First time grower here Having some problem with my plants, I can answer any questions you need to know feel free to ask but any help would be greatly appreciated. Room temp is around 77 degrees, humidity between 50 - 60 running the entire heavy 16 line with fish shit

The look over watered. What soil and how often do you water.

 

[XcoopX]

We water about every 2 - 3 days depending on weight of the pots - running promix HP

Those look like 3 gallon pots. Is that right? That means they need at least a 5-6 quarts each watering. A 6 quarts of water weighs 12.5 pounds. How much weight are they losing before you water?

using 15 gallon pots and usually giving them 2 gallons a plant

I am assuming you water till runoff. If so then they are severely over watered. You probably have severe root damage as a result. I would raise the lights alot and stop watering until the pot loses about 35 Lbs. Maybe she can still be saved.

We don’t water until run off - usually never is any runoff- we let the plants dry out prior to watering they almost felt like a lb or 2 at most, super light honestly we thought it was overwatering so we let them dry out Pretty good I was just making sure - is there an appropriate amount of water we should do per 15 gal pot of water? Thanks

Pot of soil not water lol

I would say overwatering or possibly a nitrogen toxicity... do the leaves feel thick and heavy? If so then its probably overwatering

Without runoff, how do you know the ppm of nutrient in the rootzone?

I think you have likely got a case of over/underwatering, and by that I mean watering too frequently with not enough nutrient solution per irrigation. You probably have a major nutrient buildup in the media, ph is probably real low too. Next time you water, run nutrient solution of 0.8ec/400ppm at 6.5 ph through it, and use enough to get good runoff, then see what comes out the bottom. Test that runoff and get back to us.

Also... way too many bottles man. When you do the rinse to determine runoff ppm just use the base nutrients. Veg A and Veg B I believe it is. That's really all you should be using out of that lineup anyway tbh. Although I havent looked at each bottle to see what they all are. lol, Its just too many.
You do have a ppm and ph meter I hope?

It looks like a watering issue as well. What's the PH of the runoff?

Verticillium? Hydrogen peroxide will add some oxygen to the roots.

1 gallon of water weighs 8.33 lbs. My three gallon bags require almost 1.5 gallons to soak to runoff. That's 12.5 lbs of water every three days. IMO your containers are to big. If you don't water them all the way, how do you know there's no dry spots? 15 gallon container probably would take 7 gallons or more to saturate. That's almost 60lbs of water. The large container would be too wet for too long and invite to many unwanted pests.

Hey xcoopx ,have your stems been that color " dark purple " for a while ? Your plants are severley stressed , you've done a lot of training ? How tall are they , when do you plan on going into flower , you are going to have to get them back on track before you make the next move , or you might end up seriously dissapointed....

What kind of light ? Grow medium ? And whats the entire line ?
Plus fish emulsion ? You migjt have overdone it with additives...
Seed ? Clones ? Just curious
