Better pics this time.

[Murphybarnes]

Just starting week 4 since flip. All Bio Bizz. Soil plus Grow and Bloom. Mostly Bloom now. 250 watt HPS about a foot and half above canopy. Watered twice weekly with about a litre and a half each time in a 20 litre Airpot. Nutes every other watering with about 2 mil or so every litre.
The second pic is interesting. Not come across this before. Still not come across the definitive answer to whether I should bother to ph if using soil and organic nutes.
Help appreciated. Cheers.

The first picture looks like not enough nutrients (leaves are turning yellow) and the second picture I'm not so sure about

 

[harrychilds]

are the leaves in the first picture from the plant in picture two? If so, then up your nutrients because you have a nutrient deficiency

 

[catdaddy516]

Looks like potassium deficiency. I've had that before from water logging the medium.

 

[Murphybarnes]

Same plant. I tend to get yellow tips and very occasionally burnt tips so I tend to dial back from overdoing the nutes.

Well those leaves are definitely telling me you're not feeding them enough, the plant is literally sucking the nutrients out of those leaves and feeding it to the main plant to stay alive.

You have it
Too many nutrients for a 250 watt light

I'm not sure I understand. Too many nutes for 250 watt light.

If you are using a nutrient schedule it is too high

Plants absorb smaller quantities of nutes at lower light intensity...

Crispy burnt. Everyone’s saying under fed? We’re seeing the crispy part right? Pic1 vs pic2? Same plant? If so. I’m going with overfed and possible ph problem as well. (Which usually goes hand and hand)

 

[Murphybarnes]

My light is dimmable. 400 watt is possible just have a heat issue. In a cupboard with no exhaust, just the odd fan now and again. Lots of height though. 10ft.

 

[GanjaJack]

Well that's' one way to kill a plant.

Think of the light as an engine and nutes are the fuel. A civic doesn’t drink it like a dragster

 

[Murphybarnes]

So what's the concensus. Underfed? Over? Light?
Just interested. My plants whilst never perfect always make it through, just trying to glean some info along the way.

 

[DrOgkush]

In my head. It’s looks over fed and burned from over nutrition. I also see what “looks” like water splash on the leaves in pic 2.
But I don’t know everything your doing.

if you can’t get a clean harvest with what your doing. I’ll suggest the same thing I always do (what I do when things get tough) Good pre mix soil. Seeding starting mix. Minor dry amendments. (EWC for starters, low dosage dr earth) and tap water. Water when needed and keep and an eye out till harvest.
It’s like a reset button for me.

Only see one person who said “under fed”
The op seems confused because of one differing opinion

I'm just curious, have you ever checked the PH of your nutrient solution after adding the bio bizz? Typically you don't need to check PH in soil, that's true, but Bio Bizz is notoriously acidic, so depending on your source water, you could be feeding an extremely low PH.

That’s why I posted my personal opinion on what I feel and what I’d do. I didn want confuse op anymore….

And I count 2. I thought more because one person posted multiple times.

Yeah when I add my bio bizz nutes it takes the water from pH 7.4 down to like 5.4. Once I add some benificials and let it bubble for a few hours it comes back up to like 6-6.2. So Im assuming that it would do the same thing in the soil. Ive ran bio bizz for years now and have always pH'ed my water. However this time I havent been because im always being told not to and so far so good. But the 5.4 pH def sketches me out.
