Spotting on Fan leafs...

[~Dankster~420]

Yeah bro.. you got a case of cal defiency! I had the same colored spotting on a few of my plants. Mine seemed to just be towards the "bottoms" though. I 1st thought mites also! "Being they " "spots" showing up on bottom leaves! But after careful inspection, it was cal-mag 4 sure!! So, I took alittle epsom salts & also sensi-cal bloom & it fixed my girls right up.. there all happy again! Yayyyy.. I sure hope you get the problem fixed. I hate it when one of my girls are under the weather! Hate it!! It pisses me off!! Well anyway, take er easy bro.. later.

Hi......welcome to this forum i'll suggests you to go with the experts views.

Been growing for 11+ years. But in NO WAY shape or form consider myself an expert! I find myself learning new grow techniques everyday. And even though I've been growing 11 years, I've not had 2 battle "all" of the defiency problems out there, or disease's either. Its great 2 know that where I haven't delt with it all, to know that there may be some fellow growers out there that has, & will lend a helping hand. And same goes 4 me.
Cause Lord knows that I will have more problems i'd say down the road,lol.. Happy 420. Peace.

I'm 5 weeks into flowering, I noticed the same on my leaves...
p.h city water- 6.5
Roots Organic 707 soil
I mix: ( 1 gallon jug )
Soul synthetics - PeaK 0–12–7
Soul synthetics - Big Swell 2–5–3
Roots Organic - Buddha Bloom 0.5–2–1

Should I take a teaspoon of Epson salt with a gallon of water in try that, Or could it hurt the plants?
This didn't happen on my last grow, But I also thought at first it was because I was flowering them with t5's
and recently swapped them into my agromax 600watt hps tent set up. temp is about 75, good air flow.
Could them possibly being root bound cause this too?

thanks

Hey bro.. it wouldn't hurt 1 thing to add a "teaspoon" of epsom salts to your girls!
Hell, I added a tblspn! But I would start off slow, & if you see its correcting the issue, aadd another teaspoon to your gln of water, to make a full tablespoon. And also, I've known that once a plant becomes root bound, the tips of her leaves will look "burnt". And also, she will slow down in vegatation aswell! If there in flowering like I believe you stated, & they are root bound, I myself wouldn't disturb the roots. It may send the plant into shock! I mean it would catch back up eventually! I just wouldn't try it! But I guess, if you "had" to, & there wasn't NO other way round it, & your really carefull not to disturb the root ball during transplant, then go for it!! I've had to do it a few times. Just don't like to! I sure hope this helps bro.. I'm sure it will though.. take er easy.. Happy 420!!

Well we're getting close to harvest within 2 weeks for a couple of my girls a week or two more for the others. I'm letting them use up what's in their leaves...not dealing with the cal deficiency at this point.

However, it dawned on me the other day that MAYBE using the Britta filtered water is the wrong thing to do. I'm filtering out whatever is in our 'Great Lakes' hard water. Perhaps, I should just use straight tap water...ph'd of course. I know it has calcium in it because you can see it build up on faucets around the house (over time of course). It may be enough to prevent that from happening next time. A quick check with my cheapo TDS meter and I'm reading 150 ppm from the tap, so it's not particularly dirty.

BTW, I have done the epsom salts. It was right around the switch to 12/12. I think it was 1 or 2 tablespoons in a gallon of water. It didn't hurt. But that was two weeks before the spotting began. I considered crushing up an antacid tablet which had calcium AND mag in at about a 3 to 1 ratio into a gallon of water. But I couldn't find any advice for or against doing so other than a warning that there are other 'non active' chemicals in antacid tablets, like mint, that might not do well for the plants.
