Looks like you have a bunch of N in those baby's?
Did they get a little warm and low on water?

I'm guessing you just need to raise your lights another couple inches and get some more ventilation, just my guess though... :smile:

PH was always a bother when I used a soiless mix.
As a matter of course I always used CalMag per label, it realy seems to reduce alot of those type problems I was having in soiless.

Those are green as hell, might be pushing the limit, I don't see any tip burn though.
Check PH like Chucky said and Lamp Heat.

hi folks,
heres what i do.....i take a gallon of water and let sit overnight
i then check ph...and its always 7.5
i then buffer the water with a teaspoon of white vinegar
brings it down to 6.5-6.8 perfect for me and my plants show no deficiencies

One of my grow books says if they curl upwards, they are praying for Magnesium. I had some like this, same circumstances. Gave them a drink with a little epsom salts, backed lights off a little and one or both seemed to correct it.Good Luck!

hey

hey

hey buddy your problem is going from high humidity ... to low humidity too fast ,, or just having too low of humidity ,,if your humidity is under 40% this could happen ,when soil gets a lil too dry .. i have seen plants do it instantly
comming out of a humidity dome going into low humidity flower room ,,



or just to much nitrogen ,, but ya tips should start to burn first i would think .

i get the saame problem sometimmes and allways thought it was a heat thing but then my 250HPS room doesnt get that hot even in the summer, i always get it in my bubbler so im thinkin its gotta be a ph thing...also is ur root zone gettin very hot and dry??? iv found withh soil if the root zone is gettin hot it has adverse reactions on above ground part of the plant i.e. the leaves bleaching yellow and drying out... :2cents:
