autos in a closet ..help please?

Hi all ive grown in a small space before and it turned out awesome no issues now ive moved the only thing changed is my water...now I have four autos about 4 weeks in...3 seem stunted 1 is producing white hairs already..leaves are lighter green than last time and im worried the 3 with no hairs may have hermied is it likely the 3 are just behind or does the light leaves suggest oh issue? Any ideas

Seems like you might just need to feed them. Did you start with feminized seeds? How are your temps? Can you post a pic?

Ill have to wait to get back to my computerfor a pic ..my phones f'd up..but I did light root stims the after the first week then every other watering I do reg. Grow big and... cal/mag the same as last time minus the root stims...temps are around 75 light on and 59ish off...humidity between 35 and 50ish ...depending on how long since I watered them...they are feminized and im just wondering cause the one that is showing white hairs is doin awesome...the other 3 are less desirable to say the least lol but ill definatly try n get a pic tomorrow for ya thanks in advance for the help.

Are they all the same strain? If not, you might need to use different strength nutrients for each one. I had a La Diva that didn't really need much and now I have Critical Jack that takes a lot more nutrients.

Hi as op said all autos ain't the same. I ruined at least 2 grows, an easyryder got over fed when using same amount of nutes as an affy auto, she really hated nutes and just went bright yellow (making me add MORE nutes tut) and yeah she fucked right up.
Same tale with another side by side i did, i watched one plant bloom and fill out while her groom mate just groaned and moaned her way to harvest. Yeah they'll demand individual attention bro, best listen to them or they'll let you know

Ya I thought about the strain difference 2 are b.f pineapple chunk the other two are auto seeds purple cheese..but what of the other purp. Cheese that is behind the one showing hairs?.. not really sure what's goin on 4th grow and still learning lol. Ill post a pic when I get home from work and see what yall think

Looks to be im just a worry wart lol after today it looks like a few tiny hairs on two of the three...currently working on posting pics ...slow interwebs lol ill def keep yall posted thanks again for the info
