Too Nitrogen or not to nitrogen that is the question.

Quick question and some advise would be awsome. Im halfway through 4th week of flower and it seems my bottom 2 nodes are showing N Def. on fan leafs Yellow/Green I know im probally a bit root-bound as im in a 1.5 gal pot. (space limited) I am feeding old age bloom belive its 5-10-10 she got a heavy feeding last week (2 tsp) and showed a few leaves with burrning tips but nothing bad. No idea on strain looks to be a cross. I know they usally start eating them selves in flowering but not normally this early. I'm in tricomb production now and every thing above the second node is in great shape. What would you do?? Feed a bit of grow or leave well alone?

Thanks some experience would be awsome.

i always feed a lil bit of veg nutes in flowering to stop them from yellowing as i've found most bloom nutes cut down too much on the n and you end up with yellow plants 2 weeks into flower unless you add some nitrogen..

So do you think the 5-10-10 is not enough? and next water add say a tsp of 12-6-6 ?
or do it now to stop yellowing, just had a clean watering just last night or night before.

Thanks for quick answer

i'd add a bit of the grow or w/e you have lying around next feeding.. it surely isn't going to hurt anything ime..

And i would maybe lower ph to 6.5 seeing as you get lockout from cal/mag at 7.0

cal/mag lock out at 7.0??? in soil??? you sure?

Here is a chart I use for lock out. Is it wrong?

i don't ph anything after reading some of uncle ben's posts about ph and soil.. just me though..

Agree I think ph in soil is one of the most bs things but when I start seeing roots out the bottom of bucket I start to check but a good soil and plenty of it will buff the ph its self no checking needed. I take ph so seriously my meter was 5 dollars from home depot. Got a link to uncle bens post for me Im intrested.

Thanks man.

Excessive phosphorus can lock out the N too.

2.5 months or so guessing, Not as bad as it sounds.

veg for 4 weeks at 7 inches I put into flower, shes about 20 inches now. I have a pic but still looking for stupid usb cord.

Sorry but pic is sideways. (on another note does anyone have link to uncle bens ph soil thread. I really want to read it, and cant seem to find it.)
Heres a Pic Soaking up all the advise keep it coming, Planning on adding a tsp of 12-6-6 next feed to boost nitrogen. I keep reading that N is bad in flowering cause it causes slow Flower growth. How can this be when a precent of the flower is made up of leaf material? B.S. right?

Hmm i always heard lock ou was at 7 for cal/mag thank you apparently i was misinformed...i just know 6.5 is best for soil as the most nutes are available in that range

I say nitrogen. Somes strains eat it up in flowering and ime if your showing slight deficiency now in 2 weeks half your leaves will be yellow and falling off. strain dependent tho...me id N it up if your sure thats the problem sounds like it could be. Nitrogen the entire leaf will yellow even and fall off a perfectly healthy but yellow leaf. Phosphorus it will crinkle brown at the edges and tips after it yellows then falls off.
