Plant problem... top leaves 'drooping', curling downward like 'claws'... help!

Increase ventalation.
Circulate more.
Lower temp.
At that temp your plants have taken up more water than nutes causing the EC to rise leading to salt up.
Get cooler air blowing around. FLUSH FLUSH FLUSH then feed with a MILD nute mix for a week.... 3 day ain't enough.

'Circus' PMSL..Always was always will be.

last two nights temp hasn't gotten past 74 during the light cycle, and down to 63 or so during night. humidity's a bit high... 60%... haven't been able to do much though since there's moisture in the air out.

as far as flushing further i have to see if i can setup a water-only reservoir without too much trouble. if i was to flush for a day or two (in addition to the water they got last night), would it be a good idea to do so with clearex? how much should i use?

flush once, 3-5 times the capacity of your pots (plain ph adjusted water only)........not for a few times . Then use mild nutes for a week.

thats basically what i did last night... it was straight ph adjusted water with a tiny bit of calmag in it (like, 1/4 the recommended amount since i'm using partially tap water anyway that has magnesium and calcium in it). so good to go back to watering i guess then? as expected, the watered down nutrient mix is about 950 ppm.

Wondering what's going on same problem with my leaves they are drooping down!! And it just started today
