Please help asap week 6 auto polar express bottom leaves are turning yellow !!!!?????

Week 6 then been doing really good this is my frist grow cfl I'm useing I just switch to to flowering nutrients im not sure what's going on any help would be great this my frist postso I have to figer out how to post ppictures

Plants are doing good man,u have nothing to worry about yet!!!
Give us some information abouts ur medium and feeding so we can give u some help/advise!!!

the way those are lightened up some from the top some from the bottom.. were they more yellow before and start flushing back green?? if they were yellower and flushed back green you probably just have a pheno that likes N. i've had plants that i had to give N right till the end...but they look good...

I'm just useing FFOF and fax farm trio nutes the red pot I just gave tiger bloom and big bloom and moallas at 6 weeks I always worry about the ph levels I feel like I never know what the coler or 6.5 is or always secound guess my self this is my frist grow I'm new to this I just do a lot of research I think to much some times

right now it looks like its only the bottom and low leaves that are turning yellow which is normal those dont do much for the plant at this point since they dont get much light so it will pull nutrients out of them prior to shedding them and is normal. When the petioles (stems attaching leaves) are brittle and break easily from a light tug on the leaf they are ready to come off the plant.

If yellowing continues on higher parts of the plant and/or if the plant wants to keep the leaves (petioles do no not become brittle) then there is an N deff. But looking at the rest of the foliage on them (and the ffof) I dont think there is an N deff its just shedding the leaves.

Thanks for all the good info ....yea there not much room in my grow box they kind got to big for it so it probably is the light what would a bad ph do because I'm not sure if the ph was good I can never get it right I had a big issue with the ph when I mixed the tiger bloom and big bloom

And Boston I need some help with the n youean nitrogen right? Could I use grow big for nitrogen or do I have to go to the hydro shop and get some nitrogen mix ? And how do you test your ph I don't know if the drops are very profession I haven't been in the hydro shops so I don't know how much the ph pens are or if I have the budget for one ?

yes Nitrogen.. i say because it looks like they flushed back green.. if that is the case you can fix it by adding a little extra grow nutes. most of the time myself i will just add something high in N like fish emulsion/coffee grounds/urine etc but until you become comfortable with your grow just stick to what you have.. this problem is no big deal (if N is the case) and can be fixed any time.. you don't have to give it a tone of N to quickly get it back.. just add a little extra grow next time you feed.. if you see the leaves flushing back green.. this is your problem .. but do it slow the plant has plenty of N in the other leaves and it would be better if the lower leaves got a little yellow then it would if you burn the plant.. as far as your PH.. you can get a pen on ebay delivered for under $10.. i hardly ever even PH anything anymore.. since i switched to 100% organic.. your PH doesn't have to be exact 6.5.. your plants don't appear to have any lock out.. they both look very nice.. you might want to consider harvesting the main cola on the one in the red pot when it's done and then lower the light.. and those lower tops will put on more weight

Yea I thought it might have been a nitrogen when I frist stared researching... i didnt know you can use cofffe grounds/urine.. when I add a lil bit of grow nutes with just water or can I mix it in with the flower nutes to? tonight I have to water the red pot with just water so maybe ill add a lil in there tonight and see if its coler comes back because they are a lil more flush back yellow when I look today..and really this my frist grow so I don't know a hole lot but do you mean harvesting the main cola early? And thanks man I tried my hardest on this lil gals your info great helpimg out alot

you can either or add to nutes or with this watering.. you can use a little this watering and if it flushes back put a little w/nutes next feeding also... it doesn't have to be early (but can be).. when the main cola is finished you can clip it and lower your light for another week or two and those tops will put on more weight.. you have some height on that main cola and it's still gunna grow a few more inches.. it's a kick ass job though first grow or not.. good for you
