It sounds like you are more interested in the hydroponics forum. This isn't the right thread for those type of questions.

i thought this was about nute stuff, not just soil. alright

Its about quite a few things at this point. I thought you were asking about hydroponic setups, which UB couldn't help you there. He likes getting his hands dirty ya know. If you got a question about nutrient deficiencies, or nute burn symptoms, etc go for it.

Serious seeds "Chronic" feminized. 1 month into flower. foxfarm nutes and soil by the book. temps at 74 degrees. watering about every 3 days. T5 flouros on top and sides. leaves on the bottom, middle, and top of plant are looking like this and eventually dying. plant looks great otherwise. yellowing, curling, brown spots, then eventually falling off. started happening about 2 weeks into flower and has continued since. 10-20% of leaves on plant look this way. any help? thanks

If it started happening about 2 weeks into flowering, its probably an N deficiency. Are you using Tiger Bloom, and did you switch to that immediately upon entering flowering?

N deficiency for sure, commit this to memory

extremely helpful. thank you uncle ben.

These girls (my first) are outdoor soil about 5 weeks veg.

We are using foxfarm grow big, and I *think* what I am looking at here is over fert or over watering or both. Every third day. This pic pretty much sums up the rusty curled tips descrip I have seen around, but I haven't been able to find another pic on the forum quite like this.

Note: I have been kind of being edgy with the water quality last four waterings. I was using RO from my kitchen water filter, but it was getting to be a pain to haul that much water out back so I started using an aerated barrel of tap water which I have been unable to pH test (tester on the way). I know the RO water is spot on so I am switching back to it immediately. New pH tester on the way.

Many thanks in advance.

Looks like some overferting to me. I wouldn't worry so much about the water. I fill up a 55 gallon drum and just scoop out water form it when I need it, and its tap water. My plants look great. I think alot of us will have water thats just fine for growing plants.

hi Uncle Ben,
can you please diagnose what is wrong with my plants. my pics are here:

Any advice is truly appreciated

dave + doberman... yes, i'm using tiger bloom. however, i did not start plant directly on it. i finished veg, water 1 time with only water, then started on 1/4 strength tiger bloom and gradually increased it. i did a bit of research on N deficient plants but found no info on what to do stop it. i'm a month into flower, and the research says not to add N during flower, but that the plant will not yield as much and it will continue to get worse without sufficient N. any suggestions on where to go from here? thanks.

Sorry, but no I can't. Your photo color renditons are not true, you haven't disclosed everything about your garden, plus I can not open up an image any more in this sorry excuse for a forum.

Recommend you get a book on general plant culture and learn what makes a plant tick. Fuck "the research".

What you have read is complete and utter bullshit. Just another myth perpetuated by ignorant people on MJ forums who know nothing about growing healthy plants.

To fix your problem, you just give it more N. It wont fix the affected leaves, but the unaffected foliage will remain lush and green.

The reason you experienced N deficiency is because Tiger Bloom doesn't have enough N in it to maintain healthy foliage.

If your leaves yellow, fall off, and die, then your plants ability to photosynthesize is reduced. When it is reduced, your yield then goes down.

If you can maintain healthy foliage until harvest, you will have a chance at the largest yield possible. I say chance because there are many variables that affect yield, but healthy foliage is the most important one.

Give them some Grow Big or any other fertilizer with sufficient N, and you will be on the right track.

Thank you UB and Dave....i will go ahead of give her a dose of grow big and hope that that puts here back on course. i appreaciate the timely, knowledgeable response. Thank you

Thanks for saying what I've been saying for years. Guess this ol pHart is just running out of patience after writing long posts on the issue. It's a sad day, but very typical, that the forum masses care more about product hype than the process of photosynthesis.

You are the voice of reason. I never got why people let their leaves yellow so much. "yea, but UB. AN's XXXX is great but my leaves are yellowing. Why?" Probably shouldn't have spent $100 on it since the High Times ad was "cool". Sorry, just my pre-bowl rant in the morning.

don't ask questions.
just read ub's threads and do what it says. the experience of having a nice garden will be the best research that you could do!
you WILL learn the plants after awhile, and even though failing is learning, you won't get far by having a garden that dies a month into bloom every time.

Someone else has to take up the torch too . If more people learn the truth and facts, and start educating newbies, then one day the newbies will stop passing on false information. Maybe one day all of us will be free of these dreaded myths and this perpetual cycle, and we'll all be better off.

Oh believe me, I run out of patience too. The mood I am in will dictate what type of response someone gets I should probably cut and paste responses for certain types of questions instead of typing them out

What I hate is what I perceive to be an extension of the entitlement mindset that is so prevalent in the world. We don't owe anyone anything, they need to take complete responsibility for allowing themselves to be manipulated by vendors and forum parrots who don't know shit from Shinola.

A newbie needs to do their homework. Sure we're here to help but when it comes down to the nut cutting, it's up to them, it's their garden. Not mine, not yours, their UNIQUE garden. To make it plain and simple, when growing this weed, make sure The Balance (of all cultural factors) is in place, don't force your plants, and just grow 'em like you would a tomato plant.

Having said that, I did a cursory glance at my outdoor "experimental" plants this morning (4 colas with the 2 lower ones very sub-dominant) and am already getting female preflowers on one. These plants literally came back from the dead after being totally fallen over due to a lack of water for a couple of days while I was on vacation.

nice to see you growing once again, looking forward to the results
