Second Opinion....

Mojave...

I take back what I said, I believe I have mistakenly taken you out of context, thats my bad.

here's what I have so far....

4 litres each salts on thursday.....

friday I mixed up 2 litres each grow / bloom with salts and molasses.

(4ml bloom / 4ml grow / tspn molasses / tspn salts / 6 litres water)

today I gave them a lil bit more salts (just 2 litres between them)

the yellowing seems to have ceased and the spotting hasn't gotten any worse at the moment, so I'm hoping it was a lack of mag all along and a little bit of underfeeding due to being too cautious with my nutes, they are looking a little greener today, still some lighter new growth but I'm hoping that will start to balance itself out now.

(i'm hoping that the problem was that they started to use up the reserves to start flowering as I wasn't giving them enough in the soil.

worst case scenario I'm gonna need to flush the pots and start again.

also had the heating on in my house last night as it's getting colder here and I'm wondering if cold soil (overnight lights off) had anything to do with the nute uptake being low

I'll wait til monday/ tuesday now and give them nutes again minus the mag and see how I go from there.

Again cheers for your help guys, it's appreciated, I'll keep you all posted.


***just want to note - I don't usually water that much, it's just that I figured giving them a good dosing over a short period would iron out the problem quicker***

Why are you using salts? That could be what is causing the problem. There is plenty if sodium in regular water, nutrients and soil. I can understand the molassas.
I am not a soil grower so I dont know what the "salts" even are.
I grow hydroponics with hydroton and there is no nutrients in the media at all. Soil retains nutrients/salts so it is easy to get a buildup to a point of toxicity. Even if you flush with fresh water for two weeks it would not hurt your plants. Point is it cant hurt to flush your plants with fresh water for a few days, then start your feeding program at lower amount of nutrients. Follow the directions of your product at half the max strength. I never go full strength. Maybe ditch the salts unless there is something about these salts that I dont know.

Best bet when you have any nutrient issues is to flush with with fresh water for several days then start your feeding over again. If you want to solve the problem faster then flush with a final flush product to release the nutrient bond between the plant and soil. I use general hydroponics Flora Kleen but there others out there. I use all general hydroponics products and humbolt myco madness.

With that said its trial and error for everybody starting out. You have to figure out what works best for you.
Golden nutrient rule to follow. If you see a problem developing flush with fresh and start over
Good luck and no worries.

I cant comment on the nutes as not what I use but Im guessing salts is epsom salts - not salt salts.

 

[evln00b]

yeah mate epsom salts... and they didn't cause the problem because I didn't use them until after I noticed this happening.

Anyhoo, I did say I was going tto wait, but I decided against it... like mojave said, flushing them won't hurt them and if it is lockout then it will help, so I've just flushed em out.

I've got a couple of better pics here I'll put them up in just a sec.

 

[evln00b]

OK here's the better pics... I've flushed now etc so I'm hoping this will improve, but still would appreciate any opinions on this
**it may help someone looking in future**

Plus I'd like to know exactly what the problem was myself so I can deal with it in the future if it happens again.

Mr.Evln00b..
Now that I can see the pictures even better than I could before,, Im going to say that it IS a pH problem.. And Im sure that when you get to check your base water pH,, Nutrient pH,, and finally Run-Off pH,, theyre going to be CLOSE to out of acceptable range.. Maybe even actually out of acceptable range.. Id also like to say that it looks like things are just starting to be close to unacceptable,, so the damage isnt too bad.. But if left,, things will continue to progress in the wrong direction.. ..

Much Love and Respect to you and yours,, Sir.. ..

couldn't get a ph pen, didn't wanna buy a crap one and the others were just too pricey for this time of year lol.

so I did a lot of reading and found that you can use dolomite lime as a PH balancer / buffer...

further reading showed that dolomite lime was just calcium + magnesium ( so basically calmag rite )

I'm an avid rep keeper also so I had some pure calcium dust lying around and I gave them a dose of that along with more epsom salts ... been giving them 4ml bloom + 4 ml grow in 2ltrs water, seems to have helped...

One of them is still looking a little less green than I would like, but they seem to be doing a little better now like I say... I'll keep you posted !.

**for the record i gave 1/4 tspn calcium + 1/2 tspn salts in 2ltrs water along with the feed**

I think PH was a slight issue with them but ultimately it was cautios n00bie underfeeding that caused the majority of the problem

HI

I think that it is a PH soil problem..... Ur plants roots cannot anymore take nutriencents from the soil, this is why they are turning yellowih, purple stems,due to not enough nitrogen in the plants and getting some coffe brown points due to deficiencies....

Just try the following:

Place ur plant into ur bath tub,open ur faucet, had water to the container, till the water falling done from the base, ....wait like 20 / 30 seconds without turning off the faucet.....and then place a glass under your container base and get back in it some water from ur container.

ANd now test Ph from this water....if the ph is higher than 6.8 ur getting an acid soil, due to over fertelizing are bad ph control, the same if ur ph is under 5.8!!!

If its the case, let flush ur soil with water till ur getting back the real ph 6.2/6.5...

i had the same problem crop up on first one plant, then a bunch of them. i think it's a combination of problems, mainly cal/mag like you said, possibly pH issues, and possibly from the plant being rootbound. i foliar fed my plants cal/mag and that almost stopped the plants from turning more leaves like that, hence why i think it isn't JUST cal/mag. I'm using 2 gallon pots, so the plants must get rootbound relatively quickly which may have contributed. also fyi my soil's pH is between 6.2 and 6.4.
