hi anon.
take a look at the tips. my gues i'm no expert is small over fert or ph lock out.
but not light but a bit more info on your part will get you more info I.E. lights, temps, method ,age and medium . please give peaple some thing to work with then than can realy help.

I agree about the over fert / ph lockout possibility. Are they well into flowering?hi anon.

ph imbalance/fluctuation is my guess...
pH Fluctuation
Both of these leaves in figure 3 and figure 4 are from the same plant. It could be over fertilization, but more likely it is due to the pH being off. Too high or too low a pH can lock up nutrients in the form of undisolvable salts and compounds, some of which are actually toxic to the plants. What then happens is the grower then tries to supplement the plants diet by adding more fertilizers, throwing off the pH even more and locking up even more nutrients. This type of problem is seen more often in soil mixes, where inconsistent mixing of the medium's components leads to "hot" spots.

I did have a bit of a fluctuation on ph yesterday or the day before. but it was only on 2 leaves on 1 plant. I looked for insects and negative. Ph got up to like 6.4 the other day, and I dropped it back down to right at/under 6.0 I am thinking that is what it could be. Hoping so anyway. Im sure if it is, it will correct itself. The rest of the plants look wonderful and healthy though.

so you must be growing hydro, no? any more details? i've had bleaching, it isn't your problem.

Yes, growing in hydro. using entire fox farm line of products. im on week 3 of flower. ppm is 1260 and the ph is usually at 5.8-6.0 the other day it spiked up to 6.4-6.5 for a few feedings before I caught it. I re-adjusted and it seems that may have been the problem. You dont really treat that right, just re-adjust your ph and keep it steady from there eh?

i'm wondering how big your rez is, if you use one? small rez's can easily cause huge problems with ph. here's something that can explain a little about ph.
EC goes up, pH goes down = Plants require less nutes
EC goes down, pH goes up = Plants require more Nutes
EC Stable & pH drifting up, = Equalibrium = Good thing!

ppm stays stable and ph drifts up. so I know im in the good zone, but the fluctuation occurred after I changed the res, then had to go to work and couldn't monitor the changes properly, by the time I came home, lights were out in the tent and I didnt get to see it was too high until the next morning, so it was several feedings with too high of ph. now everything is straight and Im sure in a couple days you wont be able to tell what happened at all.
Check out my journal for more info on my system and some pics on the latter pages.

i checked out the link and couldn't find a number for the size of ur rez. it looks like a couple gallons at most. if you have several plants feeding from this, then your problems will get worse as the plants get larger. ideally, each plant should have 5 gallons. this will really make your ph more stable.

Yeah, I'm only working with an 8 gallon res. So yeah, I just have to monitor it closely. I got slack and they paid the price in two burned leaves. That was my warning. lol.
