Week 10 | Day 68

3gal fabric pots
Medium
40% vermiculite, sphagnum moss, coco pith​
20% perlite​
40% Epsom organic, reused and cooked 3 weeks prior to planting with 1/3rd dose Epsoma Starter Plus dry amendment(5-3-3), good for 4 weeks bag says.​
Supplemental Nutes
Fish Fert, veg (5-1-1)​
FF Big Bloom, veg+flower(0-0.5-0.7), plus 0.1 Iron, microbe food​
FF Tiger Bloom, flower (2-8-4), which has minor amounts of all other important nutes: mag, boron, copper, iron, manganese, zinc​
1% Milk - I consider this my alkaline Big Bloom, its has food for microbes, plus a little bit of every nutrient.​
Grandma's Molasses - for the flower stage wk4-5+​
Pure Epsom Salts - Mag & Sulphur​
Tums - Calcium​
​
Situation
So I've been doing pretty good on my 3rd grow ever. BUT here I am about 3-4 weeks out from harvest for my auto(on right in pics) and she's starting to have fan leaf symptoms. First was 4 weeks ago, where new growth was very thin leaves and more light green/yellow than my usual solid green new growth; typical symptoms of PK excess. Anyways I didn't notice much stunting in growth because everyday I could see growth even if it was just sugar leaves looked bigger. Anyways after that I did 2 waterings where 30% of volume was milk - helps me fight acidity lock in soil...I believe lol. Then I did one watering with 1.5tbsp/gal pure epsom salts, because I saw fading interveinal green on 1 or 2 of the lower fan leaves on the auto. That was 2 weeks ago, haven't seen any interveinal chlorosis since. About week n half after that, 3 days ago after my normal feeding of Tiger Bloom 1.5tsp/gal with 1tsp/gal Big bloom, I noticed 2 or 3 orange/rusty spots on the fan leaves. "Uh-Oh, calcium deficiency" I thought. Which I believe I'm correct, but I know excess PK can cause mag/cal lockout...but the interveinal chlorosis hasn't progressed any so maybe its not that and just a plain by itself, cal deficiency. So this morning I crushed up 3 tums with only Calcium Carbonate 1000mg/ea, sprinkled them as a top dressing, and watered 1/2 gal w/molasses+1/2 dose Tiger bloom(1.5tsp/gal, bottle says 2-3). I think I'm 3-4 weeks out from chop day for the auto, so I really hope to see these calyx's swell some more.​

Being the OCD, maryjane loving fool I am, I believe I've thought of everything lol, but I wanted to throw it up here for any and all opinions. For learning and yield haha​

You’re adding wayyyy too much stuff and probably in the ring proportions I’m guessing. Tums?

Looks like a calcium lockout from unbalanced nutes.. Probably too much mag..
Definitely not a deficiency with all you're feeding..

Sorry, I think I need to correct a misunderstanding . If you think I'm feeding all those Supplemental Nutes I listed every feeding that's incorrect. That's why I specified just veg, or both, or flower. It more a list of what all I have used throughout the grow, I've only fed epsom salts once 2 weeks ago. I've only fed it tums as a surface dressing earlier today, etc.

Ring proportions?? No and my feeding is like this: water, feed tiger bloom and some big bloom, water, just tiger bloom, water, saw mag deficiency so epsom+water feed. And I pour it into a red cup, which I pour 2 or 3 - wait 15 min or so, pour again. Its never been all that stuff at one time....that's why I specified what I used when. :-?

Buy a complete plant food, Fox Farm is not very complete if you're not using ALL of their products. You've added to much Magnesium compared to Calcium and that will cause deficiencies. Traditional A+B formulas contains enough Calcium and Magnesium in the right ratios.

Milk and molasses probably do more harm than good since you're growing with mineral salts in readily available form. Molasses is known to crash pH if overused and adding straight milk sounds like a unpredictable practice.

Steer away from companies asking for more than 3 different products in their base formula.

Cheers!

Thank you. Yeah my next run I'll need to get a whole kit. I just operate on a stupid tight budget, and bought those fertilizers as I saw them. In regards to milk, I've read too many positive stories using it as an organic pH up, plus it has a tiny bit of everything in it; also used in a 1:3 or 1:4 ratio with water. Granted I thought FF tiger bloom was organic bc FF Big Bloom is. So that will change also bc I want an organic grow. Let the microbes work for me.

pH crash from molasses huh? I'll have to read up on it again. Grandma's molasses pH is stated to be around 5.4 which isn't too low. I use it more from a bro science perspective during flower. Heard the microbes love it. Maybe once every 2 weeks I might put 1tbsp in a gallon of water.

Good looking plants thus far, I say pluck the leaves and watch the new growth.
In regards to nutrients, I recommend keeping it simple and sticking to a proven and reliable brand/schedule
GH Maxi series or Flora series.. head or lucas formula OR 1/2 strength from the label w/ calmag, silica... thats it
or if money isn't an issue go with canna ab or something simple of the likes. no need for 20 bottles.. no need for complicated breakdowns on micro/macro nutrients.
The plants will tell you what they want and when they want it, especially in coco.

Idk if those are organic or synthetic, but I got a sweet spot for organic(or a mental issue :D). But yeah that's my plan growmies, get a source/system of organic nutes for whole grow.

Thank you for the compliment on the girls! Only my 3rd grow ever, but I've read like crazy over the last 5 years and stay active in the forums. Always something to learn...like FF Big Bloom is the only organic nutes bottle from Fox Farms lol. Im gonna check them when I get home in a couple hours and share.

Well I didn't grab a pic, but I didn't see the issue worsening. Also, I didn't know this but molasses has some calcium and stuff in it too. But they're doing well. Thanks everyone
