Yellow leafs by the day. First grow

I' m usin bio bizz grow. Bloom. Top max. But have noticed leafes turning yellow buy the day. Picture doesnt show properly.
 
You said it was your first grow. My advice was to use general hydroponics flora trio nutrients. They are very easy to use compared to advanced nutrients. And general hydroponics does get good results. It's easier to learn with. Then once you have a little knowledge on how your plants react to different nutrients I would try advanced again. They are a better line but they are a little touchy-er. At least that's what I hear
 
Hey I'm sorry ignore me. I didn't realize biobizz was the brand I thought it you were talking about something different. I have never used biobizz. Nor have I heard about it before now. Usually yellow leaf would be a nutrient deffeiency or a ph problem especially if it's a young plant in veg
 
I got tolt not to ph with the biobizz being organic. But i did PH earlier just with leafs getting yellower and it was about 5.6 ph. And i do wished i went with flora trio. Can i change nutes now 6 week into flower or just see it out what do yous reckon.

Oh I didn't realize u were that far into flower. Who told you not to check ph? I know there are nute lines out there that are supposed to automatically ph themselves thru some form of magic lol. but I would still at least check it to see where it's at. Are u growing soil or hydro? If soil that ph is really low. If hydro it's a little low. I don't know much about that nute line so I don't wanna tell u to add ph up cause 6 weeks into flower there's a lot to risk. Also that far into flower I would be nervous about changing ANYTHING, especially something as important as nutes. I know that towards the end of flowing leaves will turn yellow. Maybe your strain is more prone to that than others. On the main GWE site they have charts that show nutrient absorption rates at different ranges of ph for both soil and hydroponic setups. I would check them out if I were u.

Hope this post was a little more helpful than my last one for ya
 
Just looked at your pics. I think those ladies look damn fine. I mean you got a yellow leaf or 2 in there but I didn't see anything super alarming. i would be happy if they were mine
 
You're not supposed to ph living soil unless your water is super high/low ph. The microbes do all the work and basically deliver the nutrients to the plants.

Davey, your plants look fine to me. They yellow up late in flower. It's the natural progression to death.
 
It was the hydro phonic shop who said dont ph and there in soil they look more yellow in better light. Thabks any way

I don't get good pics in my space either. :-( but Royal there said they turn yellow too so your probably good.

Royal Nugs thanks for explanation on the microbes and ph thing. I've never done a super soil before. I wanna try some time
 
You might want to try adding some blackstrap molasses, a tablespoon or 2 per gallon, every other watering. I have read it is good for the microbes in soil grows especially during flower. I have always done it so I don't know results without molasses. Be sure it is "blackstrap" and no sulphur.
 
Is it just the leaves directly under the light turning yellow, or are the leaves lower down on the plant turning yellow too? If it's just the leaves under the light, is it possible it's being caused by light burn?

If not, pH is definitely the first place to look if you start seeing deficiencies. Even in organic composted soil, sometimes you need to adjust the pH if the pH of your water is too high or too low. In a soil setup you want to make sure the pH is between 6-7 for the best results.

Just curious, how long have you been using TopMax? Did anything different happen right before you started seeing the yellow leaves?
