Problem: My leaves are curling up and the stalk is turning purple. Any ideas?
judging by ur past post in different threads i am going to say ur room is hot. Also looks like u may have a ph problem. This far along i would start flushing with a salt remover. water with plain ph water. It looks as if they may be p burnt or p locked out but we need more info to go on.
good ? but giving us more info would help us diagnosis. what ur water ph ? whats ur run off ph on a good one ? what the run off ph of a bad one ? what medium are u using ? what nutes ? to many things can cause this kinda reaction
From the photo it looks like the fan is too close and how deep is the soil that your plants are growing in. I see you say pot size is 5 gallons but pict looks shallower. Also how close are the lights. Do you ever just use water w/out nutrients?
I guess that is 80 to 86 f
ok at 80 at 86 you may be evaporating the water off
you may want to raise the lights while they heal.
Do you feed them every time you water?
you may have salt built up and need to flush
then feed 1/2 strength.
look up the lift pot method of watering at first glance they look thirsty.
I run my ph a little lower 5.8 to 6. Check you runoff ph.
I'm still new at this, I hope an expert looks in soon for you
yes i feed them with nutrients every time i water them with sensi bloom, at full strength. Now i have flushed them with 6.3 ph water. 10x for now if you have something else new in mind for me pls send me back ... cause i'm open for any suggestions. keep on high !!
I don't normally grow with soil (I'm a hydro guy), but with the info you have provided and what little knowledge I have of soil growing, I would venture to say that you over-ferted them. I thought you were only suppose to feed them every 3 waterings? Again I am not an expert on this technique. Hopefully an expert can provide some better insight than I.
