Thank you defiently a relief hearing that
Seriously stummped 20% of my plant looks like this

Yeah, likely just genetics or normal flowering change.

I agree with Dirty.. it appears to be a molybdenum deficiency. The red leaf tips are the giveaway. Molybdenum deficiencies usually occur when phosphorus and sulfur are deficient. Molybdenum helps the plant absorb nitrogen from the air.
Greensand lime will fix this problem, so will tomato plant food mixed at half strength.
Molybdenum is off set by a bad ph? And usually pretty rare?
I check my ph everytime using my pen. and I'm at 6.0

Is this a soil grow? Molybdenum is best absorbed by the roots in soil at pH levels of 6.0 - 7.0... be careful using a pH of less than 6.5 in soil.
If this is hydro or a soil less medium, Molybdenum is best absorbed by the roots in hydro & soil less mediums at pH levels of 5.5 - 6.5

It is a soil grow thank you

I like how rare somehow means it won't happen to me. lol Leaves turning reddish purple is pretty rare to me. I can get purpling out of almost any strain using cool temps at the right time. That doesn't look like what you have. Your leaves are almost "bronzing" more than purpling. I would lean towards a micronutrient problem, some strains are sensitive.

I disagree !!!
It's only happening to one strain and the other is fine....Correct? (I read the whole thread)
You feed them the same......correct?
The pics show healthy green growth and the new growth is fine ..... correct?
If the answers to my questions are "YES" .... your good to go!
New growth is good = plant genetic trait being expressed!

What makes you think that because it's only happening to one plant that this is not a molybdenum deficiency? All plants are a little bit different, I wouldn't expect both strains he's running to have the same symptoms, because they are two different strains. Not all strains feed the same... even with same strains, different phenos can feed differently.. some plants are picky, some are not.
FYI.. an average molybdenum content of 2.0 ppm means that there is approximately 0.2 ppm immediately available to the plant on average. The average MO content in most grow/bloom formulas is around 0.0009%... it will have the lowest nutrient content of all nutrients in the formula. A molybdenum deficiency usually shows up in the older to middle aged leaves before moving on to new growth. Molybdenum deficiencies are fairly common in a some of the citrus and vegetables we eat everyday, but it's a rare occurrence in cannabis and it's usually mistaken for a nitrogen deficiency.
I am also going to have to agree with u. Still gonna be cautious of the molybdenum deficiency. My reason is because a few of the leaves have almost turned all the way pirple a few orange a few yellow and molybdenum shows signs from older to middle leaves this specific issue is random all over. Also the buds are continuously exploding.

So you post a thread saying you have a plant problem. Now you are saying its fine and nothing is wrong? Cause the buds are "exploding". Make up your mind. And now you say you have orange and yellow leaves. So you know its not just normal purpling. Keep agreeing with people saying you're fine just because that's what you want to hear. Good luck
The personl
hey man this is my first grow. The person who taught me is doing this in a warehouse for the dispensaries in Michigan. He came over and told me that this was a strain trait and that I had nothing to worry about as I also said I would keep a look for molybdenum def. no need to state why I handled this the way I did. Thank you for your concern.

I'd say you were throwing out a reasonable explanation to this odd problem. Plant doesn't look right. And the way I see it, this is some new strain bomb diggety or he's got a problem with this plant. My 2¢ is that maybe he should at least give it a little more thought instead of hearing what he wants to hear. Maybe just TRY flushing a little. Or add SuperThrive.
I use superthrive

Flushing can cause more problems than the one your attempting to correct...Simply water it out with pHed water.
Superthrive is snake oil!!! As close to useless as you can get for Cannabis. OH WAIT,,,you like AN too don't you?
Any micro nutrient def is rather rare......98% of all nutrients for sale contain them in amounts that cover your needs. If in soil - then it's even rarer! I have NEVER, in decades of growing, had a micro nutrient issue in Cannabis!...I can force it...but why?
If it was one, it would have to be directly related to what he grows in and what he feeds.....pH could be a contributing factor.....
It's not a Mo problem....
BTW, yes plants can differ in how they feed, (slow vs fast) but, not in what they feed or the ratio's they require !
This is another old an beaten to death doper myth.....
Dude - plants are fine!
