HELP - Red lines on stems, pistils turning brown?? confused... (High-res Pics!)

Hey I have noticed these strange red lines running up the main stem and off some branches, and it seems the branches that are red, the leaves connected are getting red spots on all over them as well. Some are spotted red spots on the stems but it just doesn't look too healthy. Many of the branches are perfectly green and healthy, what is this red all about? Are there any deficiencies that would show as red spots/lines on the stems? Could it be a fungus of some sort?

Also, some of the pistils on my flower sites are turning brown... could it be heat stress or a more serious problem? Will they recover if I raise the lights up?

Overall, they actually aren't too bad maybe I just need more bloom nutes.

(Click and click again for high-res) (The first and last pic here may be the leftovers of an overnute regime a few weeks ago, look below for more recent)


More recent leaf issues, some leaves show as more red w/o the necrotic spots, looks like a rusty kind of red.


Close up of the red spots on the stem.


Not sure how well these came out, but I tried to get a pic in of the browning, I think there is some slight heat stress as the edges are curling up on the leaves around it.


Thanks in advance for the help, I don't mind handing out rep either! :peace:

That looks more like a Ca or Mg problem.

I've always had that idea, that they could be low on cal and mag because I use distilled. I have cal-mag on the way so hopefully that will fix it right up... figured the flora nutes had enough cal/mag.

Only reason I doubted it was a cal-mag def. is that it didn't fit exactly right with the typical look for them based on the pictures and info i've read about cal-mag deficiencies, because some of the spots and damaged leaves don't look like cal-mag def's but that is a good start at least, thanks for the response Boneman.

Browning pistils? Could that just be heat related... and did it cause any permanent damage that can't be fixed by just raising the lights (gonna be a big project as my box's height is at it's limit can't raise the lights anymore)

Some strains just look that way.

A little cal-mag wouldn't hurt anything either.

Solution to fixing a Calcium deficiency
To fix a calcium deficiency you can treat by foliar feeding with one teaspoon of dolomite lime or Garden lime per quart of water, Or Any Chemical/Organic nutrients that have Calcium in them will fix a Calcium deficiency. (Only mixing at ½ strength when using chemical nutrients or it will cause nutrient burn!)
Or you can take crushed up dolomite lime or garden lime in a gallon of water and water it in the soil. 1 to 2 teaspoons per gallon of water, which will be slow acting. Garden Gypsum, which is medium absorption. Limestone, which is medium absorption, Rock Phosphate and Animal wastes which are both medium/slow absorption. Note: Caution when using gypsum to an already acid soil (pH that is less than 5.5) can have a very bad effect on different types of plants by effecting the absorption of soil aluminum, which is poison to plant roots.


Now if you added to much chemical nutrients and or organics, (which is hard to burn your plants when using organics) you need to flush the soil with plain water. You need to use 2 times as much water as the size of the pot, for example: If you have a 5 gallon pot and need to flush it, you need to use 10 gallons of water to rinse out the soil good enough to get rid of excessive nutrients.




Pictures 1-2 shows calcium deficiencies. First one shows late, 2nd one shows early development.

Start with about 50% - 60% of the recommended dosage with your cal-mag. I mixed 3ml per gal of water and that normally did the trick...mix it up good and check your PH to make sure its at the proper level before watering.

Will do and will report back when it comes, probably going to be next teus or wed when it arrives. I'm using a hydro setup, bubbleponics, but I will start with 50% dosage and see how they react.

So the browning of the pistils is not something to worry about? I read it could be due to pollination but I am 99% sure I have no males at this point, i'll take another good look at them on sat. when I change out the res.

Ok, I got my cal-mag yesterday and added it for 6 gal at 1/2 strength... added 28ml all together for 6 gal about 5ml/gal... some of the leaves are starting to droop and look worse... the red spotted stems are back and tbh it looks worse since i've added the cal-mag. What's going on? I saw a gnat, I think, small black bug flying around in there... I had a small fungus gnat problem in the beginning of the grow 5 weeks back.. but they have been gone since then.. I don't know what is going on with them... the red spots are still spreading upwards on the plant.. Please help!!

It was cal-mag plus... and I was looking on the back and it had a fair amount of nitrogen in it? What's up w/ that... my plants are going into flowering now and I don't want that nitrogen... maybe that's what caused my plants leaves to droop?

Here are some more pics, 1 day after adding cal-mag plus... I also took all my three overhead lights and arranged then on the sides cause my largest was growing into the lights and they had more room... surely the drooping wouldn't be from that? That's the only other thing that changed... Here they are. Thanks in advance.



Notice the red stem, too... I thought that had gone away for the most part for a few days, now it's back -

one of mine had the red streakys on the stem but none on the leaves were effected.. My ph was off and once i corrected it the streaks went away.BTW nobody answers any of my quesions in my grow diary--what the hell...

Also, what kind of soil is being used?

The little bit of nitrogen that is in cal-mag shouldn't affect flowering. I wouldn't think that cal-mag at half strength would cause stress. It usually takes about a week to see improvement and I've usually had to give 2 or 3 1/2 strength doses to get it corrected. If you don't want the nitrogen there is some stuff called Earth Juice microblast. It's got a bunch of micronutrients in it including magnesium and it doesn't have nitrogen.
