looks like a cal mag issue and maybe a little nitrogen starved... under LED's you should be feeding cal/mag regular, I do with every feed... I would take off all damaged leaves (you can then judge if you have stopped the diff by keeping an eye on the none damaged leaves), up your cal/mag on your next feed and maybe up your base nutrient by a little... also wait until that pot is easy to lift, you could be causing problems with the pot being maybe a little to wet (but don't let is dry out so the leaves droop)
your PH is good and it's not the RO water for sure
If you find this is persisting then i would take this case to the infirmary for the doc's to give a once over
Good morning, can someone please tell me whats going on with my girls??? I just moved here to a legal medical pot state,
N.M., came from Idaho, YOU GO TO PRISON IF CAUGHT GROWING, any way---Ive got 3 plants in 5 gal. smart pots--ffof soil--RO water with Tags easy feed nutes-- 5ml. per gal cal-mag every 2 to 3 days-- 4by 4 tent with 6in. vortex extraction fan--2 6in. fans and a 6in. scrubber-- water ph to6.5 after nutes-- My girls are 60 days from seed,32 days from flower---This morning, I see brown spots on some leaves---Light on the left is a Platinum 300- on the left is a Roleadro 800 watt COB----
are these autos or photoperiod ? if autos then a little leaf deteriation is to be expected at this stage, the 1/16 pic they look pretty damn good. the cal/ mag amount may also be light.
I use 15ml per gallon every other day, for large plants.
@rick-j I've moved the thread over to the Infirmary Section to hopefully get you some extra help. If you could fill this out to give some extra info
