Leaf tips curling up and dying-pics

u are right, i dont think the humidity would cause the burn look u are getting, just the curling most likely at the RH u have.

i did notice the ridges in your leaves seemed a bit deep, which is usually caused by heat/humidity stress.

you most likely have a whole bunch of minor problems that are all combining forces...

dont do anything drastic, and be patient, it may take a week or even 2 to really bounce back completely... if it gets worse i may be tempted to try epson salt or something similar, but if thats not the problem than it could make everything worse.

I think I'm gonna boost the humidity. At least until flowering, which may be a while, at least until I get this sorted out.

yes, do that. the higher humidity (50-70) is better until mold is a concern...

if you are co2 enriched than i would recommend staying closer to 70% until week 3-4... then drop ur co2 ppm and RH quite a bit.

just hope you can solve the problem.

That's still what I think it is too. Perhaps I just need to give it a big dose of epsom salts. I only gave it 1/4 teaspoon per gallon but I've seen recommendations for up to 2 tablespoons per gallon. I just don't like the idea of giving it that much know what I mean?

Nah, I'm not saying that at all,I'm just saying what it looked like to me, because it's exactly what my plant was looking like.

I wanted to update the thread. Sorry I haven't been around for a while. My widows are now on week 4 of flowering and are doing great. I got the deficiency taken care of and they are all doing awesome. 5 more weeks to go. I can't wait!!!
