Nute lock?

One of my plants is getting yellow leaves at bottom going into third week of flower. I know some yellowing is ok but this is starting to move up higher. Should I flush or wait it out?

you should feed High N nutes. you have a nitrogen defiency.

Leave them alone.

NO!!!

Do NOT give high N to anything in flowering.

explain me why plz.

Those look good & healthy, man (apart from the yellowing). Can't help I'm afraid but I'm sure someone will be along to give you the ins and outs...many helpful folks around here.

are you growing in dirt? im going to assume yes.Add garden lime to the soil.It could be a PH problem or cal mag problem of both.Garden lime will add cal to the soil and PH it.
The only other thing ive seen do that to a plant is when it has damage to the terminal root.Always put a couple of table spoons per gallon of dirt in garden lime in before you ever start your plant in dirt.This will help avoid problems before they start.

Weedmart is correct it is a N def and the plant needs more N. A yellowing plant during flower means a loss of yield. Keep em green till the end. Yellowing during flower is natural is just plain BS.

most of the time,yellowing during flower is caused by low N fertilizer as «bloom nutrients».Most of grower change to «bloom nute» as soon as they switch to 12/12 but this is an error and will lead most of time to N deficiency at mid of flowering. feeding with «veg nute» the 2 first week of flower will tighten the nodes and keep your plant healthy until the harvest. for a 100% sativa I would even feed with «veg nutes» until 4-5th week of flower.

Well it has been getting 8-9-6 almost every week, even into flowering. I was going to switch to bloom 3-12-8. I still think it might be "locked". I will try lime first and then add N after a few days if nothing changes. Wondering about flushing.

I'd have to agree with the n def.

It was my understanding that getting too much N during flowering would retard bud growth, and that some yellowing of the plant at this stage of life was normal.

Your plants look healthy.

If I'm wrong, I'll stand corrected and learn something.

you're wrong. it's a myth. N during flowering is needed to keep your plant healthy. yellowing is always a sign of unhealthy plant. as stated in another post , lack of N = poor yield.

you should do the opposite, trust me. if you add lime and it doesnt work, then you will have to add dolomite to increase ph... lol... in general,soil and soilless are pre adjusted to 6.0-7.0 and it's pretty stable so you dont need to check your ph as you do in hydro... just feed them light with something higher in N than P and K and observe.

I'm not aware of any credible source claiming that normal lvls of n retard bud growth. Leaves yellowing and dropping from the bottom up is from the plant cannibalizing chlorophyll from the lower leaves to use in new growth. It is caused by n deficiency.
If the plant needs n enough to eat itself to get it, I cant see how it would hurt to give it some & let it hang on to it's leaves a bit longer.

I agree, with the nitrogen dosage but the question is why? If your other girls are healthy while she yellows this tells me Lockout. You may be using the correct dosages. Ph swing can and does cause lockout all the time. How positive you heave kept it in that range? From the looks of the inner shoots they look really dark so its a combo. Flush the shit out of her then put her back on half strength. This will not hurt the other ladies in the same res...

Normal levels is quite vague IMO when it comes to nutrients. High level of nitrogen has been linked to low thrich production. Why leaves yellow...has many reasons. In this case it has nothing to do with normal, if this was normal then the other girls would also be doing it also. A good grower will know when to help out. To remove the leaves correctly you must know when and why. Helping your plant with removal at the right time, keeping her energy focused on buds...JAS

Ok, the internet is full of myths, do you have a good reference to support your claim?

If I'm wrong then I'm wrong, but if you're telling me that I am, please back it up.

yes there's a lot of source, but I wont lose my time trying to find it for you.I've already done my homework. I shared my opinion , now it's OP choice to do what he want. back up my advice? I dont need to , competent growers will all agree with me. if some don't well .... I'm sorry, you lack of knowledge/experience.

If you make a claim to a fact, the onus is upon you to back up your claim if you intend to retain your credibility.

fuck credibility lol it's internet dude, it's overrated. do your homework and do a lil research on the subject , you'll find your answer.
