Yet another flowering question

[BlackWidow]

hi yall
iv been flowering my girls for about two weeks i think
and everything is going great and i see some good results.

few days ago iv noticed that 2 of the lowest largest leaves on one of my females has turned 100% yellow.
i pulled them out is that normal for a flowering plant?

I used to feed them at veggin time with 6,2,4 NPK NUTE.When i started flowering i used 2/3 of the veggin nut and 1/3 of the flowering nute because it has a low N value (4,3,5 npk) then i swiched to 2/3 flower nuts and 1/3 veggin.
now i am not feeding due to small nut burns on all of my plants.

I dont have a camera at the moment sorry
any ideas what can be the problem with my girls?

I think its a little to early for the leaves to be yellowing. It is normal when the plant is say 6weeks into flower. Did you flush after the nute burn? Whats your ph? Its prolly starting to yellow from either lack of (N) or from lock out. I would flush let em dry out and give em full strength flowering nutes

but if i flush them and give them the flowering nuts that i have wich has low % of N wouldnt them starve from N ?

altough right now i am not using any ferts

i am scared to flush them cuz their heavily lst'd ]=

Whats your ph? There may a lock out causing the n def. and dont be afraid to flush with ph balanced water. Your 2 weeks into flower its time for flower nutes and some N is better than none. In flowering plants they need N but not a lot so feed em what you got. Imo your NPK values are a little low I think. What nutes are you using anyway? More than anything ph may very well be causing your problem. Its hard to solve your problem with out pics and knowing your ph and enviorment. Also what kind of ventalation do you have? Lots of things could cause yellowing leaves.

started feeding them again with the flowering nuts..hope that will work...
thanks

It is most likely that the tops of your plants are absorbing most of the light leaving none for the bottom leaves. If you want to correct this you can shift the branches around to let more light seep down to the bottom.

I hope this is helpful,

I agree with haze, sounds like nitrogen is taking over. by using veg nutrients for the first week of flowering will help give the plant enough to last through flowering as long as you suppliment it weekly with small doses added to your bloom nutrient. if your bloom has no nitrogen or small amounts.

Flowering plants do not just switch over to flowering overnight it takes a bit of time for them to hit there spurt and switch over to flowering.

Have you also been testing your ph?

But if ill give them the veg nuts now wich has a little more N then the flowering nuts wouldnt it slow down the flowering procces?

No, that happens when you add to much nitrogen. TO much yes will slow it down but if you add a little to ease the plants from using stored nitrogen you will not cause flowering to slow down. You would have to add the same amount you would use in veg for it to cause issues.

Using 1/2 the amount will ease it from yellowing. Because if you know this or not your plant has stored nutrients in the leaves and it does use nitrogen in flowering and the reason for yellowing is because bloom ferts don't have enough and most of them are not made for cannabis. Cannabis still use small amounts of nitrogen but not a lot..... so it goes to its storage in the leaves when not enough nitrogen is present so by adding the small amount it needs it wont use the stored nutrients. which is where you get the yellowing from.
