Anyone see this issue before?
My dad had been growing for awhile now but he is running into this on a few of his plants. He hasn't changed anything from previous successful grows. Water, soil, nutrients is all the same and fresh.
These were started indoors until about two foot tall and planned outdoor. Zone 5B. Watered daily, no water logging off soil. All three were started from seed and all the are different strain. My dad is very experienced with this but I am not. If I left anything important out please let me know and I'll get the info from him.
If he replants outdoors yearly, does he use the same spots ? If so the soil may have become acidic or basic. You check soil pH if it's a repeat grow area. If it's planted in like a field ,there may be other plants competing with or cooperating with the plants
Outdoor? I don't suppose you live somewhere that has been getting a stupid amount of rain lately? It could be nute lockout from soggy roots.
My first thought being an avid gardener of veggies. The soil drains well, definitely not water logged.
Looks like nute burn to me.
Other four plants are on the same regiment without the issue.
Are they the same genetics? Some plants just eat less.
I second this opinion. It looks like the early stages of nutrient burn. It could be as simple as not mixing the nutrient solution enough so the bottom of the barrel is hotter than the top. My first suggestion to every grower is always less is more. I like to use super soil up until flower for that reason specifically, and then just use supplemental nutrients twice weekly until flush. Unless you are growing commercial crops on giant plants or are in a CO2 supplemented environment then it is unlikely the plants are getting large enough to require large amounts of supplementation.
looks like phosphorus deficiency potentially, not all seeds are the same.
what strain?

One blue dream One space candy One cherry pie
All hybrid strains. He also has another space candy that is doing well.
maybe the heat, everyone shaded the same all day?
See my above comment, but I will also say that Cherry Pie is notoriously finicky in my experience. I dumped that strain after two rounds because A: I didn't like the genetic that much and B: it always got locked out while the rest of my plants were going gangbusters. Blue Dream can withstand a nuclear holocaust though. I swear you could piss in the pots and get 2 pounds off a plant.
