is extremely high for veg and most def for flowering. I'm also wondering about the low Cal and Mag amounts. How do you get around that?your soil is fine melissa.

are you talking about the bag nutes?
all i did was put my seed in soil, let it grow, give it plain water until the bottom leaves start to yellow then i start with light nutes.
i had no problems.
??
for my food it has all the plant needs except the molybdenum (Mo)
next time try cactus soil and dont feed until you see yellow leaves
just ignore the bag and feed when yellowing lol
im using "plant-prod ultimate all purpose plant food 20-20-20"
but am switching to miracle grow bloom booster for 12\12 -15-30-15
i add a tspoon of epsom salt to my water for watering and that gives it magnesium
with the calmag just do a little tiny bit at first
i dont have experience with calmag so i cant really speak
your lucky you made mistakes cause you learn from them, so next time you grow you will know what not to do
also my plants sprouted june 10th&13th
took about two weeks before i was feeding them
good luck!!

Equal parts perlite and dirt will cut your nute concentration, I prefer to only foliar feed calmag. Mg bloom booster has all the nutes except mag Cal and sulphur, (including mo). The African violet soil has small amounts of dolomite lime but a lot of n, I would transplant into AV mg, to start equal parts perlite and seed starting mix or the organic. Both have low nute levels and don't have the time release balls.. foliar feeding is the fastest way to correct a deficiency, I foliar feed calmag nightly, when foliar feeding a light mist is what you want with room temp water, if it beads you've sprayed too much.if you spray too much or dry to fast it will leave hard water deposits on your bud, if that happens no worries as the plant transpires naturally it will get absorbed eventually...I wouldn't foliar feed once you start flushing if you do that or just stop a week or so before harvest

I'm talking about the MG soil...it has time released nutes, combined with the all purpose MG nutes...THAT is what started my problems. I've certainly learned a few lessons on this first grow...but it's very enjoyable none the lessare you talking about the bag nutes?
all i did was put my seed in soil, let it grow, give it plain water until the bottom leaves start to yellow then i start with light nutes.

HA!! This is a learning experience....and so far I have learned NOT to grow in MG soil with time released nutes and feed nutes on top of that. I do believe that YOU, yourself suggested that I was overfeeding
