Hey guys no pics im currently not there.. but i have some major yellowing goin on 30-35 days into flower. First thought it was jus the strains cause i never did these ones before. Started off with jus 2 outa the 6. Now all 6 are yellow as f@** .. i did notice a few fungus gnats an put up stickys an sparyed with some gnat killer stuff. But still yellowing.. i jus recently hit em wit cal mag. Cause thought that could be it. Cause they went lil less then 3weeks wit non.. ill try an snap a pic next time im there.. but never had this issue before an almost every leaf is yellow now its insane .. so any info will help thanks in advance! !

You should really post up some pictures. I know its my first post on here but i myself am going through the same problems. Here are some threads you should check out.
If all your leaves are yellowing and dying out in that stage of flowering i would believe strongly that it is pythium.
Check your roots, are they all brown? They also give off a terrible odor.

I did actualy check my roots the bottoms were kinda brown but saw plenty new/white clean roots tho..but didnt check the smell them lol.. an im using a soil-less medium. Sunshine mix to be exact.. ima have to try an hit em with some h202. Or a root cleaner.. i did switch my nutes to roots organics but didnt have any issue with my last run... did reall good with it my last run actually..

An yes i kno. Pics help alott. I will soon as possible promis.

Id say nitrogen or sulfer.. but i know there getting nitrogen cause there plenty in the roots organics line up im using..but i dunno bout sulfer.. but didn't have this issue my last run using the same. Besides being outa of calmag for a cpl weeks.. but could the small gnat problem cause the yellowing? I have it bout gone now. But could of it caused it?

probably the lack of calmag tbh, either that or you havent been feeding them ENOUGH of their main nutes at a guess, hard to comment without pics

possible lock out. Too much cal will / can lock out everything.

if in soil. Brew a tea of alfalfa meal , kelp meal. Brew 1-2 days then add pureed aloe leaves and pro tekt .

then following watering do a compost tea.

if in hydro add more nutes. Make sure your npk is evenly balanced

Pics will fix the guess work. Along with your medium( soil or hydro). Nutrients or ammenents being used. Also did the yellowin start new the bottum of plant and work upwards. Orthe entire plant at same time. Or top down?? What your water source ?? This should help.

Im in a soiless medium. Sunshine mix.. an im using roots organics nutrients. An seemed to all happen at once. Water source is tap water.. an heres the pics.

Yes. Donyou know your base water ppm?? And donyou use a supliment camg product? Looks like mg def. and or ca. Epsom salts may work for you. To late for a foliar feed although. I would up your feeding. If not in dosages than in frequency. And use calmg in some form if not already

Also. You may be wanting to pick off discolored leves. Try not to. Even when you fix the def affected leaves will not go back to green. Just let the plant decide when to discard. Pulling leaves may spread the search for nutrients to other sugar leaves. But you buds look really nice. These hiccups happen. Nice job though!

I dont kno my base water ppm.
But Calmag was my 1st guess too.. cause i ran out n it started happening bout a week after went bout lil less then 3 weeks with out none due to me being busy an in an outa town(regardless my fault.) But thought itd be fine. But theyve had calmag the last two waters now.. an i use Botanicares Cal Mag Plus.

An another thing is there drinking alot slower.. use to water every 2 days .. now after 2 days there still heavy. takes bout 3-4 days for em to dry/lightin up. I usally run 2, 1000watts in my 4x8ft tent. But since i only have plants on one side im only running 1, 1000watt . So i kno thats how i got the gnats is from the pots stayin wet.. so ive lowered the cups i give em..
but yee ive never had this problem, tell now.

I was guna say it looks like they are already recovering. If there is nice green super trichomes growth around buds. It's usually a good sign. Hmm. And about your pots. Something isn't right if they are consuming less water farther along in flower. Donyou use the blue or yellow sunshine mix ? I would guess the yellow would e better for soiless. Higher levels of perlite. That being said. If you have gnats bad, the larva will be making a meal of your roots. In particular your rhizosphere. Not good.

Destroy those pesky fuckers. Bio warfare. ! Predatory Nematodes like to eat larva. Top dressing can help. I use a custom top dress to proactively hinder all bug reproduction.

2 qts coco coir
2 qts perlite.
2 tbsp diatomaceous earth
2 tbsp crab meal
2 tbsp neam meal

^ this layered over 1 inch of Ewc works well. But I'm in an organic living soil. Not sure the effectiveness in soiless

Nitrogen I recon. Gotta keep the N in your feed for the first few weeks of flowering

I thoughy the same but theres nitrogen in all my root organics bottles. An havnt had this problem since I switched to roots. But ill start to add more, i got some Aurora nitrogen stuff thats jus Nitrogen.

Yee Ive been at war with em since i seen the 1st one. Got some go gnats stuff, an neem, an some of this other stuff a buddy gave me that reeks. An got some yellow stickys In the pots. An i think its the blue suneshine? The #4 mix if im right.. an ive always used it with no issue.. but i never have had this issue. But its good to run into a new problem so i can learn how to fix it.. but i feel bad for my girls...

I don't like any sprays or pesticides personally.
Neem oil I'm assuming you have? That stuff is good. But more effective for thrips and mites IMO. And most effective as foliared.
Check out de. ( diatomaceous earth). Cheap. Effective. Safe for use around kids and pets. You can just sprinkle some on top of medium and and burgers trying to crawl out will be cut the fuck up by the microscopic plankton shells which what de is.
