Droopy leaves in flower, yellow/rust spotting. Help please!

[seaside blues]

Hey guys, working on my first grow and this lil lady is having some problems I think. I've been thinking a mag or cal deficiency, but I'm not sure.
I'm new to this.. but I've read through the guide to sick plants and tried finding stuff, but it just kinda confuses me even more. I'm leaving tomorrow for 3-4 days, so I hope to find out what this it before I leave!! Anyways. Here you go, please help!

Today her lower fan leaves are very droopy.. wasn't like that last night. She's been yellowing on those lower leaves for the past couple days. I know plants start to yellow late in flower, but she still has 4 weeks left or so.. is this normal?? I gave her a good flush 2-3 weeks ago and watered with some bloom nutes at (10-15-10) and molasses afterwards.

Also, I noticed a couple rusty colored spots on her leaves that weren't there yesterday. There are pics of everything below.

Yes, she needs some magnesium and some minor potassium. How often are you feeding your plants? Molasses is not going to be enough to feed your plant.

Why are you not using your other kind? You can use Epsom salts with your watering; and for god sake please water that poor baby; either you are not watering enough when you water or you are going to far between waterings.

You should be feeding every 7 days; you can use molasses in your feedings if you want too; Schultz food does not have magnesium get some Epsom salts and feed 1 tsp per gallon of water or for just this feeding 1 1/2 teaspoon since they are deficient........ then from then on use 1 teaspoon per gallon of water.

You just are not feeding proper food enough; stop using molasses every water too. Use it once a week with your schultz, but make sure you do not listen to the directions on the back of the box;

Are you using the liquid plant food?

Thanks for the reply, Stitch. I really appreciate it!

I have Epsom salts and I will use the Shultz food when I water. And yes, it is Shultz Liquid Plant Food, w/ micronutrients.

Feeding hasn't been every 7 days, more like every 14 or so. Which I'm sure isn't enough for a flowering plant. I guess I was concerned about burning her or overfeeding.

On the Shultz food for indoor plants, it's 7 drops per quart of water, so 28 drops a gallon. Should I use half that, 3/4?

I'll take your advice and get this lil lady looking good again. I think I really need to start keeping a written tab on the watering and feeding schedule...

Thanks again!!

 

[MynameStitch]

The micronutrients in that food is stuff cannabis does not use a whole lot of like iron and manganese.


THey use calcium, magneisum and sulphur more than iron and manganese.

Well consdiering your using liquid I am not sure, because I never used liquid stuff before..... most of the time there directions are wacked out and way to strong so I would use HALF of what they always give you...... try 1/2 tsp per gallon.

if they require 28 drops that is around a little over a tsp if they used a standard dropper; of if you want take the dropper and use 28 drops in a tsp and see how much you get before using it so that way you know how much is half; but do NOT use no 28 drops per gallon; you want to be safer than sorry.

Ok, cool... Thanks Stitch! My next grow I'm going to buy some better nutes.. I know the plants would probably like it better than what I have!

I used half of what the directions stated and the yellowing/rust has stopped. Next time I feed, I'll put the drops in a measuring thing to see how much 28 drops really is. But now I definitely know the signs of under watering.. not even an hour after I watered, she perked right up. :-D

Just one last question if you (or anyone else) come across this again.. leaves that have been damaged don't recover, right?

 

[romdog11]

you totally need to keep a schedule written down. i didnt do that for the longest time and i was starving them then stuffing them and burning them to compensate it wasnt pretty. a schedule really helps.

 

[MynameStitch]

Correct! Leaves that have been damaged will not recover, but will turn necrotic slowly.
