Hi All

I'm having nitrogen deficiency (I think) & I'm wondering should I worry? I know it can happen during veg & late flowering, but some leaves near the top are starting to loose colour & its only Day 24 of flowering.

I fed them yesterday with 3ml of Biobizz Grow & then gave her another 2ml of Biobizz Grow today: NPK 4.0 3.0 6.0

Any & all help would be appreciated.

Thanks for replying!
Im using a liquid ph tester, so I ph my water. I always have to use PH UP. I get it to about 5-6 (according to the PH chart) & I tested the run off yesterday & it was the exact same.

If you are in soil, that ph is way low.
5.0-5.5 is too low even for hydro.

I don't see pest chewing, I see ph destruction.

Yea. Soil has buffering capabilities, but 5 is way to acidic. It's locking out your nutrition.

Hey, I really appreciate your advice. On the next feed I'll up the ph.

Again, Thanks for taking the time to help!!

Don't worry about the like lol. I made a thread in the newbie section about it.

Yea, up the ph without overwatering. I stress that because you will do really bad damage if you overwater it, even with the right ph.

A ph pen is much easier by the way. Just a thought.

I know. But I was doing my first grow as cheap as possible. And reading whats best for newbies, Biobizz seemed the best option. I plan to do a DWC for my next grow, so I'll def have to get a good PH & EC tester

Nothing wrong with biobizz. Ph meters are fairly cheap. 10$-15$ for the yellow ones which averaged 2 grows for me. They are much easier than matching colors, especially if color blind lol.

As noted above, if you're growing in soil your pH should be higher for starters, although, Nitrogen is your easiest element for the plant to acquire at multiple pH ranges. Can you provide a pic of the full plant under regular light?

If she is indeed N deficient, your feeding of the Grow nutrients, along with time, should show pretty immediate results in greening up your plant. If greening up is not the result; you have other issues to consider.

Let's see a pic if you can; it may shed more light on the subject.

Thanks for taking the time to reply. There is a clear picture at the start of this thread.
Im using Biobizz soil & nutes & I gave her an extra 1.5ml of Grow last Monday trying to fix it. I recently found out on another forum that you dont need to ph your feed as Biobizz sorts it out itself. I was told this is why Im having nutrient lockout. I flushed today with 2liters of water & I'll see if that works.

Again, I really appreciate you taking the time to help!
