Cant figure out what is wrong with my plants

[Dilan R Wertz]

I have something going on that has continued to get worse and worse. I have 2 WW fem grown from seed that are about 7 weeks or so old. Maybe a little older. They are in fox farm ocean forest in 5 gallon pots. Just transplanted from 2.5 gallon pots. They are under a 1000w led now but where under 400w mh up until about 2 weeks ago. I started feed with the fox farm trio about 3 weeks ago so ive only fed 3 times. 1/4 strength the first 2 times and then half strength this last time which was last night. I use cal mag in every watering 3ml a gallon, I'm using distilled water. PH the water to about 6.5-6.8 every time. This has just continued to get worse and I cant figure out what's wrong. The PH is good. Temps are mid 70s with light on and high 60s to low 70s with it off. 40-50% humidity. I have a 6 inch fan taking air out of the tent thru a carbon filter. Any help would be appreciated as I would like to bring these back and not let them get much worse. Thanks in advance

Ffof is pretty hot. You should wait till they look hungry before you start feeding.
Underfeeding is easily corrected, overfeeding burns and stunts.

This all began before I started feeding. I began feeding once seeing some issues arise and it hasnt gotten any better

Overwatering symptoms look the same as pretty much every excess and deficiency.
You definately have a problem, but ffof has been shown to be a pretty reliable mediium all by it self.
I would guess its either environmental, or a watering issue

You burned the shit out of them. I use the FF trio as well. The Big Bloom has never given me any issues but the Grow Big in combination with CalMag, at least the Sensi calmag I used, will cause burn. I stopped using Grow Big so I could give calmag without burns.

I water evey 3 to 4 days so I dont think it's that. But I dont know. I've never had these issues during veg. It always starts midway through flower when I start seeing issues

Well I let them grow for probably 4 weeks in the ffof with no nutes just cal mag. Then started feeding once some issues started coming up. But they were fine for weeks in that soil not burning or anything. Then out of nowhere it started. So it's not burn or it would have been burnt as soon as I transplanted into that soil when it was young like 2 weeks old

I think the soil was right at the limit and when you went from quarter strength to half strength it was the straw that broke the camel's back. That's just my 2 cents.

I just gave half strength last night and that's the only time. So it hasn't done all that since last night.

When you transplanted did you use new soil? If you did, the plant had all the food it needed with the new soil. Adding the extra nutes on top of the fresh soil is more then likely the problem here.

I use my calmag with my waterings instead of adding it with my FF nutes too.

So you use the cal mag on the watering between the nute cycle? Even though using distilled water? And I just transplanted about 2-3 days ago. Yea using fresh soil. But I just watered with the nutes last night. So I may see some problem from that later but obviously something else is going on

Bro I'm just trying to save you time and effort here. That new soil was like feeding nutes in and of itself then you fed again when you went to half strength. I'm not trying to hate or send you in another direction from being uninformed.

Right but this has been happening for weeks bro. That can't be the cause of it because I just transplanted a couple days ago. Yet this problem has been going on for a couple weeks. Slowly getting worse.

Were you feeding prior to the transplant?

 

[Dilan R Wertz]

Were you feeding prior to the transplant?

2 times, 1/4 strength and it was still getting worse. Then transplanted.

 

[TheSadVeryBadMadGrower]

If the soil was fresh prior to the transplant, the nutrients that you were feeding was doing that to your plants. Fox Farm has everything you need in it for a good 3-4 weeks without needing to add any nutrients. The extra nutrients you were adding were frying your plants.

 

[TheSadVeryBadMadGrower]

You just transplanted recently, so don't add any of their nutrients for the next couple weeks. Just water. The new soil has everything she needs for a bit.

It was in that soil for longer than 4 weeks or right at it. That's when started feeding the nutes. I've grown with ffof before so I know it's good for a few weeks just by itself

Don't get defensive...they may have been right at maximum nutrients (from soil) when you started feeding them. Sure looks like nutrient burn to me.
