I have 2 plants about week 4-5 into flower which are curling pretty bad. Take a look for yourselves. I’m just a newb so bash away but do provide useful information please.

Oh before anyone asks. Yes they are watered and no they are not overwatered. You do see some yellowing with the curling. PH I’m feeding around 6.0 and runoff is 6.0

They look very nitrogen toxic ( too much) to me....and 6.0 is maybe a little low? Shoot for 6.3 - 6.6
Good luck

Overfeeding. And what strain is that? It's not even forming decent flowers. I'm curious what the genetics are. But that could be from the overfeeding.

Look like possible reveg/ hermie as well? Check for light leaks/environmental stressors.

I do see a curl now that Freddi said that. Maybe back off on the nutes. Try 600 -800

No light leak at all. I checked around for any eight of hermie and can’t find any sacs anywhere.

They did get fed with the lights on but the substrate still remains cool. The plants are nearly 5 feet with the bottom 32” being bare the pots are far from the lights. I have been watering with the lights on for weeks now

What is your temps and Rh ?

Those plants are stressed ... your ppm for flower should be closer to 1100 / 1200 than 600.
Ph should be raised a bit to about 6.5 - 6.7 ( allowing for drift ) . Quantum height is fine ... however that strain has a high leaf to calyx ratio like a landrace . I probably “ would “ have done a pruning of leaf earlier to discourage PM and RH issues.

I would definitely get air moving thru that jungle also.

How much calmag are you adding ?

looking closer at some of the pics you may have to bump amount up ... try 2 tablespoons per gallon for maintenance level amount.
Some of the leaf is showing brown spots... that narrow leaf Sativa plant will run long ( FYI ) some can go 13 weeks plus.
