Nute burn. Over watering. And other things...help!!!

[Discretepete2676]

Somewhere I made a mistake... or three along the way and my girls are not looking good. I gave RO water mixed with molasses to them yesterday morning and tonight they still look like this. I've only fed them twice with an RO water mixed with calimagic between those feedings. 26 day old THC bomb autos. Promix HP soil. trio. 600w HPS. Temps are 26-27c and humidity is around 40% since I had to take the humidifier out of my tent recently. Light is a Lil over 24" away from canopy. Any suggestions besides wait it out and feed straight RO water again next time because my soil is obviously hot? I'm a noob and this is my first grow.... My mentor won't see my thread fit a while possibly and I don't want to bother him on a PM. Thanks for all the help and suggestions. Regular pots 3GL with 5 holes in bottom from my local grow shop... Did I miss anything?

Questions

• What is your medium?
• How often are you watering?
• Why'd you take the humidifier out?
• Do you ph your RO water (Some say it's unnecessary but you'd rather be safe than sorry
• How close is the 600w?
• Hows the ventilation?

Off the bat, think about everything you did why they looked good. From what you've said, the only thing different is the humidifier being gone. You're still in veg/pre-flower stage and the humidity must be waaaay higher than that. Some folks get by with low humidity but there pros and use a silica nutrient in their regimen The new growth looks sad/droopy as if its too hot. The leaves can't breathe when the humidity is that low. The rest of the plant is droopy too as if it's overwatered but I'll go on the limb and say the humidity man. I'm no prob with the herb by any means but I grow any vegetable like nobody's business. Hopes this helps..

P.S.
Questions in the beginning are more of a disclaimer because individuals who come by to view your post 9 x out of 10 they will ask the same questions. This is the plant hospital by the way

...straight-up overwatering, mate,... Roots are getting smothered, poor gas exchange! 40% RH is okay, even helpful in getting the plant to try and transpire that excess water away,... Good air movement will also help,...
