Is it normal for there to be this much yellowing during flowering?

EDIT: For most recent pics go to the second page, near the bottom

Hi my plants are in the second week of flowering and I know it's normal for the plant to get rid of the leaves it no longer needs but I have been picking 10-30 yellow leaves off my plants every day. It's starting to affect the bushiness of my plants. Any ideas if this is normal? Here's some more info/pics:

-Outdoors
-Temps between 80 and 100 (on hot days)
-I'm on the west coast so humidity isn't an issue
-pH around 6.8-7
-Watered every 2-3 days, regulated by a moisture meter
-Last fed 1 week ago Bio Bloom nutrients, 2 teaspoons to 4 gallons of water

The first pic is after i took most of the yellow leaves off

Not that early. picking the leafs accelerates the process, its trying to use up the N in the leafs and you keep removing them as soon as it can get any, stop that and fix your PH ( is that measured @ runoff? ) / feeding. You probably started the bloom too soon mix in a little grow so it can get more N id water next time with the grow ( veg nutes )

i actually didnt buy the grow nutes, as the soil they are in has plenty of NPK thats supposed to last another few weeks. and the pH is actually not measured at runoff, its just the reading i get when i push the meter into the soil and as far as i know, it's normal

You probably vegged 5+ weeks right? Those preloaded ferts are probably long used up and converted into salt build ups ( if you havent flushed ). I would flush and then water with like 1/8 strength MG tomatoe, its like $5 and itll give you a dose of N, I used it on a whole grow it wont hurt to use it 1x on a N def. plant

Fertilizer companies over state the length it lasts. IE my dad uses dynamite plant food for orchids, says to last 9 months wont last more than 6 in real use

The problem with pre-nuted soil is that guys thing they don't have to add anymore nutes, so by the time the plant starts flowering, the soil is almost devoid of nutrients. And now the plant is hitting its stride, (which most do around the third week of flowering, thats why it's recommended to use pk boosters during the third week) and pulling what little nutrients are left in the soil.
The only thing you can do is what Lysol recommended. The yellow leaves will never recover so those will fall off.
Btw, I too use MG Tomato plant food in my outdoor grows. And my soil is the pre-nuted stuff from Walmart or Lowes, depending on who's got the sale. So I do know exactly whats going on with your plant. And so does Lysol.

sorry i should have been more clear earlier. the plants were recently transplanted into that soil about 2-3 weeks ago, but you still may be right since they say the nutrients in the soil last only a month. im still hesitant to feed them any more nutes because after i gave them bio bloom one of the plants (the big bushy one) showed nute burn and is still continuing to do so even after 1 week + flushing.

 

[Guest 18340]

I'm looking at that middle plant. Is that buds I see forming? I can't really tell clearly. Anyway, the plant is pulling N for sure. It doesnt necessarily need more pk, just N. Thats why you probably burned it when you hit it with bloom nutes.
Since you transplanted them just prior to flowering then theirs enough pk for the plant, But not enough N. So, its pulling N from the only source it has, it's leaves.
Mind you that flushing the soil will also wash out the nutes that came with the soil, not just what you added.
It's not too late to transplant and start over. Not recommended, but not too late...

yeah that's definitely buds forming. what you say makes sense so i went ahead and took your advice and gave them about 1/2 teaspoon of MG foliar fed from a household water bottle. do you think thats enough or should i also pour some into the soil? if so, how much? bear in mind im not trying to burn them again as MG also contains plenty of pk

 

[Guest 18340]

Yeah, at this point I would be concerned with burning them. The reason I asked if that was buds I was seeing is that buds tell me more about the plant and what stage it's in. I hesitate to tell you to go ahead and add any more nutes to your soil because I fear you'll burn them (I know, I'm repeating myself).
Since you have 3 plants, experiment with one of them and give it a 1/8 dose in its water and see what happens.
That one with buds looks to be later in flower than the other two. What strain are they and how long is the flowering period for them?

Are you using biobizz bloom? If you are using biobizz, you need the grow. The bloom is not designed to be used on its own, it doesn't have anywhere near enough N. The biogrow and bloom are meant to be used together all the way through flowering. You are infacr supposed to increase the grow slightly towards the end. I use biogrow allways on soil, i really rate it, and love the fact you can use it all the way through flowering.

My plants allways need extra N in soil, particulary during the first few weeks, when alot of N is taken up in the stretch. I can often be adding more mls per litre of grow than bloom for the first few weeks of flowering.

I'd grab some biorow and start adding that, doesn't matter if you add it on its own if you're scared of over-feeding. I switched over from the biobloom though to biocanna flores, as it didn't have the oopmh i was looking for. Would never stop the biogrow though on soil, very good stuff indeed in my opinion.

From left to right the strains are: Blue Cheese, Sour Diesel, and Purps and their respective flowering periods are 9 weeks, 10-11 weeks, and 8-9 weeks.

yeeah i am using the bloom but not grow. i found out i needed both when i got the feeding schedule that said the same thing you did, feed all the way through flowering. i didnt get it at the time because i didnt wanna spend the extra $20 since i figured i could just give them a small dose of MG for nitrogen and all that good stuff but now i might bite the bullet since it sounds like you're gettin good results

Also the BB grow supplies the K. Too little K and your cured pot won't burn well.

Okay so i just checked on my plants and its been about 5 hours since i sprayed them with nutes and one of them is already showing nute burn. it was about 1/2 teaspoon all purpose MG to one bottle of water split between 3 plants...hardly any nutes at all. im thinking since it looks like a nitrogen def i will buy just nitrogen so as to not burn them with anything else...

Damn dude, I was afraid of that.
I'd really like to know what others would do in this situation. When I encountered the same problem as you're having, I just let it go until the end. Crazy amounts of leaves fell off and yield suffered.
Btw, curious as to what brand soil that is you're using. Whats the NPK?

 

[lysol]

I would just keep feeding like it was not yellowing ( dont start feeding more frequently! ), just mixing half grow half bloom until the yellowing stops. My plants lost all their leafs and looked naked but still get upwards of 100g, just try not to screw up anything else like overwatering, dont spray em during flower ( i wouldnt ). mix the MG really weak, 1/2tsp to 1 liter water is wayy strong. try 1 /4 to 1/2 tsp per gallon or 2, I'd Ph the MG to like 6.5... the MG is really strong because farmers usually spray it on huge fields, you have 3 plants.

You will get more leafy bud but it beats nothing, youll have extra trim ( those little sugar leafs )

 

[green_farmer]

Hey mine do that each time I transplant or move light rooms or out to the sun. From what I saw, doesn't look like too much loss.

Oh yes, I feed grow nutes all the way through flower (plus of course, PK). I'd prefer to use less nutes than too many - always err on the side of caution. You can always add more of a weaker solution.

If I spray my plants with nutes, it is always less than 1/4 of recommended feeding rates, because of nute burn (think I got caught once before, years ago). Never had nute burn since with this policy from foliar spraying.

However, I am not growing your strains.

Are you keeping the plants well hydrated? I can't see any trays underneath... My girls also can look like that if I forget to water them...

Good luck!
GF

 

[green_farmer]

BTW, what time of day did you foliar feed them? If before 3pm...the sun may be burning them.

And during summer (and winter if a warm day), my girls love a drink every afternoon...and a tray underneath to keep them topped up during the heat of the day...

Another trick I use is to cover up the pots so the sun doesn't boil them. Where I am, the pots can heat and steam up in the heat of the day without protection, though brown pots aren't too bad. Depends on your location, but if the roots get too hot - it can create problems.

Cheers.

 

[anarchy2465]

I'm in California so it's not unusual to have 100 degree days. I just don't really know what to do about the heat though. I moved my plants out of direct sun and that's about it. I have a moisture meter so I tend to think they aren't over or under watered.

Another question: When feeding miracle grow should I feed 1/4-1/2 teaspoon to a gallon per plant or should I divide this solution among the 3 plants? I usually divide my solution between all three and i still get some nute burn. Do you think it would be a good idea to buy just Nitrogen-only nutes? 12-0-0 or somethin

 

[lysol]

If you can get just N that would be better, feed 1/8 - 1/4 tsp per gallon to start ( if using MG ). 1/8 if you are mixing it with something else. only water until the pot feels like it has a lil weight, the pot should never really get heavy to the point of overwatering, so I guess water until your meter is right
