I wait untell they show me a sign of needing water, such as drooping or what not. I transplanted them into five gallon buckets so we will see if that makes a difference in the next few days. Is it safe to start to flower them even though some leaves are curling?

TBH They look pretty good, there's nute burn on the leaves below, but its not gonna affect your harvest much. WHat light are you using?

I have them under a 1000 watt hps, but my new set up has a section of the room using flouros for the veg and then they will be put under the 1000 watter for flower. Now I can have a continous supply going. It's my first grow so every little thing I see I worry about, you probably know how it is. So if the lower leaves are nute burn??? then thats probably what caused that curling right?

dude im kinda goin through the same thing, but the yellowing started before i was using nutes, and now that i am its still yellowing, but just on the tips of the leafs, im thinkin it could be as simple as overwatering and underwatering

yellowimg edges and leaf tips are more than likely nute deficiency.I had this same problem on my curent grow.nute deficiency can cause curling yellowing edges ,tips also brown spots on leaves.The pics look like nute lockout to me I would flush them with a mild nutrient/molasses mix and see how they respond.

look i am new but i have done a lot of research. dark green leafs if usually N overdose so if yours are light green then you are fine. curling leaves has a problem with the magnesium or the ph. whats your ph and whats the run off? as far as holes on leaves. do you foliar feed or mist them. if you do raise the lights when you do and lower them when they absorb it. i hope this helps. rememeber optimal ph and runoff, and more N prob but just a bit remember dark green is too much thats what i have but if you just water with good clean ph water they will eventually eat the N up in veg

hey man just looked at the pics you are like me dark green. to much N back off a bit and water straight ph next time they will lighten up. i am lightening up nuts alltogethr from 1400ppm to 1300
