Please help me Diagnose.

Hello all,
Just curious here i need some help diagnosing my plants. Im about 3 weeks into flower and this yellowing is starting to drive me nuts.

I keep my ph around the 6.1 mark. I let it drift down to about 5.8 then bring it back up to 6.1.

I use general hydro three part flora series.

Its a Deep Water Culture Under Current system.

Seed is feminized white widow.

Looks like a n def to me

Did you keep running your veg nutes into the first two weeks of flower? If not its that. ^^

Yea i mean N as in Nitrogen haha, time to start taking a wee in your res

I'm lucky I have a good hydro guy. He told me this. I think the dumbed down version is that the plant uses a lot of N during the stretch (as it does while vegging) so after the flip it needs the grow nutes (high in N) to feed it properly. After the first two weeks of 12/12, the stretch basically slows/stops and the plant concentrates on the buds, therefore you begin with the flower nutes. I'm sure someone will correct me.

Dude that actually makes a ton of sense....... Gotta love the tribal knowledge! Thank god for these forums, we get to share that knowledge!

Glad I could help. I'm on day 7 flower of my second grow. My first was a disaster. It's how we learn brother.

Have you been documenting your grow?

That link isn't working by the way.
I'll briefly start with my first grow.
I had 5 autos all the same strain. One turned out to be male.
I chose the wrong medium. Some crappy potting soil with no drainage, insects, and way too hot.
So I waited about a month before I fed for the first time. It was too early and burned them. Then I Waited too long and really starved them. Then fed them at full strength snd every watering and almost killed them again. It was a nightmare.
Now the 2nd grow.
I'm using freebies.
C99 from Blimburn
Mozzerrella from G13
GSC from BCBD.
I'm using pro mix hp, botanicare pro grow, bloom.
Tap water. 600w hps.

In the propogation tent is
GTH#1 from rate dankness
Maple leaf x black domina from expert
Tutankhamon from pyramid.
I took clones from the flowering girls yesterday to practice as I've never done it before.
Sorry didn't want to hijack your thread but you asked. Anyway you motivated me to start a proper journal. Thanks.

My .2c
Up your macros. It doesn't look like N issues.

Use age old organics kelp.

Can you elaborate on Macros? It looks more like a copper def to me, as the growth has been slow. Take a look at my grow journal. Update 7 and 8 I did some late trimming and that may have caused an issue?

Macro nutrients. So the nutrients other than NPK. Age old kelp will fix that.

I went back and noticed that my plants looked good up until week 7. Now i can't tell if the yellowing has stopped or if its still going...... sigh. I think i just need a little more time to see if I notice the yellowing stopping.

*not week 7. Update 7 which was week 45 right after the flip to flower.

That's exactly what screwed me up. Lol. I say just relax and give it a few days before trying something else.

chumpkilla, do you have a ppm meter? what is the ppm level you keep your water at most frequently? If you don't have one, it's important to use one in hydro so you know how much fert you're giving. are you using one?
