Unsure on yellowing leaf?? pls help!!

Hi all.. have a uk cheese grow going on but have an unknown strain of bagseed that seems to be lacking in N but im unsure..

had a problem with this plant for nearly 2 weeks in all i guess... i have 3 plants in flower at the moment.. 2 uk cheese from clones and a bagseed.. Now the cheese is fine but the badseed just seems to be yellowing and 2 days ago i transplanted into fresh pot as i know the problem is not over feeding or ph.. also the soil is the same for the cheese but they are fine! When i transplanted i flushed and gave very mild nutes with more n and epsoms

To me it just looks like lack of n... so should i give it a stronger dose..?? new growth seems ok.. and maybe 2 days is not enough to see much change?? The slight burnt tips are from the enviro's i might add too!!

them pics 21 days!!!! now 23

When you change to flowering nutes the level of "n" is very little to none therefore the plant uses up its stored "n" and the fan leaves turn yellow. Sometimes this happens faster then others. Sometimes they are pale yellow, sometimes bright yellow and somethings they stay green.

normal yellowing, but you can add something like fox farm grow big , like 1/3 strength water it in there and it will give the plant enough nitrogen to keep it dark green till the end of flowering. but the plant goes through a massive change during the flowering. those look good.

thats normal during the flower period. the plant is using up the nitrogen. you can add something like fox farms grow big to give it a nitro boost in the beggining of flowering to keep em green till the end when the whole plant just changes completely
mine are like 14 days or so in to flower. the lower growth is starting to yellow. but its normal. i am using the grow big nutes and this is the only yellow one on the plant. this fox farm stuff is just amazing. im feeding these fox farm tiger bloom and grow big and its working great
what kind of light you using?

easily a nitrogen deficeincy.
phosphorous is purpling of the leaf and stem.
then potassium is the tips/edges of the leaf appear burnt, as if leaf got too far into light.

so u also think its pretty normal.. well ts good to know.. u can check my thread to compare it with my uk cheese.. think the link is below in my signiture... i hope..lol thanks for your reply too also im in very small space so using a great T5 rig and some Envirolites.. i know im not a hps grower but still i think im dong ok for what i got.. check my grow and feedback would be appreciated

So do i just add grow nutes that are higer in n??? or just feed more of my normal canna flores?? or just not worry about it??? even tho i will?

wow i have to say i just looked at the link to your grow man and wow. it is awsome. great job. i take back any advise i gave you because you obviously know what your doing brother. all i can say now is that i didnt know i could use the stuff i use now untill i talked to a lady at fox farm. thats where i learned you can add n to your grow pretty much all through flower and it will stop yellowing. but some strains yellow early. i had a plant that was bagsead but it yellowed early and still came out awsome. they yellowed but did not turn necrotic.

It is NOT a deficiency, it is a normal process of flowering as expalined many times before. By the end, many of those leaves will be dead, and many more will be yellow, don't worry. Plant looks good and strong there! If you really want to hit it with 1/8 strength veg nutes every second week. I usually give them veg into my 5-7 week of flowering, then no more until the next grow...

thanks for you input mate


U say its normal and im well aware that plants start to yellow towards the end of flowering.. but this started one week into flowering and progressed.. we now half way into week 3?? just seemed way to early for it to be sucking up its own leaf goodness... thats why i was bit worried... and most people have said its an N def!!! and if they have N def early on in flower it ruins yield and potency.. what are your thoughts on that?

They look pretty hea;thy... Again, you can hit them qith a low nitrogen concentration every 2 weeks if you are concerned..
