yellowing new growth?

[Guest]

so i got a problem...small oe tho..ive noticed alot of yellowingon the lower leaves..and some brown spots onthem..was told it was N def...so ive upped my floranova grow from 1 teaspoon per gallon to 1 1/2. now ive noticed the new growth tips are yellowing too...is this still a N deff.? how much N should i give it? its about 4 days into flower so im sill giving it grow till the stretch stops..then ill slowly mix in the bloom..like 1/2 then 1/4 grow 3/4 bloom. im just curious how much i should be putting in..i am giving as less as possible cuz i always burn them. now im under feeding them ahhh.

this is the other pic i added with the brown spots

This hydro or soil? I'm assuming hydro.

In that case I would ask what your pH is. This looks like pH lockout, especially since you upped the nutes and are still seeing burnt tips. Gotta be careful though otherwise you'll burn em, and that's always way way worse than not giving them enough.

Get your pH at 5.8 and all should be well.

At the phase you're at I use Floranova Bloom (I actually use that through the entire grow, no need for growth nutes really, just marketing hype). I run it at 6ml per gallon, sometimes pushing up to 8ml per gallon. So if you run close to that, with a dialed in pH, all should be well!

its actually soil...and i dont think its a burn...ive got alot of yellow leaves...this is one of abotu 3 that have some brown...i was told it was dead tssue due to a lack of N. im more concered with underfeeding. was just curious if itis normal for new growth shoots to appear really light green when they frist come out. its under a 150 hps...heres an idea of the setup..its got 3 plants in it now tho not just the one

Yup, new shoots will usually appear much lighter than the older growth.

If you suspect this is a lack of nutes then roll with it... was only guessing with very very limited amounts of info

i'm just chucking my but it seems more like a small Potassium tox....could be you have some salt build up in your soil.....

indulge me and take some more pics plz...
