Can Anyone Maybe Diagnose these two please? Feeling low on hope 🙏

[WorriedPlantParent201]

Hope they’re saveable thanks in advance for any help. I’m providing a ton of info in my original post so please read it all, kinda need a solution asap time is getting short they’re gonna need either water or flush or a feeding and/or some calmag soon. Which would you try first?

I been told on other forum websites that it is calcium deficiency, nutrient burn, nitrogen toxicity, and after googling calcium deficiency I’m thinking myself it might actually be potassium toxicity blocking calcium. These people refused to elaborate after I said that, maybe it offended them lol but yea so I’m still kinda lost on what to do.

Yellowing discoloration maybe rusting on two of my biggest girls . The oldest one with the biggest new tops is in MG potting soil. Started feeding her at full strength 2 weeks dose of FF trio when I first noticed the bottom leaves tips yellowing and cytoclydons lost their colour. She was 18 days old

The younger one with the smaller new tops is kinda having similar symptons it looks like. I fed her with 2 weeks strength when she was 12 or 13 days old. Her discoloration started sooner. From the bottom as well. And she was started in miracle grow but has been transplanted into Promix HP. I didnt prune the roots though so theres still a little MG.

Side note this one has lots of roots coming through the drain hole right now, whereas the bigger and older one in only Miracle Gro soil I can’t see any roots under that one.

also have two more girls in same tent. Smaller. But prettier, leaves are green. They’ve both been fed too just once as well. Smaller one at quarter strength when her first leaves were yellowing. seems to have fixed her tho they might have even gained back some of their green. and the bigger one at full strength.

The light that is closer in the pics is cause its 600w, the one that’s further is 1000W.

Haven’t been PH ing just because the tapwater in my town has always worked ok before and so I don’t even have a ph meter or anything because I’ve never saw a need. Also I probably can’t get one right now cause im broke so I hope it isn’t ph issues lol. But if it was a ph problem wouldn’t all my plants be having it anyway and not just 2 out of the 4?

RH usually stays between 40 and 60 right now. I try to keep it between 50 and 60 though. kept it 65 to 70 when they were younger. it only goes down to 40 overnight sometimes when my hanging towels dry out. Also I sometimes let it go down just to help the frigging MG dry out.

And temps were 23 to 30 usually 28ish. Lately I brought it down I have a fan in there and Its usually 25 to 28ish. Celsius sorry idk Fahrenheit.

If there’s any little pests they’re very sneaky and still, because I been looking very closely

Also the plan was to feed then water then feed then water .

Thanks in advance for any help!

I’ll attach some pics. If I left anything out please ask

I’m a bit of a worried parent here today as I see the discoloration slowly spreading, and I haven’t really gotten the same answer from more than one grower yet haha.

Starting to lose hope of finding the help I need starting to feel like giving up and just winging whatever I think is the best plan.

attaching pics of them in their starter pots well my oldest was alrwady transplanted actually as youll see. shes also the only one left in straight MG. and current photos showing the deficiency or whatever it is.

Sorry if im long winded

Its starting at the edges of the bottom leaves and slowly moving in from the edges

Take some pics without the lights so we can see them in natural light.

[beachglass]

when are you transplanting ? What lights? Soil? nutes? What is temp and humidity.?

[danniep40]

MG is not a cannabis friendly soil and most don’t feed nutrients until your able enough to get runoff to check PPMs. What kind of water are you using and are you ph water

[randall67davis]

Looks like a PH issue causing other issues. I had that issue not to long ago. PH not right nothing else will be right. Check soil PH as well

Might sound crazy but I would flush with something like sledge hammer by fox farms then wait a couple days then light feeding half strength until they perk up and showing new

dannie40quote-when are you transplanting ? What lights? Soil? nutes? What is temp and humidity.?

[randall67davis]

half strength Alaska Fish 5-1-1 This shouldn’t burn your plants

[kdawg]

As for your lights look up the actual power draw at the wall. This will give you the true wattage output. MG as mentioned isnt good for these plants. Keep in mind the promix is basically inert. On plants that young id start with 1/4 dose of ff nutrients then work up to 1/2 dose and later on full dose. The better roots are due to the promix which has micro nutes that are beneficial to the root zone. Hope this helps.

[randall67davis]

Dont give up. post your growing set up, light schedule soil mix, lights, liquid PH, Soil PH, tent temp, humidity and all of the stats. People will be able to help figure out whats wrong and get you pointed direction.

Im guessing PH causing lock out and the plant is eating its self. Alaska fish emulsion 5-1-1 is easy on plants Correct pH and everything will fall in place. Flush then trans plant into bigger pot then in a couple 3 days try the fish. Fish emulsion also helps free up nutrients to your plants and feed.

here is a pic if 7 week old plants and all i have been feeding is 5-1-1 and micro nutrients, Ph for liquid has been 6.3 average and soil Ph is 6.8

[Aussie_autos]

Hi i would check ur ph of ur soil and of ur water there could be something a miss there . And to look at the leaves to me it looks like it could be one of two things magnesium def because you get that lighter green going from the edges inwards but the viens stray dark green and potassium def is very similar to the magnesium def and i do believe that zinc def is very similar aswell

[OGIncognito]

What medium are the others in? Better pics and over all plant pics in clear light would help. As mentioned the MG is not cannabis friendly… doable but often issues. Personally I wouldn’t think NPK would be needed with the slow release NPK in the MG and I would water only that plant with calcium and magnesium. It’s truly a guessing game with knowing your PH, macro and micro nutrients have a PH range that their absorbed in

[OGIncognito]

If checking PH is not an option? I would feed or water with distilled, it’s neutral and sold everywhere and cheap

[WorriedPlantParent201]

Damn do i need to write that all over again :(. getting used to this site. Im thinking now im not even gonna find any calmag either in this town ive called just about all stores. im probably screwed.

[danniep40]

They have calmag on Amazon along with ph meters

[danniep40]

@OGIncognito so when you use distilled water and you add nutrients to feed you don’t adjust ph ?

[WorriedPlantParent201]

Yea true, probably also would take time though, time that my girls may not have. When I order stuff its like a month usually

[danniep40]

@WorriedPlantParent201 if i was you i would catch rain water the best natural water to feed plants with and it’s free

[WorriedPlantParent201]

The reply i accidentally deleted lol

Wow thanks so much everybody im blown away. So helpful.

Based on everything you guys said, I think I will try a flush, then when theyre dry a transplant, im usuallt pretty good with a transplant, I think so anyway hah. Ill put the girl thats still in the MG into a huuge pot, into promix HP. The other ones ive already put into promix HP, at the last pot up.

And then after they recover maybe I try some calmag if i can find some in time, (starting to lose hope on finding it but yea im searching) on both of them. And then maybe reduce the FF dose im feeding, at least for the one still with MG but maybe for both idk, until they hopefully look right again and then maybe work back to normal dose FF? and Maybe a bit less still for the one with MG.

PH checking might be out of the question for now sadly , I think i have to pick between the calmag or PH ing. and im thinking calmag. Maybe get the one with iron in it too ? Or just General Hydroponics Calimagic or do you guys think itll matter much?

[WorriedPlantParent201]

Yay or nay? please???

[kellydans]

OK , I would purchase some organic cannabis friendly potting soil Happy frog , ocean forest or roots organic would all be a good choice. Gently do a transplant couple weeks you be fine ( Get out of the miracle grow soil ). The Cannabis friendly soil will carry your plants 4 or 5 weeks without feeding. @Oldguy May be able to help with availability of products. Just my thoughts good luck

[Oldguy]

@WorriedPlantParent201

into promix HP. The other ones ive already put into promix HP, at the last pot up.

That’s a good medium. Very friendly to use.
No nutes tho. They’ll only get what you give them. You’ll have to start feeding pretty much right away. Lightly.
Might have to water a bit more often with the HP ( soil less ) than you would with the others that @kellydans listed. All good soils too btw.
The Gen Hydro Calimagic will work fine if that’s what’s handy.
It’s what I use.
