Plants dying in flower

[Peppie]

Hey I'm new and need help. This is my 2nd grow. The 1st were autoflower and came out ok. This grow is regular plants. 2 GSC and 2 sour patch kiss. 1st off the GSC have been growing since January the sour patch kiss since March 7th. They grew real slow and now we are in the 3rd week of flowering and the leaves are dying. The nodes on the GSC are too close together on top of each other. The soil takes 5 to 7 days to dry out.

I'm an outdoor grower so I can't be much help but there are folks here who can but they'll need more info.

What are you growing in, the medium, potting soil?

How large are the pots they're in?

Light. Type, wattage, hours per day?

Water, Tap? Bottled?

Fertilizer. Brand name, how often?

Write all this up in a response and anything else you can think of that would help and you'll find some answers.

Welcome to the farm.

Fox farm ocean forest. 3 gallon smart pots, 1000 watt Led by lonwon. 4 x4 tent size 6ft tall. I use the fox farm dirty dozen. Dechlorinated tap water . Feed according to fox farm feeding schedule. Inline fans by AC infinity exhaust as well.
Since they in flower the light schedule is 12/12. It was 18/ during veg.

It is almost impossible to tell, but your plants might be overfertilized, following a feeding schedule is not always a good thing, especially not when you use a soil that is heavy in fertilizer

 

[Peppie]

Thank you I kinda figured that. I already flushed with regular ph water at 6.4.
For the remaining weeks I will only use half the recommended dose for Tiger Bloom and Big Bloom. Any recommendations?

Might help to have some more pics in normal light

I think you are seing the #1 reason for problems, overdosing on nutrients. Fox Farms soils are pretty hot. I've said this a hundred times. When you pour more nutrients into an already pre-charged soil, you can not only overfeed them greatly, but also screw up the Ph and stuff because the soil is full of everything needed, and additions can raise or lower the Ph, causing all kinds of issues. I always maintain that it is a LOT easier to add nutrients than to get them out. Flushing might help, but since the soil is chock full of nutrients, flushing might not help as much. I would give it a try, and go easy on the nutrients. If it is taking your soil 5-7 days to need watering again, you might want to add some perlite to the mix to allow for better draining. Promix is great if you can get it, as it really can eliminate the overwatering issues.

In my opinion it's always better to underfertilize a little than it is to risk overfertalizing, have a little less nutrients wont kill the plant but too much might, and the loss in yield is insignifigant but the taste is a lot better

@Peppie, second that request for natural light shots...I’m not seeing anything in the first shot for alarm, at three weeks into bloom.

I agree. I based my earlier reply on what looked to me like twisted leaves in the purple picture, but perhaps in regular light it looks differently. I still maintain that less is better for growing.

I have a water meter and only water when it says dry. Also they have perlite at the home depot in my area. I will try that. I also have 2 Sour Patch kiss that are being fed the same regimen, so being new I'm confused as to why the GSC did what it is and not the others. Can they be saved?

The leaves are twisted and stacked on top of each other. The leaves are turning brown on me.

I think they will be OK if you give them a flush and go easy on the feedbag. There are so many cross breeds and mixed strains anymore that it is getting impossible to dealing with the particular's each strain has. Some strains are more sensitive to excess nutrients than others, much like some strains are more appealing to bugs than others. Most growers are using the maximum amount of nutes that they can without overdosing them, and the line is pretty thin when it comes to overfeeding and feeding the max that you can without problems. During later flowering, many strains will lose many or all of their fan leaves, with Sativa's seeming to be more likely to do so. If this doesn't happen, it usually means there is still a lot of nutrients present in the growing medium, although a flush might not remove them.

Thank you that helps a lot. I did flush last watering so I will go light on the nutes

Not sure what your prob is but its not overferting,Ive had plants that looked exactly like yours. I treat with VF-11 and within a week they were thriving,I use it as foliar and in soil. It fixes sick plants and makes healthy plants thrive,been using for 30+ years

Looks like pH issues to me. 6.4 is a little low for soil, in my experience esp. Foxfarm soil, 6.8 to 7.3 is the normal threshold. I don't use RO water, though, and never have/will, so my experience may differ.

Checking my eyes, none of those recent pics seem in focus...

The soil is 7 for ph. I'm sorry I confused you. The water I flushed with was 6.4

I also only use tap water that has sat out 24 hours or more
