Looks like nitrogen deficiency to me.

Jimmy Luffnan · Apr 15, 2013

The spots on the leaf in the 2nd pic look a little mid stage potassium deficiency too.
Nitrogen and Potassium deficiency.
How is the PH?

Cheers Jimmy.

yeah i dont think its nitrogen looks more like potassium. the bottom leaves would be turning entirely lime green to yellow if it was nitrogen usually. id hit it with some bloom type nutes or something with more p than n and some cal mag to be sure. bloom nutes have zync in them also so if it was that also it would fix that.

Thanks for advice. Now I have some bloom nutes Big Bud, Bud Candy And Sensi Bloom A+B. I am going to search these products which have more potassium. But I think a little bit sensi bloom solve my problem. I am going to tell result when I do.

Peace..

how close are the lights, can you hold your hand under there at plant level and not have your hand get hot?

zzwasted · Apr 15, 2013

looks like cal def but im not a pro ..

MYOB · Apr 15, 2013

Not a deficiency. Heat/intensity stress.

If you are feeding your plant, most likely its not a deficiency. Its more likely a buildup of salts causing lockout. Adding more fertilizer just compounds the problem. But thats not even it here. It is affecting the top leaves only, you just dramatically increased the light intensity and the humidity dropped 10%.... doesn't take a master.

and that looks nothing like a nitrogen deficiency.

MYOB · Apr 15, 2013

or a calcium deficiency.

and before anyone says it...not an Mg deficiency.

2.5 Hand Span and it is not hot at plant level also I have a cooltube it helps. But before hps ,3x 150w CFLs were too close my plants like 5-7 cm again not hot again.

Do you think I am not searching. If you want I can upload my browser history

But everybody says different things you can also see in this topic too like Heat stress, overnuted, cal,mg,N,K deficincy. I am Amateur man. I need to learn it with first hands

shaggydog365 · Apr 15, 2013

^^ Yes, I just had this happen. Moved some larger plants from a cfl veg setup to my 600HPS.. exact same thing happened. light/heat/ humidity. Next time I will put them in the high intensity light for a few hours a day before slamming them under there...or start higher with my lights. They are @ 20 inches above the canopy right now though.

Stay the course. leave the leaves alone, they will prob curl too in a few days. just pay attention to the new growth. Don't let those leaves freak you out.

Vincent VonBlown · Apr 15, 2013

Your fertalizer or PH is off one way or the other. It looks like a nute deficency to me though...

The comment about salt build up, could be right if your not draining out of the bottom enough when you water.

Yes,some of them start to curl. That mean my plant have heat stress isnt it?
