2 years 3 nute programs same problem week 4

[pip313]

I start out in flower with nice green plants. At week 4 my plants yellow hard every time. I grow dwc trees and small plants. I started with GH 3 part and switched to lucas formula before ending with maxibloom. Ph 5.2 to 6.2 and 5.8 to 6.2 neither made a difference. Ec 1.8 to 2.0


Leaf showing moderate defeciency at week 5



Plant at a week or two

I have a idea what it is but I want unbiased opinions.

I used to think it was a ph issue as i did not have a meter for a long time but the last 2 harvests proved it is not ph. I check ph daily and adjust only initially as ph doesnt rise too much before change out.

Change out is every 2 weeks with water and nute top offs to maintain ec of at least 1.6.

Is it nitrogen? Im scared to add too much in flower as thats usually considered bad.

Check your root zone for intruders. Don't mean to alarm you but sometimes continuous problems garden after garden can mean root aphids. Have you seen any flying insects?

Edit: I forgot to add that people with RAs have successful veg cycles, only to be followed by phantom deficiencies/lockout/imbalance problems around the 4th-5th week of flower. If you can rule out pests, start thinking water supply or something that could cause off gassing. Its a very slim chance you've had the same exact problems for 2 years and it actually being a nute issue of ant sort. Good luck man.

I just started ewc tea but I havent had bacteria or bugs.

This plant is a huge yeilder, last tree was 4 feet high 5 feet wide yellower than shit and just as fluffy. Took at 8 weeks not 10 and still got 1.5lbs.

What nutrient would it be assuming it is a nutrient based off the pic of the leaf? It is possible it is just a heavy feeder. All my plants start to yellow at week 5 but this one is a 10 weeker not a 8 weeker so any yellowing at week 4 is too soon. She really starts to bulk weeks 4 and 5 then she slows obviously due to chlorophyll loss whatever the cause.

Shes greened up a bit the last 24hrs but i hit her hard with nitric acid and epsom salts I figured it was nitrogen or magnesium based on how its yellowing but i dont know which is fixing it.

At an expected yield of 2lbs I cant afford to guess. This plant is literally 90% of my next 3 months income.

To me it looks like one of those problems that says "lock out" and no specific textbook deficiency, and could be a combination of elements unavailable to the plant. Whatever the reason be, not necessarily pH, but SOME issue with the root zone, and inability for nutrient uptake of some kind. You say they greened up a bit after a shot of Epsom, how do they respond to CalMag?

Do you have nice white healthy roots? Have you 100% positively ruled out pests? Im not sure that broad mites cause the same phantom deficiencies after a healthy veg cycle, but they are microscopic and can go visually unnoticed. How is your water supply? And have you grown this strain before with the same setup/nute schedule/etc?

I'm not a hydro expert any means, you're going to want another opinion just because of that. But I can tell you I would not be giving them any N.

I just wanted to give my two pennies due to the fact you've had reoccurring problems that sound very consistent. A lot of opinions are going to vote for either pests or some unconventional underlying issue.

I feel you on the stress of keeping your ladies healthy for those reasons, hope you get it all figured out.

Edit: Honestly I hope the problem is simple and easy, I don't mean to complicate things!

 

[pip313]

Roots are healthy, i just doube checked no bugs even very tiny ones. My water has good amounts of ca and mg so I dont use calmag. Ive ran this strain with a buddy for years we both used calmag at the begining he still does. I find calmag to raise ph too much and the amount of ph down needed raises ppm to much.

Trust me I dont want to add nitrogen but the fact that nitric acid did not cause fert burn concerns me as it should have burnt some tips.

She got mycorizea fungi for the first time this week maybe thats whats helping.

2 new air stones in the bucket and the pump's right around 2 watts per gallon for the total system.

Foliar with Iron in veg and first 2 weeks of flower we buy powder form and a bag last years.. Also foliar with OG Bio War tea will help but the iron will have your plants happy and green. I have seen this many a times and once we foliar with Iron its gone.. JACK

 

[pip313]

Iron? Never entered my mind ill research it some thanks.

Edit my symptoms dont really say iron. I guess its mg. Ill just cobtinue to add mg and nitric acid in reasonable amounts until its green. Thanks for talking it through with me.

I said the same thing then I foliar with Iron and bam... The tea with iron will have your plants shiney and green.. But what do I know not like I grow I just come on here to give bad advice...

 

[pip313]

Ill give it a try it cant hurt. Iron is supposed to affect young growth first, young growth is the only not affected.

The bulbs make it look even more orange than it is but here is a pic. Or two.

 

[Green81]

I would listen to Jack, he's got the canna world lapping up his grows and for good reason.

[nkatadelgormo]

If your going to listen to anybody on icmag, it would be jack. Keep your ears open and listen!

 

[pip313]

So the myco fungi caused the greening in the last 24hrs? Cool them bastards were worth the money then.

It sucks i gave myco fungi ben. bacteria nitrogen and mag at the same time. Its greening up but what caused it? If jacks right and its iron its gotta be the biologicals.

 

[pip313]

What kind of iron supplement do you use?

Would a chronic iron problem sound possible? Like 2 years chronic?

 

[LEDNewbie]

You mix the iron with your tea jack?

 

[nkatadelgormo]

More than likely your water source. If you've changed everything else that would be my guess. Mycorrhiza in my opinion is always helpful. With that being said, try the foliar jack suggested.

 

[pip313]

Water source is city of detroit, very good great lakes water.

K. 1.2mg/l
Sio2 23.4mg/l
Mg 8.33mg/l
Ca 29.7mg/l
Na 8.52mg/l
So4 31.2 mg/l
Cl. 9.5mg/l
Bicarb 76mg/l

 

[LEDNewbie]

Just do what jack says. Man knows his shit.....

 

[pip313]

Jack wants me to spray iron on my plants. Folier spray of iron isnt supposed to be absorbed well and after asking for a recommendation on brand he had stayed silent.

Iron affects young leaves first,my young ones are fine.
Iron starts from the top down my plant yellows from the bottom up.
Iron starts at the pitol and goes to the tip mine is reverse.
Im on week 5 and im supposed to spray iron on my plant? No fucking way in hell when the suggestion doesnt come with any reason besides trust me. If I was in veg id do it no question but I have decent sized nugs and im not spraying shit period.

Maybe if i showed more than 1 symptom or had a better reason than trust me because ive been through it but im not telling important stuff like what form of iron is best. Or more importantly how 1 symptom shared with 2 or 3 defeciencys is for sure iron.

Im not tryin to be rude because help is apreciated but we are not talkiing about adding somthing to my rez we are talking about spraying iron on 5 week old buds.
