I'd keep feeding with a veg food for the first 2 weeks into flowering, looks like you have a nitrogen def.
 
Could very well be N def but also could just be genetics. I have a strain that when I switch to flower it will kill many leaves on the bottom of the plant but it will not affect the rest of the plant. Also, if the bottom leaves are not getting adequate light, they will die just the same. Could be a few different things my friend.
 
okay here are more pics more yellowing the after they turn yellow the edges turn brown and fall off i put a teaspoon per gall of epsom salt when i flushed her yesterday my medium has .21-.12.14 can it be the mag still or nitro i need help please

Looks and sounds pretty normal to me as long as it is just the bottom leaves. This happens when the plant realizes it is changing to flowering mode and it draws nutrients that it has stored up it it's leaves to be used to create flowers. When these leaves that were vamped of nutes get weak, they go limp and eventually fall off of the plant or sag. smaller ones are less likely to turn brown. large fan leaves will go brown at the tips first and work their way back toward the stem until they are structurally unable to support themselves. Hope this helped some. Let us know if there are any new symptoms
 
i just got done with a flush and put tiger bloom half a teaspoon per each gallon an fed them one gallon each i hope this should help but heres some pics

you cant flush slow release. and mg sucks for what we grow. toxic sources they use. lawn ferts will kill you animals even. those are for tomatoes. nothing like pots needs.
9 times out of 10 the ph is fuked in MG

check the run off for ec/ppm and ph
 
and flushing for 2 to 3 days is probably going to bite ya big time. only do this once then leave it. things dont fix over night
 
okay thx for the response but i dont have a ppm meter or the other meter but i do check the ph every time i water?could that help do i continue to harvest or what?the yellowing in the 2nd plant in the paint bucket is continueing to the middle of the plant

If you don't have a way to test your ph you are in trouble. Many, if not most, problems are due to improper ph levels. I have nover used soil, but I had issues with my hydro setup when I was just adjust the ph at the beginning of a nute change. I found out my ph levels were rising daily! I invested $30 and got a meter that tells me the ph so that I can make sure my plants saty healthy or if I need to adjust higher or lower. Best of luck
 
Why are you flushing the nutes out of your medium when the plant is begging you for them? Your plant is beautiful other than the stretching stems and yellowing leaves. I would recomend adding a little N and see what happens but not before your plant has used up the abundance of water you flooded her with. It could also just be the plant's way of dealing with your grow room. Always make small adjustments and not the big sweeping ones that you've shown here. If you've managed to grow fine up until now in the same medium then you probably need to add something.

You CHANGED the hours and therefor changed the plant's nutrient uptake and you got a response to that change, right when its supposed to start budding. That sounds to me like you need to add something that she does not have. Yellowing leaves like what you have shown and described sound like N deficiency. Use your head and do some more research next time you plant a seed. Panicking will only cause you to make ill conceived decisions. Good luck.

p.s. If you don't want to mess with ph I would recommend using Distilled water since it is a consistent 6.0
 
never looked at it that way that might make sence if i add a little more tiger bloom but the miracle soil has .21.12.15 npk so im wondering if i flushed out the slow release ferts out the soil so i can add the tiger bloom my ph is fine im just not sure if im over or under feeding them anymore advice would be gr8 because there not improving help please!!!
 
bumpbumpbump well im in the process of waiting for my last flush to dry so i can add some grow big fox farms heres a little update my npk for the miracle soil medium im using now is .21.12.15 slow release ferts my two ladys been in that medium since sprouts and all of a sudden a week into flowering they turn completely yellow at first the tips brown and crisp then fall off ummm im just guessing i mightevd flushed out all the nutes by accident so.....aa.....yeah bump bump bump lets see what happends.should i add a teaspoon per gall of tigerbloom or grow big?

please respond im desprete
 
dude if you look at the fox farms feeding chart you'd be adding, big bloom, grow big, tiger bloom, and open sesame right now. you are not feeding your plants anything by just watering them. they are taking the nutrients out of the leaves because there is none available in the soil. even if you have slow release ferts in there, it is miniscule compared to what the plant needs right now. the plant will always take from the easiest "source" to dump into the "sink". i honestly would look at bulking up what you are feeding but be cautious since you didn't feed as of yet. during veg leaves are sinks. nutes go into them so that during flower they can be an additional source. stop bumping and start reading...
 
example d and e look like the top and mid of my plant the bottom looks like a b c .so its def not underfeeding im overdoseing im just haveing trouble flushing out the miracle grow that the npk .21.12.15 should i really add more grow big and tiger bloom anyway?
