Sometimes, and only sometimes in the first week of flower it gets really yellow.. starts with the new growth works its way outwards.. Usually about a week in or maybe two it seems to go back to yellow. I can get pics soon if will help. any thoughts?

Generally that's an calcium, iron or zinc deficiency if it starts in the top growth and works it's way out and down.

So it starts in the center of where the buds are formed and works its way out.. The pic of the Iron looks most like it.. I'm using some local store ferts in veg that are 20-9-20. When I switch to flower I use advanced nutrients ( bud ignitor, big bud, bud connoisseur) I'm sorry about the pics, the plants i was going to take pics of is mostly recovered, I just put more in flower and just starting to see the change. Ill put pics up soon.

Might want to try a simple and complete 3 part all the way through. Either General Hydroponics Flora, or Cutting Edge have both produced fine results for me. Never a yellow leaf. Check out my grow below with Cutting Edge.

Also, check the PH and TDS of your waste water. Most just check what goes in. Checking what comes out is far more indicitive of what's inside the medium.

There's your problem and here's an explanation: https://www.rollitup.org/marijuana-plant-problems/158144-never-ending-abuse-phosphorous-bloom.html#post2032066

Failing to understand plant nutrition while buying into some shyster's N deficient products is not cool.

Another one bends over and takes it in the hiney ho! http://shop.houseofhydroponics.com/Connoisseur-AB-1L-BIG-BUD-1L-get-1L-Bud-Candy-FREE-2300013.htm

Sorry to be anal, but this thread should have been started in the Plants Problems forum.

IMAG0090.jpgHere is my next batch doing the same thing, this is second day of flower.. Getting really yellow.. Is it just micro, or is it just lacking all food in general?

Did you transplant from small containers to much larger containers just before flowering? I've seen people make this mistake before. Transplant a 1 gal. plant into a 5 gallon container and you still have a 1 gallon plant. This can lead to overwatering/feeding. And it looks & sounds like that's the case here to me.

im on my first grow and i had yellowing problems also i thought i was either over feeding my girls or nute burn but i noticed the humidity was very low on em and once i got a humidifier they jumped up so if its like high desert so cal that could be a the problem.

I told you what the issue is. You need to examine the total NPK values and you'll have your answer.

I have seen it a million times - rather than learn what makes a plant tick, you'll watch that plant turn yellow, drop most if not all fan leaves large and small and will lose the plant rather than take corrective action. Why? Because the label and/or The Herd said products XYZ is the bomb. Sorry, but that's what snake oil bloom foods do - induce N and micro deficiencies.

Thanks a lot UB! I definitely think you hit it right. I"m going to start adding some K to the first few weeks of flower. I did also repot about a week before flower, fell behind and was in too small of a pot.

More K? I give up. :) You've got a nutrient antagonism thing working. If you would find out what the total NPK values are, as I requested, we could have an intelligent discussion regarding your problems. Here, read and STUDY this: http://www.totalgro.com/concepts.htm

Once you go into a flowering mode root production is put on the back burner. Repot and have the plant established (as reflected by new growth) a few weeks prior to flipping it.

Good luck,
UB

if you would have bothered to click the first link UB left, you wouldn't have made that statement, he clearly told you that you have a nitrogen deficency because the nutes your using have a low N in the NPK ratio
