Yellowing, Droopy, dead looking plants. PLEASE HELP.

about just over a week now i gave the girls the normal watering they usually get every 2-3 days (when the soil feels dry) and the morning after i woke up and they were all drooping and i started noticing discolouring, now theyre like this.

Setup: 1 125w CFL Light, 1 150W CFL Light, 3x3 reflective grow tent, normal fan. plain potting soil.

The temp in there is usually between 75 and 80F and the humidity around 35-40 when lights on, of course the night time it drops. Can ANYONE tell me what im doing wrong and what looks to be the problem with these. As i said, they were beautiful then after a watering, i woke up to this and it just wont get better. They also have been stunt in growth the last little while as well i believe. Little to no new growth. PLEASE HELP ASAP.

I just want my happy beautiful girls back

buuuuump

What have you been watering them with? What PH? coz that is most likely your problem.

fernbrook spring bottled water

are you adjusting the PH of the water. bottled water tends to be pretty hard, you are better off buying distilled water if you wanna buy bottled stuff, or RO water from an aquarium shop.

Buy ph up and down, use a 10 dollar Chinese piece of shit PH meter (from ebay) use tap water and soil that feeds 3-6 months. Then all u gotta do is ph your shit to 6.5 and water, and wait. EASIEST SHIT EVER. It's not rocket science amigo, you'll be ok.

Seriously....PH?

I get so tired of people posting about having the correct PH as a fix to a plant's problems.

First....it looks like he's growing in soil. Soil buffers PH issues. I water straight from the tap with a PH of 8.1 and have zero problems. Chasing the perfect PH to correct a nutrient problem is like painting a car that has an engine problem.

The OP didn't give us a clue of what he's doing with his nutrients. If those plants were mine, I'd up-can them to 5 gal pots that have good soil (I like happy frog) as I suspect that they have become root-bound in the containers they're in now and are missing out on needed nutrients.

If any of you are growing in soil.....toss out your PH meter unless you're using well water that's very hard.

Lol, really? I've found that most issues start and finish with PH. And this guy is watering with bottled spring water which is probably pretty hard anyway.

8.1 is very high for MJ which prefers a more acidic root zone, don't you get micro nutrient lockout problems? I grow in coco now after switching from hydro, so I've never used soil, but I didn't think that it could buffer that much of a gap.

Not checking PH as the first step of troubleshooting is counter to everything I have ever read, heard, seen and do when problems come up.

Yeah i think lilroach has over simplified the process a bit, but i get his point. Good soil = easy sailing.

However i think you're both off! Classic overwatering for starters, 2-3 days or "when it feels dry"? Nah you gotta pick it up and make sure there's no water in there man. Under a couple cfls that probably takes more like 4 days. Roots are probably rotten, not taking up enough nutes anymore.

Let's put it this way. Have you checked your ph? Because that is the first thing I would check. If your ph is good, then move on. It looks like a ph issue to me. The ph of your water might not matter, something in the soil might be off. There are multiple things that can cause the ph in the root zone to go wild.

I can bet it's a ph issue. If it's not then it needs food. It either can't take up nutrients, or it needs more.

I would check the pH of the water first. Then I'd flip one of those boogers upside down and pop the pot off and take a look at the roots. It may be just as simple as it needs feeding.

Right forget the ph up and down your growing in soil ph isn't an issue Fact
the microbes in the soil produce there own cations and anions to level out ph using ph up and down will do more harm then good are you using nutrients if not then simply water isn't enough it looks like you have really hot soil those leaves are dark green indicating to much nitrogen which in turn locks out potassium and other micro and macro elements do not water to much let the plants grow out of it before feeding again do not flush more water means more absorbtion and uptake of nitrogen ive studied your pictures and i can definetly say to much nitrogen other wise its magnesium def which i doubt as at that stage of the plants life it doesn't demand much

advising people to buy cheap equipment you obviously dont give a shit those cheap meters give off the wrong readings the range of which it could be out is to high plus its soil you would be wasting 10 dollars on something you dont need never advise people to buy crap and soil that has 3 months worth of feed you mad you will never achieve perfection that way its just plain lazy ye its not rocket science but i think you need some science lessons my friend

Wrong

Listen......Do farmers adjust the PH of their soil? No. Do outdoor pot growers adjust PH of their soil? No. So why is growing indoors any different?

I understand that PH is important to hydro....but it's almost always meaningless when a plant has nutrient issues with soil grows.

I don't let my tap water sit. I don't adjust for PH, and my plants are green from beginning to end. I average 5 ounces per plant (not record breaking, but certainly not a sign of plants not getting what they want). I water/feed EVERY DAY.

You people can do what you want. I gave my 2 cents and I'm a guy that has no nutrient or plant problems at all. It's sad that a new grower will take the advice and chase the perfect PH while his plant suffers in the mean time....but I guess we all have to learn sooner or later.

A Fucking men someone who talks sense

leave them girls to grow out a bit DO NOT FEED DO NOT ADJUST PH DO NOT FLUSH
FEED only WATER UNTILL LEAVES GO A LIGHTER GREEN THEN ADD A HALF DOSE OF NUTES AND WORK YOUR WAY UP PLEASE PLEASE PLEASE dont listen to people telling you about ph adjustment and feeding more nutes i guarantee if you follow my advice they will recover Good luck
