I agree with @mysticepipedon. Prob locked out P and should cut back on the cal/mag. Check PH and if to low flush. Just some other useful information …. Recharge is a great product for soil health. Dolomite lime as a top dressing can help a low soil PH. I dropped fox farm nutrients and started using roots organic HPK rather than tiger bloom. The fox farm nutrients highly depend on flushing routinely. Make sure you have good airflow to your roots and add more drainage to make sure your getting adequate run off to avoid salt buildup in the root zone.Looks like a phosphorus deficiency or lockout.
What's the pH? If it's below 6, raise it to between 6 and 6.5.
You might want to boost P and cut back a little on cal/mag, which can interfere with P uptake.
Recently, I boosted P too much in flower and caused K lockout, so avoid overkill.
Have you flushed at all? Yes i flushed 3 weeks ago, since i watered them yesterday (sat) im planning to flush again on tuesday.
And it looks like your temp dropped to 59F? Wouldn’t let it get that cold and temp should only shift 5 degrees from lights on to off. i thought it would be ok, :/
Would elevate your pots so they get good air flow. ok, i will elevate my pots, trying think what could i use?
I know with the fox farm lineup they recommend flushing to mitigate the salt buildup with the grow big and tiger fox. I had a similar thing happen and think it was due to locking out the soil. Not 100% positive and would wait for some pros to chime in on but I would make sure to flush and feed at 1/4 of the recommended feeding. i think i will stop using foxfarm products, once i finish them.. any recommendations appreciated.

Since i bought the starter package, it came with all below, maybe i need to cut back calmag and flush them
+ i was following fox farms recommended dosage, probably i should cut that in half too..
Best temps are 76 during lights on and 60 at lights off. This is the magic zone for growing weed.Have you flushed at all? And it looks like your temp dropped to 59F?

Elevating pots - I put golf balls under my pot in the tray. Had multiple folks recommend this along with additional drainage holes to avoid root rot due to poor drainage along with assuring roots get oxygen.

Always learning something from the pro @ComfortablyNumb. Didn’t realize 60F was the desired temp at lights off.Best temps are 76 during lights on and 60 at lights off. This is the magic zone for growing weed.
Looks like you are having pH issues that is slowing mag uptake. Run a slurry test.
Slurry Test
Soil Ph Slurry Test - Step By Step With Photos
Knowing the pH of your growing medium is important from time to time. The soil pH slurry test is the easiest way of finding the true pH level of your soil based growing medium. For this you'll need: pH Meter - Cheap Amazon pH Pen - Blue Lab pH Pen - Blue Lab Soil pH Pen Cup or Container -...www.thcfarmer.com
It mimics the cool fall evenings and causes the plant to pump out more trichs and change to harvest colors.Elevating pots - I put golf balls under my pot in the tray.

PH - Assuming you have a ph pen/meter. If you do google soil slurry test and do one to make sure your soil is at the correct PH. Your water could be at the correct ph but salts could be building up resulting in low PH and nutrient lockout

resetted my thermometer, yesterday reading was min 59- max 65, will try to increase thatBest temps are 76 during lights on and 60 at lights off. This is the magic zone for growing weed.

What are you growing in?resetted my thermometer, yesterday reading was min 59- max 65, will try to increase that
Slurry test results: PH 6.3 / ppm 722-733nutrient lockout?
if i need to flush, should i wait until plant gets dry?
