doesnt look like a mag deff. looks like the plant is sucking the nutrients out,mayby do to a lockout?

in my humble opinion... looks like nitrogen deficiany with a lil nute burn.... heres why... notice how the yellowing only occurs on the outside of the leaf.?? to me that says the plant is pulling the nitrogen out of the leaf at a much more rapid rate than normally occurs during flowering. in addition the outside edges and tips r burt?? definitely nute burn.
RECOMENDATIONS:
flush with water and an enzyme.....next feed water and VERMI T... look it up and find it.... the next feed half strength nutes with a lil veg nutes in the mix and a good B1. make sure when watering u water till u have 15 percent runoff! Also please be aware after using the enzyme u may have more nute burn... due to the fact that the remaining nutrient that was locked out and not "eatin" by the enzyme or flushed by the water is going to b taken up by the plant.....this is jus my humble opinion and in no way implied as right? jus my way... as i say no one knows ur garden better than u! but if my info helps?? make sure to ADD REP! lol b SAFE

how u know that?? experience?? i run soil at 6.3 all the way through 365 days a year.... never had the problem u speak of....

The ideal ph for soil is 6.5, 6.2-6.8 being the preferred levels, but plants in soil do run into more P and MG problems as it goes lower than 6.5. Notice the drop in solubility of P and MG.

thats a nice chart!!! real pretty! but i speak from and of EXPERIENCE......not sumthin i read or heard.... i do this for a livin! and im sayin 6.3 is crackin! the chart is cute though...the plain and simple truth of it is this..... each strain is different... and as such requires different things at diff times! charts are cool for the newbs! but they r jus guidelines.... ANY real commercial grower (ME) gonna tell u that u can do and get away with alot more than the books and charts say! and will never say cuz we aint tellin! but u stick wit it brah....when u can get 2 per light let me know... till then in regards to these tomatoes.... 2per is king!

be very careful of misinformation... jus cuz its written down does not mean u should believe it! nothing is more real or prevalent than real world experience......anything i say i do or have done.... it should b the expectation of all RIU members that when giving a fellow grower advice we should only speak from experience.... as there is enough misinformation out there already... and with the government and just the general secrecy of our field we have enough stress in our lives. Misinformation (propaganda)... tools of the enemy

I dont wana get involved in yet another pH debate so both of you keep it down!lol! Ph is pH, wana make it complicated then do so, wana make it easy then simply add the right amount of lime per soil per water, simples! Soil runoff tells us very little about soil pH, it more tells us what and how much ferts is held in the soil, i.e. too low a pH would mean possible fert build up and the plant cant eat it as quick as your applying it, check ppm runoff from the same soil and if thats high then yep you need to flush.
The guys got lime in his soil mix so he done well and probably why his runoff is coming out good and ppm sweet too. Im guessing just run a slight bit more or higher on the p and k dude and get back to us with how that went. Your pH is as it should be and ppm is a touch low in my opinion but go easy, dont raise it too quick or you may get the reverse.
Try a bit of mag any way, epsom salts should do or any other supplement available, a small bit wont hurt. Peace
As always good luck and keep us posted. Ph noobs can go at it now!lol! Peace

That's why I don't believe it's nute burn like the one dude said. I'm very cautious about over-fertilizing, and I don't like making any drastic changes. I like to have a pretty good idea what the problem is before I just start throwing fertilizer at it or flushing it out. These drastic swings can't be healthy for the plant IMO.
10 days ago I gave her a little extra bloom nutes (NPK 0-5-4), but it did not slow the problem in the least. I would think if this was the problem I would have seen at least a little improvement with the extra feeding. The problem has been progressive worsening for about the past three weeks, and it is unique to this strain. Same feeding schedule as my other strains which are looking as healthy as could be.

because its not a P or K prob.... nitrogen (N)....wich there is none in ur bloom (0-5-4) is what ur in need of.... nute burn occurs with ph issues beacuse at some point in time the nutrients that were unavailable to the plant due to ph become available.....and at that time BURN...... also FLUSHING is never harmful in anyway... on the contrary it is quite beneficial and even necessary in some applications.
Progressive in the last 3 weeks?? Looks to me ur around 3 weeks into flower?? HMMMM did u use an enyme during ur transition?? if not there it is...residual veg nutes still in the medium... addition of bloom nutes.... no enzyme??? poss burn

Ow dude, i hate them insolvable problems especially when its just one plant. Seems like possibly magnesium, is common for plants to want a good dose of mag at one or two points during the grow. Solving this might help if the healthy ones do the same thing as well.
So you upped the bloom nutes a touch, i think your soil, pH and ppm sound good for the plant, runoff is by no way accurate though and neither are some digital readers. What soil, ferts, lights and temps etc etc, maybe some might have other suggestions. I suppose we would all recomend a flush and re nute'ing the soil if all else fails. When ferts dont work i often consider a lock or flush either way but sometimes it is more simple. What levels of grow are you adding with the bloom? Peace

You're bang on dude, exactly 25 days into flower. I had started noticing some lightening around the leaf margins about one week before switching to flower, but didn't pay too much attention because it wasn't very noticeable at the time.
I do a flush the week I go into flower just to kind of clean the slate and make sure I don't develop any lockout problems once the plants are heavy into budding. Figured the flush and re-nute would have solved the problem, but it didn't, and like I said, it's only progressing at this point. However, I've never really like flushing more than twice per grow as I had thought it stressed the plant. I guess I'm wrong on that point.
It's obviously something this strain in particular needs more of, because I'm giving a nice balanced feeding schedule, and I've seen this problem on ALL of these plants (pakistan chitral kush - I should have mentioned this before).
I really don't think it needs more nitrogen, as this plant is VERY susceptible to nitrogen claw, and I'm quite familiar with how lack of nitrogen looks, and this just doesn't seem to be it.
She is certainly a picky girl, but I guess that is how some of these landrace strains can be. Probably not really worth the effort, but I just want to solve this problem now because it keeps coming up, and I should really learn how to deal with it rather than just abandon this strain.
I don't feel like flushing and re-nuting will help, because it would have done so when I switched to flower.
From all the troubleshooting guides I've looked at, it seems to come down to potassium or magnesium. I don't have a really good eye for these things, and half the time I'm just going from an illustration, so that isn't the most helpful troubleshooter tool.
I have some liquid cal mag, and I have epsom salts. Should I give one of these a shot and see if it slows the problem down?
EDIT: I'm not using any grow, I'm going by the Lucas formula, and only using the micro and bloom at 5ml and 10ml per gallon respectively. The last time I used grow with this plant, it got nitrogen claw immediately, it just can't handle it.

IF it is a deficiency, I'd go with Mg. Just for shits and grins, try watering with a tablespoon per gal of Epsom salts and watch them. That way, you wont over fert anything and if it helps, well, there ya go. I noticed that my JH LOVES Mg, and requires more than my other girls about the 3rd or 4th week into flower. I believe it's definitely strain specific. Also, +rep on the way you analytically went about describing this. That went a long way in helping others help you!!
