Get Help for Cannabis Plants Problems as Quickly as Possible!

American Pie Auto 2 weeks into flower exhibited this spotting last night when I went to water. Originally thought it was septoria, still may be, but looking at another leaf this morning started to think it may be something else. I have 4 plants in a 2x4 tent under 300w lamp, 50-55% RH and temp around 78. I removed the affected leaves thinking it was septoria, but figured I’d ask here as I haven’t come to a conclusive answer as to what is going on. THANKS!

The plants in my flower tent are showing symptoms and I don't know what it is... At first I thought it was nutrient burn but is weird because I've been giving 1/3 of the nutes.. can someone help me identify what Is wrong?

Details:
Light Cycle : 12/12
600 watt HPS
Organic grow using biobizz Nutrients and compost teas

I have looked at the infographic but by the time I had reliable service to compare, my plant looked to be a bit too far gone to identify with surety.

Im using 2 300w led and 2 200 w led to supplement, 5 gallon pots, fox farm happy frog soil. All of that was keeping the plants looking great. The rain, humidity, or change in lighting source caused the issue, I'm just not sure what the issue was to try and fix it. I'm pretty sure one plant is donezo, one is struggling, and one is still thriving like nothing ever happened. Assuming the one that's thriving is just a resilient strain or that since it was less leafy, the moisture didn't attack it the same.

Did you look on the main GWE site at the leaf problem identifier? What soil, size pots and light watts are you using? The rain might have flushed out nutes.

I started my grow a couple months ago and everything was going well enough. I have a 4x4x3 grow tent. I live in an area affected by the recent hurricane and lost power for 10 days. In order to make due (with light cycles) I had to put my plants outside during the day.

ONe day, while at work, it rained a crazy amount while the plants were outside. After that I noticed one plant starting to look unhealthy and presumed that it may be a case of over watering, in which I tried to wait on watering to see how it fared.

With no change, I've since watered it once. I wanna know if I could rehab this plant or not and what the issue may be if not. I have 3 plants, total, one is still thriving; this one pictured is struggling, and another seems to be getting sick (the same way the other did.). I have power, now, and have returned them to the tent but I'm worried I made it to the flowering stage and may have lost 2 of my babies. I used seeds that I've collected, so I couldn't even try to give a strain. I'm open to all help. Thanks.

Excellent chart

I think what you have is a magnesium deficiency. Please look here -> How to fix Cannabis Magnesium Deficiency (Mg) Pics & Symptoms (growweedeasy.com) or here -> How to fix Cannabis Manganese Deficiency (Mn) Pics & Symptoms (growweedeasy.com). Overall your girls don't look bad, but I would do a bit of reading and comparing before you settle on a course of action. Happy Pharming and keep us posted on your progress. Just a side note - If you plan to continue with your indoor grows it might be a good idea to invest in some cloth/burlap growing bags that will allow better root respiration.

I am beginning to struggle with my first grow. So far it has done well but it is now starting to lack things that I dont have a well enough knowledge of. Any help is advised. I'm using a marshydro ts600 led light. Using general hydroponics three step nutes. And watering only when I think they need watered. So i could be underwatering. Idk lol

[Askdog]

Oh oh oh, right that makes so much sense to me now as I just realize at the flowering stage they need more Magnesium & sulfur, I just spotted that my wedding cake and the breeder's gift is also having slightly yellow dot in the immobile leaf, I got it, Epsom salt is arriving tomorrow and let's see how this goes, will update in a week to let you know the status, thanks Man!

[Askdog]

Thanks for your reply, so meaning that I mix Epsome salts with a few gallons of water to rinse it off all the nutes, leave them to dry with no nutes at all for a few days and see how they react? If the burnt mark not increasing I would add back little N but more P & K for it, right? Do I need to dose them with the Ca.Mg.Fe.S.Cu.Zn.Mo.Mn bottle so they have all the micronutirents? Thank you. I assuming the Epsome salts is with magnesium & sulfate help the immobile upper leaf?

[SoOrbudgal]

Answered your own question. You need alittle dose of N whislt in flower but PK is the minerals they need more during bloom. If you already just watered ( no nutes just water ) i'd let it dry then use Epsome salts i use 1 tbls per gallon of water. Rinse the roots with that, allow to dry and see if within a few days if that does not stop the issue.

**Upper leaf near bud showing rusty dot

Hi there,

Newbie first grows, as usual, experienced nut burn, been flushing adjusting PPM around 1,000-1,300.
Don't mind the burnt edge that's caused by nut burn, but not sure why after flushing the leaf tip still bends down.
Also, the leaf tends to get pale green not sure what is missing.


I am in a place where I have limited access to the individual types of nutrients.
I can only purchase a premix nutrients bottle.
I have one with N, P, K
Another one with NPK 15-15-15=45%, Ca.Mg.Fe.S.Cu.Zn.Mo.Mn around 8%.

I'm growing with organic soil so I think the micronutrients are covered.
Not sure still showing the rusty dot in the flowering stage.

My guess could be some of the micronutrients lockouts.
Not sure what caused it.

My setup is below.
1.5 x 1.5 x 2m tent.
Lighting with 400W LED lighting for each cannabis plant.
The LED light is close to the plant, I have an iPhone app with Diffuser covered, showing 900 PPFD on my cannabis, I think it's not a heat burn.
My room is always on A/C at around 25 degrees C.
I am planting 3 different strains, one is wedding cake, one is the breeder's gift not sure what it is, the last one this one showing here on the picture I believe it's OG Kush.
I've made such silly mistakes having them experiencing nut burnt for all of them, however, the wedding cake and the breeder's gift were recovering nicely after flushing.

Only this OG Kush is having too strong nutrients even at Veg stage they were showing pistil, even worse after flipping the switch, at flowering week 1 for this OG kush is already full of pistils.

I suspect that the nutrient is still burning the plant, or the burning is causing the micronutrient lockouts.
Should I flush them again and add just P to my cannabis for flowering bud purposes?

Or if anyone can help to identify the problem, I much appreciate your help.

Thank you thank you.
