Maybe Cal/mag issue?

[Sauce]

Strain:Mango Auto
PotSize: 2gallon
Nutes: Tri , about 15 mil big bloom, and 5ml grow big
Soil: OF and perlite
Lights. Mix- Sunlight and T5 8 bulbs
PH:6.3
Age 27 days

So this issue had started and I gave it cal/mag/iron in it's last 2 feedings. I don't think it's helping at this time, I think it might still be getting worse. It did just get it's second feeding yesterday of the nutes and the cal/mag/iron.

I think it's a cal/mag but I am not 100% sure. Out of my other 6 plants, this is the only one showing this issue.

ur soil ph needs to b about 6.6 for calcium and mag to be absorbed proper.and im no expert but I bet ur humidity is low and that could cause patchs like that.when your leaf edges curl up like that means its to dry get it to at least 50% and she will be much happier.im sure someone will know exactly what to do,peace

Heat and dry environment, light burn, light too close, not enough air circulation (when dry and hot, strong air circling seems to make things even worse sometimes). These might be reasons for your troubles.

Or ph ?

Or everything together?

It takes a week sometimes for plants to react to nute changes.It could be low humidity like faded said seeing the curled up edges on those leaves.It's to early for bloom nutes. Just feed veg nutes for now.

Hi Sauce- ...you say these symptoms started after you gave her Ca-Mg and Fe? And the pH you gave, is that soil pH, or...? Good pics of the trouble spots,... can you get a whole plant pic, or tell us if others leaves are affected, and where on the plant it is,... I see some edge curling, which is usually a sign of heat/water stress on the leaves,.... how close are the lights? ....the yellowing and lighter tan necrotic spots look like Ca defc.; when you treated her, did some of the nutrient solution get splashed on the leaves while in the sun? Some of the other damage kinda looks like light burning you get from lensing effect from droplets.... once I foliar sprayed my plants outside on a foggy day, and not long after while I was away, the sun came out before it dried, and I got some similar damage like I see in pic #4... not the light tan, but the dull brown around it,... just a additional possibility... I gather, this is a combo product you treated with? I takes a couple-few days to get in there, and some progression of symptoms meantime is typical; Fe is not involved, even if your soil pH is low (more available in those conditions), but Ca and Mg loose relative availability as pH drops below around 6.0,.... So, give it some time to get absorbed and working,... the leaf damage won't reverse/repair, but progression should halt soon, granted the soil pH isn't too low, making what you gave her unavailable,.... get us those details, mate-- thanks!

Hey guys thanks for the answers I will give some more information.

Lights are about 3-4 inches away. This started as one brown spot a bit ago, but has gotten worse. Only in the past 7 days did I start giving it cal/mag/iron. During the day they been out side. When the sun goes down, I put them in their tent. Tent is around 75-81F. RH is around 40-60% depending on if it has rains.

The issue with the cupping, that I found out was due to it being out and having too powerful of a fan thats an older issue.

As for using bloom nutes, I have been trying to read alot about the Tri. And seen people using them as well. Some don't consider the Big Bloom to be bloom nutes. I have not given any tiger bloom at this point and will not till it starts to flower. Nutes been 1/4 to 1/2 per gallon. I mix about 2-3 gallons at a time, stir it up check the ph of the water.
That ph I gave was from run off and the control wizard soil meter I have.


Any time that I do feed, I always wipe the leaves off before the feeding is done. And normally pretty careful about pouring it in.

This is the one I used. http://www.plantlightinghydroponics...um-and-calcium-supplement-1-liter-p-2916.html

I will take some more pics in a bit and post them. Thanks for the information so far.

PH was dropping about a week ago, i added an ounce of lime to it as well. But no, this has started a while ago. I just got the cal/mag ect and was able to give it two feedings of it so far. I didn't know if it would reverse it or not. But I will keep it eye on it. Just wanted to see thats what you all felt it was as well. Just thought it was odd that out of 6 of them, only one getting this issue is her.

Also those holes they are not from bugs. I check my plants over once a week pretty well. Those used to be rust spots, and some parts where I smashed two plants pots together and the leaves got cought ect. My mistake on that, but since it was weak didnt like it at all.

I didn't get to test my run off last night couldnt find my ph tester pen -.- But that soil reader is good, muddy recommended it to me. My last test showed the soil was around 6.2-6.3

yeah I would try an get it up a little more 6.5 would b great.and yeah big bloom is not just for flowering,people get it confused cause its got the word bloom in it.i used to use it starting week 2 in small amounts its organic but can still burn.

Yeah I think so. I thought the same thing as well till I started reading a lot of grow logs and found people who use it Right now, there is lime in the soil, so it's slowly raising the ph back up. And I started with the grow big first I don't htink that was the right thing to do. So on my new ones thats whta I will be doing. Starting with the Big Bloom, then adding the grow big about a week later into the mix.

Just use Big Bloom as base "maintenance" feed and either Grow Big or Tiger Bloom as the "stage specific" feed. Mix em together....just fed one of my plants BB, GB and Cal/Mag...one shot.
