Help..Yellowing I can't fix(pics)

Someone help please!

O.k,Myplants are in a premium potting mix(Debco pot and tub) with a bit of added perliteworm castings and a small amount of dolomite lime.The soil contains slow release fertilizer.Pots on my larger plants are about 18inx18in and the Ph is about 6.5...I have to rely on a powder test kit so its not very accurate.
I used seaweed extract during veg and now thrive fruit and flower(15/4/26) at 1/2 strength every 5 days...i know it's not the best fert but it's the only thing I could get locally for flowering.I water once a day with regular tapwater and they sometimes get a soaking from rain.

The problem with the plants is yellowing and dying leaves,It starts on the oldest leaves and slowly works its way up.It begins as a sort of slow fading from lime green to yellow with whitish patchs and sometimes dead patches starting at the tips....Not like nute burnt tips though. I had this same problem(i think it's the same thing) during veg,I re-potted and the plants and they were fine.

here are some photo's
This is the beginning of the fading


to this



and eventually this



Full plant pics








This plant had the same problem at the beginning of flowering,I repotted and now it hasn't got a yellow leaf on it.Too bad it's my worst strain.




The only things I can tyhink of are Magnesium(I used Dolomite lime though) Nitrogen deficiency(I thought the ferts would fix this!??!) or rootbound,but I don't think the pot on the larger plants is small enough tocause problems and the smaller plant(ak48) I believe should be fine in that pot....If I cant fix this in the next few days I think I'm just going to re-pot and risk hermies

HELP!! :bashhead:


At the beginning of the problems

I'm having the same problem, looks like magnesium deficiency to me. I don't know, but I think over-watering causes it, also it might happen if your soil or pot doesn't drain well, or if you added something that depleted the magnesium, or if it has a ph lockout. Good luck with that.

I think they could of used more N, the green on your healthy leaves isn't very dark. You're outside they may need a larger dosage.

Needs more nitrogen in the plants diet :) I would get a better nutrient, the one you are using is not balanced and can cause nutrient problem absorbtion if the plants don't have the proper balance.

Get something with 20 npk or les anything else is a waste.

Make sure what ever one you get from the hardware store, never use anymore than 1/2 teaspoon per gallon. If they are over 4 feet tall, 1 tsp per gallon.

Thanks everyone :smoke:
If this fixes my plants I'd be happy to pay;)

Is there any Particular fert I should buy?Can I use dilluted hydro nutes?Thats the one thing I can have fairly easy access to without taking a 500km trip.

Cheers

like sativo said, make sure you're not over watering. I'm dealing with over watering recovery and my plants displayed the same type of yellowing and brown spots.

Yes, you can use hydro nutrients, but if the nutrients says for hydro only, get a different fert, each one is formulated if it states used for soil only or hydro only.

What do you have access too? hydro shop or a garden shop?
 
Once again....Thanks peoples.....Fkn champions :headbange

I have Canna Vege and Flora....I will be setting up a 8plant/2 rez DWC(4xSensiStar2xWonderDiesel2xLemonStinky) next....Yeah,I know I have the wrong nutes but I was hoping I could use em' for my outdoor stash at least....i.e ...only stash!!!

Stitch,I don't have access to either but I need to take a journey to the city(500km) for my DWC setup so I kinda have access to anything in the next few days..
Cheers

Thanks :wave:
 
Master shake.....I thought it was Overwatering too for a brief time but everytime I have chilled on the amount of water for a day or two it has accelerated the bad shit....Fkn Nitrogen...and I thought I grew the "shit"...I missed the basics!
I am forever humbled....Cheers!

You using just canna vega flora? If so that is not the one you need a grow fert to stop the yellowing, bloom ferts if it has good Nitrogen it will work.

You don't have to use hydro nutrients, you can use store bought stuff till you get them. Just do not listen to the directions on the back of the bottle thats for sure.
Otherwise they go from yellow to brown from burning :)
