possible nitrogen or iron deficiency professional advice needed

ok guys so i have just flipped my plant to 12/12 5 days ago. i have noticed today that my new growth is coming through very pale. when i flipped to 12/12 i also started using transition nutes so 1/2 nova grow and 1/2 nova bloom i also added a little koolbloom.

what im wondering is should i have not changed my nutes yet? would the stretch period be considered aggressive growth not transition? if so this is probably just a case of nitrogen deficiency. this plant does like a lot of nitrogen. none of the lower leaves are yellowing at all though just the new shoots.

or could it be possible that i added too much phosphorous in the koolblom causing a iron lockout? as from what i have seen in my research this is very similar to how it looks as well ph is fine and ppms are at about 1400ppm

heres some pics hopefully someone can help










^^^^^^THIS ONE SHOWS IT WELL^^^^^^^

ok so the photos arent great but u can see the centre or apex of the leaves are very pale yellow on the new shoots and the new shoots are just very pale all round.

thanks guys

bumpity bump bump

come on guys really want to get on top of this before lights out today so it doesnt get any worse

can't see shit. put an incadescent in there while you take pics.

It's nearly impossible to see what's what with those pictures. I'm guessing it's just the normal sort of yellow tops you get at this stage. Does it look anything like this with the lights off?

yes it does look a little like that so i this just normal at this stage? was i right to start adding bloom nutes already?

Yeah it's all good. Looks like maybe you could use some Cal Mag. Some leaves look like they may have a little bit of the twist to them, but it's really rather hard to see in these pictures. Overall they look fine to me. I switch to bloom nutes the same day I switch the lights...I add a little bit of grow formula in the third week of flower as the stretch is ending, after that they stop needing as much and usually stay green through to the end. If not, then next go around I'll go for weeks 3 and 4, but no more than that.

thanks laserbrn yeah i had a calcium deficiency but im pretty sure i have that under control now. i already started treating for a possible iron lockout anyway by flushing with flora kleen and im going to take her up to 1600ppm now so that should give her a little extra n if she needs it (shes a very hungry girl, i had no intention of running such high ppms at this stage but she keeps asking for it) and im going to leave the koolbloom out this feed just in case. hopefully that will get her back on track if there was anything wrong at all lol. there probably wasnt im just a nervous noob. i have done loads of research but nothing can prepare you for all the little quirks that u encounter in your first grow

What type of light and how close
?

Yeah, they look fine. 1600ppm's is huge. What strain is this? I don't think you have any problems here at all, sit still and watch the show.

600w air cooled hood and it is about 30cm away i think without measuring it. its been the same distance for a while and it hasnt given me any problems et. i did actually have it a little closer to the screen but i moved it up a couple of days ago before i went away so that they wouldnt burn if they grew more than expected.

its barneys farm laughing buddha and its a total nute pig. i have been using scottyball's method of monitoring the ppms and adjusting accordingly and she just keeps on asking me for more. and believe me she is using every little bit of what i give her. im usually changing out the res every 2 days. (its only about 10 litres) she drinks about 3 litres a day and the ppms have been dropping significantly in that first day usually by about 300 or 400ppm so the next day i add back 3 litres of plain water check the ppms again and then the next day i check and see if the ppms have dropped again from yesterday if they have i do a res change and bump the nutes up usually just an increase of 100ppm at a time but at the moment shes really seeming extra hungry. if i dont keep up with her she starts showing deficiencies straight away otherwise i would be starting to worry about the high ppm levels but there is no sign of over ferting at all so i will just stick with what im doing for now unless any one has a reason that i shouldnt im always open to advice.

Try cutting back on your nute ppm a little to make room for 1 to 3ml of Calmag per gallon of water. Get the GH Calmag if you want to keep it brand consistent.

edit:
If it's growing noticeably every day, I doubt it's a deficiency of one element caused by lockout of another. Probably a more common problem like N and/or mag def. But if it's a shortage of iron, most calmag brands should help as they include traces of iron as well.

It doesn't really look like you have a serious problem if a problem at all. Just kiss 'em with a touch of calmag.

thanks lordjin i appreciate u dropping in. i will check her in the morning and assess the situation. but yeah i do need to get some cal mag. i had calcium deficiency start to show earlier on but it dissapeared once i ncreased my ppm but still i think with the r/o water i need to have some on hand as a back up

Oh, dude. If you're RO filtering your water def supplement with calmag immediately per the GH calmag instructions. There's your problem right there. The RO process filters out everything... including vital trace minerals and iron. You gotta put that back with calmag, bro.

edit:
And it's a known fact that air stone bubblers and submersible magnetic driven pumps deplete iron continually. That's why you have to keep dosing with calmag at each water change.

this will do the trick

thanks again lordjin i assumed that they put all that crap into the nutes but i guess not

Nova is a pretty balanced all-in-one, but you have to assume that the manufacturers are making the base mixtures based on a pretty broad metric of possible water conditions... I don't think they're taking into account fully the nut jobs out there who are making their water naked of everything with RO... not in the base anyway. There are hard water nutes, but no soft 'naked' water nutes... Lol. That's why Calmag exists as an additive, tho. That's how the manufacturers have accounted for us RO users.

Yup you are right, they def have some twisting and cutting going on. Cal mag is the way to go
