these spots started appearing on my plant, seem to start at lower part of plant and has made its way to the top. Wanted to check with others before I took steps to correct, and also has anyone ever seen fan leaves that just seem to lay flat, like they have been overwatered. No matter what I do the fan leaves of 2 others plants don't wanna perk up. The other leaves seem fine. Last pic is the plant I'm talking about. There looking pretty sad. I let them dry out and just did a feed this morning so I'm lost

This is a paste:
The more information you give the better the help you will get.
How large are your pots?
What medium?
How often do you water and how much water do you use?
What nutrients?
How were the nutrients used or mixed, how often were nutes used between just using water, how much of each nutrient was used?
What temps and humidity?
Do you have fans for air circulation?
Stuff like that and other info will help.

Well I figured the pictures would say everything but I'm growing in 5 gal pots. Started in 1 then 3 then 5. Using flora nova nutes. Might of starved them a little a couple weeks ago. But after a feed the plant with the spots peeked up but that's when I started seeing all the spots. I've been phing water at 6.0. Thinking of raising to 6.2-6.3.! Temps during the day 79, night 70. Humidity around 42%. Now all the plants are showing purple in the stems. 2 are cheese strain. The other is a granddaddy purple kush so probably normal for that 1. Actually on that 1 in the last day or 2 about 2 inches above the base of the stall has turned a dark purple, almost like a bruise color. Fed back to back feeding of 2.5 ml grow because i starved them I believe

These questions are important.
The medium is important. What medium?
How much water you give them each time you water is very important. How much?
You are starting to generate interest. Answer these questions.

Ok you seem like you are experienced, I have one ak-48 and one Agfan gold.
Ffof soil. They are four weeks old.
250 watt air cooled mh I have a small fan blowing on plants. 20-25 Celsius from day and night. 40% humidity. Haven't fed nutes yet. What is wrong with them?

Best to start a new thread and fill in as much info as you can about the plant with pictures.

Besides everything else thats been said I would check with jewelers loupe and see if you have bugs. Usually first thing I do when I see any type of dotting

You are starving them. Ditch the FloraNova Grow and just use the Bloom at 8 ml per gallon - it's the Lucas Formula.

The two on the left are way overwatered... the the soil dry out more between feedings. Dots are likely cal deficiency, like you suspect. Purple petioles are mag deficiency. But as dankskank said, they need more than calmag... put them on calmag, plus your floranova grow. If you wanted to add something to give them some help... try a kelp supplement like Liquid Karma.

So just use bloom through veg. I think I saw that somewhere else. I'll check around be for what amounts to feed at seedling and up. Thanks for the input. I am growing in promix hp. Sorry I left that out. Today the first plant is looking better, the pestioles are straight up at the light like I like, lol, the back left is about the same, sad looking, and the back right 1 is also perked up. The sad 1 still isn't showing any signs of defiencies. Maybe slight yellow showing up on bottom leafs, but not much. Never seen plants so up and down. Guess there paying me back for starving them

A little update with some pics. I haven't really done anything yet except leave my tent open a little bit and 2 of the 3 perked up. The 1 that's not is getting a little dry but the soil is still slightly damp. Added another picture of a bottom leaf of the first plant. Was wondering if maybe air exchange could have been affecting them slightly. I left tent open for awhile they were those same 2 were perked up. I closed it and came back a few hours later and they were sad again. I accidentally left it open last night in a closed bedroom and there perked up again today. I have a 200 chance inline fan blowing cold air in the tent constantly. I have a 6 inch inline fan sucking air out through scrubber which I had on low. I've never had that so low so I turned that back up. I'm gonna leave the tent open and see what happens. Just gotta get these defiencies fixed

just looks like bad mag deficiency, give em a tsp of epsom salts the next few times you water, see if that doesn't stop it

and air flow/temps can definitely effect plants a lot, it sure seems like your tent is too hot with the door shut if they're drooping when you shut it up and perk up when you open it. if its not making your house stink, leave the door zipped down.

I have sprayed them with Epson salt before but not in the water. The tent does not get very hot when it's closed up. I have a portable air conditioner with the small in-line fan blowing cold air directly in so at the canopy of the plants the bow 79 at the base of the plant it's about 72 or 73
