Plants look a bit sad: any ideas?

[Charlie Newsum]

I have a feeling I have over nuted.
This is end of week 4 .
In coco.
Water a couple times a week with grow research.
Under cali light works 2 x 550 solar systems.
And input would be good.

Very dark and curling. Looks like your K is a little high.

What are you nutes, pH, and feeding schedule over the last week?

Dark green and clawing leafs indicate Nitrogen toxicity. I’m dealing with it myself.

I feed Mega Crop and bumped it a bit too high over the past week, so I ran a quick rinse through my soil, and dialed it back down.

What week are those in?

What week are those in?

I flipped on March 2. Week 5, but I start counting once I see flowers forming.
This was March 11. They are all different strains, but all started forming the same week.

I run ph 5.8. Grow research nutes. Water a couple times a week

5.8-6.0 is good, but with Coco, you need to water/feed daily using 1/4 strength nutes until runnoff.
I grow in soil, but this is pretty standard for coco. You basically treat it as hydro.

If i water every day until it runs off they would never be dry? And isn't that fucked?

These are the others that don’t have the same issue.

Let me pull @Chris Scorpio in.
Coco is completely different than soil.

If i saturate my pots they aren't dry for like 4 5 days

 

[AdaminCO]

What brand are you using?

 

[Nunyabiz]

You never want coco to dry out, should remain moist.

Coco

At a guess I’d say the nitrogen is way to high for flower .... next water flush her with clean water/no Nutes and let her use the nitrogen in the leaves. Water a couple times with just water. What npk are you feeding her?

 

[SarahJane211]

In coco.

Coco .............
Water every day with 1/4 nutes, in flower add more P + K, maybe reduce the N a bit.
I'm a bit lazy and sometimes water every other day.

Grow Research nutes seem a tad expensive at $40/Kg.
I'm using Wesco 20-10-30 +TE ($5/kg) for veg, then adding Wesco 0-52-34 ($5/Kg) as well for bloom.
Why pay more?

 

[shottafire]

Definitely over did it with the nutrients but you can save these. You really need to drop the ec inside that pot and by watering 1/4 strength daily it will get you there. Coco is opposite of soil in regards to watering. Never feed plain water to try and flush coco this will only create more unwanted symptoms. just consistent low strength feeds.

 

[MarioUK]

Too much N. This is nitrogen toxicity

 

[AdaminCO]

Yeah we’ve gotten the nitrogen part... now we just need to get his feed schedule and ratios down.

They’ve been treating it like soil, but had been going in at the correct pH. (5.8-6.0)

I’m waiting for the brand of coco... just to be sure what they’re working with.
