Hey all, at my wits end with trying to figure out what is wrong with my ladies any help or advice would be massively appreciated

Im running Athena nutrients, two feeds a day in 3 gallon pots with 10-15% run off. Using Coco perlite mix 70/30

Ph is 6~ and 3 EC (as per Athena guidelines) while run off is coming out at 3.5-4.2 EC and ph is 5.7-6

LED lights are roughly a foot above the canopy

It started with the tips of the fan leaves going yellow and turning upwards and slowly progressing throughout the rest of the leaf. My environment is about spot on (I think) 25 degrees Celsius/ 77 F, with the humidity at 51~

They are at the start of week 3 and the yellowing is progressively getting worse

Cheers

Waaaaay to strong sauce. Its better to add another feeding than increasing nutrient strength growing in soilless.

25C and 51%RH is acceptable but far from spot on.

I suggest stop following nutrient manufacturers recommendations and instead follow recommendations for growing Cannabis. They only want you to use excess for profit.

I feed at the most 600ppm / 1.2 EC in full flower and that's feeding up to six times a day under 12/12. Growing in Coco coir.

What would you suggest the temp and RH be at in early bloom?

The Athena pro line mix recommends 3.0 EC the whole way throughout bloom. Next move to 1/2 the dilution you think?

I would run 1/2 solution until your runoff ec comes back in line. Then slowly increase till ec is slightly lower or stays the same in runoff.
I run Jacks and they recommend a 2.4ec in flower which is too high for my conditions...I run 2.2 and runoff comes back about the same.
