80F temperature, somethimes more or less...i've watered 5 days ago and today so over watering isn't a prob... maybe the heat stress and the nutes are not strong...

Temp is decent, how many ppms of nutes did you give her ?

Looks like a bit too much nutes as well as overwatering. Overwatering is something that develops over the corse of the plants life. That soil looks soaked to have been watered 5 days ago. Any signs of root aphids or fungus gnats?

you also have what seems to be a ph imbalance

the soil is soaked because i've done a transplant and poured 2L of ph'd whater but didn't checked the whater ph or soil's ph never cause i don't have ph metter. I only add some lemon juice...

I've bought the soil mixed wit the perlit and the ph range is 5-6.5 and i know it should be 6.5-7 but didn't know that time...they have a really slow grow cause the ph imbalance i think and i've planted them in february and they are still in veg...

Yeah I would say the PH is way off, Get some new good soil and transplant as soon as possible. Looks like its very warm in your area, and you have a nutrient lockup problem, Lime can be your best friend with any of the peatmoss mixes that don't have it already

how much lime shoud i put for 1 L of water ?...
untill i'll have my ph metter

Its really hard for me to say as I don't have a base line to go off, or I don't know your water's PH. I use around a teaspoon per gallon in mine if that helps you I'm not sure.

Can you pick up some litmus paper to gauge your PH until your meeter gets here, its fairly cheap.

That's what i'm gonna do but it seems that i can't do that till monday and i've ordered the ph metter 1 month and a half ago...i think that i'll stick with the paper test 4ever... and it's not quite a paper test what i've found ...it's more like a indicator substance and a color schale....it will be fine but till monday i can't do anything...
1 more thing...i've used arround 5 teaspoons per gallon and my tap water have a 7.44 ph (at least that what advertising on the bottle say).Do you think that i have a lower ph than 6.0 considering the soil range is 5-6.5?
