@N0fun, ah yes, PK is Phospor and potassium from the NPK. NPK is the nutrients you're giving it, usually on the label they'll tell you what's inside like this NPK 4-2-2 (veg) or 2-4-4 (flower), a PK boost is NPK 0-4-4 something like that ... the numbers are less important than the ratio . http://www.canna-uk.com/pk_13_14 i dont sell this stuff but i use it lol ... so you just add this to your regular feed, you shouldnt need to change anything. (if you do, add some cal mag, it's late but you need it kinda - never grow without it from now on) sounds complicated , but it's very simple, hope this helps ! 🚀

@CRiSPrGrow, Thank you very much .. this is very helpful. I have just a noob question : How i should add some PK ? what is the preferred method at this point?

I took a look on a lot of diaries and.. she seems pretty big for 18 days no ?

OK so my plan is : Tonight i'll water it ( i did it last time Saturday afternoon) i'll put 400 ML water with .5ml of bio-grow. ( Thanks Mrs_larimar ) I'll also rise my light to 20 inch this is about 10 atm.( thanks ExperimentGreen and Larimar) i'll also change my light schedule from always ON to 20/4 ( thanks ExperimentGreen) i am still thinking about re-pot her in a bigger one ( 4GAL )

Ive ben looking through the diary and the girl looks nearly crispy... rise te light, give her more humidity... . She grows dense , with a short internodial distance " sehs dwarfing" under the light

Atm she dont look to bad. But in my eyes very dry. She can droop beeing to dry to. So dont worry, nothing bad happened. Its ways better to give less water than to much, ( smae with nutrients). try to install awatering regime, in your plant routine. You will see she develops nicely. If possible give her ahumidifier, because hemp loves to have te right humidity for the average tmperature http://www.just4growers.com/media/23631/vpd_2degree.gif here you can see wich humidity you should achieve in dependece of growstage and tmperature

I think bringing in the bio grow is a good idea, starting small like you say. If you're using the fabric pots try putting a small fan around and you could probably water safely every 2-3 days. Also...how i mentioned the light, this is just personal opinion but maybe the plants might benefit from a little rest period of dark hours instead of the 24...maybe 20/4?

Wow thanks guys you are awesome, i like this website. ill for sure do what you are telling. My main concern is : My pot is to small.. this is a 2 GAL / 4 Litters and i was planning to keep this one. i read , on Auto seeds must be planted in their final pot.. is that right? what do you recommend a 4 GAL / 8 litters ? i am afraid to change the pot now.. she seems weak
