Thanks!

You foliar sprayed with an epsom salt solution? I've never once heard of that.

What's the PH of your solution? What EC are you using?

I've been practicing, but I can't read minds over the internet to tell how they are growing their pot.

Umm u havn't? I'm pretty sure I've seen threads on here with people recommending it before, it was just a weak solution..

The PH is 6.5 ish, i don't have an EC meter unfortunately..

What is your heat like at the top of the plant? Maybe even consider nute-burn

epson salts, magnesium-sulfate.... definatly wouldnt folular spray,is typicaly used in agraculture/horticulture too lower ph levels in growin mediums or water resevoirs, watr u growing in,clay ball's?? or a coir-soil mix, u need a ec pen m8!!i rekon,recomend rather,can get them on ebay for buger all,chepper thn th hdro shops!! :-) your ph mite be fine ;-) but ill bet, your ec is alittle high(spray solution) ph test and ec your feed mix and resevoir....

this is an intersting read toooo

Im still learning here but I wouldnt ever do that. I do use it to flush my medium (soil) out though. I use 1 tsp Epsom salt + 1 cap full of Perocyde to 1 gallon of water. Works well.

what's your humidity? i had similar problems due to low humidity, black leave tips curling up

Thanks for all the replies!!

Yeah im gunna get an EC meter soon, my temps at the top of the plants are aprox 73-80F, humidity 40-50%.. im in week 5 of flowering.

Yeah it was only a weak foliar spray solution with some epsom salts, warm water. I figured seeing as its only a mild leaf defect a foliar spray would work.

I've fed with iron/mg/cal tonic thru a flush/water and it's brought the green back a little on them all but this one just has the leaves curling up thats all, which was weird to me seeing as iv given them plentifil magnesium n stuff, maybe too much? Should i just flush next time i water this girl?

And my medium is a mix of compost, light fluffy soiless mix and pearlite, sorry i cant be more specific but the soil brand is cellmax, and im also using the cellmax organic nutes, grow bloom, pk booster etc

Foliar sprays, in my opinion, are a complete waste of time. That's not what leaves are for. There's roots to pick up what the plant needs to grow.

Um thanks? but I think I was already aware of your opinion.
