First time Grower...Leaves are curling

Hey there guys, so im a first time grower and I picked up 2 OG clones exactly two weeks from today. All I have done is have them under 24 hr light and potted them in 7 gal pots once the roots grew out of their rock-wool cubes. Last night the plants looked a little droopy so I gave them a little water and they came back up but recently ive been noticing the leaves are curling and I noticed brown spots on some leaves. I have them in FFOF soil. I tested the Ph levels and they are 6.03 in one plant and the other one was 5.97. I tested the water I use and it tested 7. I havent given them any additional nutes other than in the soil already.

Having the same curling problem but my leaves are dark green and curling up. I am pretty sure it is a copper defiency.

i would change the soil. at least what you can and get some of the nutes out of the dirt. u could have shocked it going from one environment into your environment. ive never heard of a copper defiency but i have heard of mg defiency but yeah u are probably stressing it from changing the environment and nutes

Give them a few hours of darkness...

Plants produce certain carbs only at night....and they need these to grow healthy and strong.

Should I switch to 18/6 now?

ya dont do 24 hours of light. there is a good chance that it is just transplant shock. make sure you are not over or under watering and it should bounce back

Ok when you water. Ur not supposed to water them until water comes out of the drain holes right? That's if I'm flushing correct?

did u have a humidity dome on them while they were rooting? is so they need to be weened off the humidity instead of going cold turkey

I'm sorry I don't understand. Don't know what a humidity dome is? Can u please explain?

a humidity dome is anything you can put over your plant to creat a greenhouse effect like a thrash bag but i think you might be watering too much

I only watered when the soil is really dry. I pour bottled water in a one gallon jar and after watering both plants I have about 3/8 water left. Is that too much or too little? I have them in 5 gal and 7 gal pots filled 1 inch to the top.

From my understanding, you SHOULD water the pots till they drain out....u want even the bottom of soil to get moisture so that the roots look for the water and branch out......gotta make sure you got good drainage though or else u can have water trapped and it'll create mold...

after 6 hours of darkness they arent curling anymore but they are drooping pretty bad. I havent watered since yesterday morning and its been really hot the past two days and its been 86F inside my grow box . Could it be nute burn from watering the soil. since the soil is time release.
