Leaf Diagnosis- Cant tell what it is

Is your soil coco based or peat based?

Also, what pH is your water?

To me, this looks like one of the many fuck ups I've had along the way: pH

I had an entire plant looking like this because I accidently doubled the amount of dolomite lime I added to my soil blend. Fought with it all the way till harvest. Your still in the early stages if it is pH, so I'd go ahead and buy a cheap soil pH kit from Lowes and see what its reading.

The cheap soil test kits aren't super accurate, but it will at least tell you if your soil is too much acid or base, and you can work from there. A good soil and water pH tester would be better, but if you don't already have one the cheap soil test kit will at least give you an idea.


Whatever you do, don't go adding nutrients just yet. I can all but garuntee its not a deficiency, or if it is, its likely related to pH or an imbalance of nutrient profile preventing proper uptake. Work on getting your pH in check FIRST before anything else

Will do, much appreciated
no info on nutes environment lighting watering practices.

Hit it with epsom salt ...mag add microbes to it.
research what microbes do, microbes regulate the ph at the root surface, the soil you buy or the cocco is ready to go if you had something that is of quality, soil or cocco companies are not going to sell stuff that is not able to be used they wont stay in business. Water in at 6.0-6.5 depends on what your using 6.5 for soil. Microbes take care of it after that.

And I have learned that autos are lite feeders what ppms are you feeding it at. other than the deficiencies it kind of looks stunted from a hot pot. To me maybe idk no info. or you just under feeding it and over watering it idk no info.
flush it really good vac off the crap in the tray renute at 1/2 strength add mag add back microbes. its about all you can do, reset the pot, leave it alone let it do its thing.

It is biobizz light mix, fed with terra aquatica (general hydro) organic bloom and grow. There are heat problems but this specific brown blotching is unique to this plant in the tent. We always ph our water to 6.4 and I doubt this is an excess nute situation because we had ph problems before getting the bluelab ph pen and we flushed the plants 20 days ago with 6.4 ph water and watered with that ph ever since. Ofc any of you could be right but so far among your suggestions the most likely to me are calmag deficiency or heat. I doubt I am overfeeding, since these arent salt chemicwl nutes and I always feed a little less than advised on the label.

The tent reaches 31 32 c sometimes, we have problem with ac and I know it stresses the plants but the other ones are casually stressed while only this one has brown black splotches on the leaves.

With this info, any new comments guys?
Thank you all for each of your advices.

Looks like multiple deficiencies. Could be locking out due to PH being off in ur medium.

Well we water every 3 days until runoff with 6.4 ph and the soil is an unamended light mix with no slow release nutes added. Is it being a ph issue a high probability still?

Nope... if its not pH I dont want to just start making guesses. But if it is a pH issue thats left unchecked, here's what you can look forward to:

Thats not a ph problem looks under fed, could of used more food in veg and flower , more mag from the looks of the stem, before you jump on me about this, when you water in what hits the roots is what counts, your doing hydro at that point, thats why you water in at 6.5, microbes regulate the ph for the plant at the root surface after that, microbes feed the plant the plant feeds the microbes.

granted this could be a purple kush or gdp and its supposed to look like that. and actually it looks like its done ready for chop, probably only lost a little weight, im ok with it, it self flushed itself. their kind of supposed to look like that when you chop.

dont care to argue with you just wanted to give my opinion because you didnt ask for it. ph is important in hydro microbes do all the work in soil.

Proper nutrients and water in at 6.5 with an active robust microbe population and you your golden in dirt. plus everything else of course but worrying about the ph of the soil isnt something you need to focus on.

Nutrient issues related to pH...

Like I said, doubled my dolomite lime. Soil itself had a pH of almost 9, and I SWORE it couldn't be pH until I used my buddies soil pen to check. Luckily, the EM1 I use has a pH of 3.5 so I was essentially just doubling that up, watering with water at a pH of about 5.0-5.5 and it helped keep her from completely frying.

And it was at harvest time, this was the "heres the final pic of this fuck up before I cut her". And to be honest, even though the harvest wasn't the best in terms of quantity... quality wise, she was probably the best White Widow plant I've ever had. Got a clone of her running right now (completely green this time tho :p)


Long story short, your not WRONG... it was nutrient deficient, but not from lack of nutrients lol

I went to GWE clicked on plant problems and saw your exact symptoms with the cure. Good luck.

I checked that website now, just to be sure, calcium deficiency seems the most similar but it feels like its something else combined. Do you reckon its cal?

Fed a good amount or cal mag, the color problem seems to have stopped expanding but now the edges are curling up. Raised the light a few centimeters just in case.

I have fed cal mag and the bronze patches disappeared. The leaves are still much smaller than all the other plants, glossy, dark green and burnt at the tips. The tips are curled upwards. The buds are much more foxtailish than others and this is the tallest plant. The dark green made me think of excess nitrogen and the burnt tips would support overfeeding. Did a smaal flush a few days ago, still waiting to see what will happen. Would appreciate if you could have another look at the current pictures and tell me if you can spot what the problems might be.

This is another plant. The grey/brown areas are crispy. The other plants never had grey/brown like this. What might it be?

Just because you pH your irrigation water to (whatever), doesn't necessarily mean you've effectively neutralized all of the alkalinity it carries.

I see, the amount of lime (bicarbonate and carbonate.) I will look into this but lets say that is causing the problem. The others 5 pots have no similar problems. But still, if this is the problem, how to fix it for now? I will look into it for the future.
