burning/droopy leaves, how to fix?

I have been growing an autoflowering strain on my windowsill, moving it around the house and leaving it outside on some nights. It is about 5 weeks old and has been flowering for about a week or so.

a couple days ago it survided its first real storm, some short lived heavy rains and long night of powerul winds. It has recovered mostly and is standing up straight again but I have noticed on the tips and the middle of some of the larger fan leaves are brown dead spots. The four large fan leaves on the bottom half of the plant are significantly droopier as well.

I should also mention that some of the white hairs have turned brown even though theflowers are young,

Is this just the effects of some harsh weather? or could their be a larger problem?

I am using a pretty stabdard soil mixture made mostly of peat moss worm castings perlite/vermicuite.

I will try an dget some photos up soon, been having trouble finding a simple photo resizer.

thanks for your help and suggestions.

Hmm could be magnesium deficiency (brown spots and tips on leaves).

Or could be pH issues or over or underwatering perhaps.

What water are you using and what's your watering schedule? Are you feeding them?

Pics would help, have you tried irfanview for resizing? It's free and it works.

You don't think the symptoms are just from being knocked around by the storm?

If you're gonna leave it outside best leave it out every night- otherwise when you do it might be a shock to it's system.

From these pics you can see what I am talking about.
The leaves really close to the budsites are in pretty good health its just the larger leaves that are the problem.

I am aware that in flowering fan leaves tend to yellow out a bit but this looks a little more drastic.

in Past grows I have gotten to this stage and then never really had the buds fully fill out. I would to do everything i can to get this plant yeilding nicely. so all the tips you can share with me will be appreciated.

one little problem that I have though is that I won't be able to buy any fertilizers for almost two weeks. The only cannabis related gardening stores are in amsterdam and withmy work i won't havetime to get over thereuntil later. so maybe homemade remedies will bethe best for me for the next shore while haha

Mostly storm damage I think- at least the major damage at the end of the bottom leaves.

There is a bit of brown/yellow spotting which would probably indicate magnesium and/or calcium deficiency.
There are a few things you can do to help- if you are using tapwater are you letting it stand for 24 hrs or so to let the chlorine evaporate?
Be careful not to over or under water.
They might benefit from some epsom salts (source of magnesium), say 1 or 1/2 a teaspoon per gallon of water.

Too alkaline or too acid water could cause the spotting.

Have a good look under the leaves to make sure there are no critters causing the spotting. I don't think so though.

They don't look too bad at all, I think most of the damage is from the storm.

This strain looks like it's "Afghan Kush Ryder". ??? 100% Afghanistan landrace back crossed with Ruderalis.

If so, The pistils will go 'reddish' at thier tips giving the appearance of dying or just something is wrong. This is normal.

Other than the weather beaten look, I see what appears to be Calcium(CA) problems & not real bad. Do check for pests on the top & bottoms of the leaves & at branches. Paying closer attention to the areas with the 'spots'.
