Yellowing leaves during flowering

[Guest]

listen to this man

no...knowing biobizz products, I'm sure your ph is not good because you give them the correct amount of food.lower the ph to 6, feed them normally.The same happened to me, I lowered the ph to 6, fed with 4ml grow, 4 ml bloom, though I was using great canna dirt.Well it worked.You can lower and cut the grow food later in flowering, not yet.
Algamic cntains micro nutrients and growth hormones; some say hormones delay flowering
still adding a little to every watering supplies the plant with all the micro nutes she needs.

So far, no need for it, just try my trick.damaged leaves wont recover

Is the plant turning like a neon green? If so you are feeding way to much nutes and water. basically drowning them, and killing them with nutes i would feed with nutes twice then next feeding with water only. Make sure that your soil is dry to at least 1-2 inches down or when the pots feel super light. then feed again. I made the same mistake thinking i have nutes ill just keep on feeding them and those nugsz will be huge. Well i was wrong i drowned and nute nurned many a plant.. Sucks so ease up on the feeding. And all will be good. Hope it helps some im not no guru just something i remember i went through. peace..

Did anyone ask about above ground environment...?

Thats could happen from low light and wind burns too.

I was at a grow seminar at the new Dampkring grow Shop recently - most others there seemed to be growing for coffee shops - so serious stuff

one thing that the speaker was adamant about was that you should always use nutes and growing medium from One company - doesn’t matter which - but different companies have different nute mixes which are designed to work together - thus Canna bloom and Bio Bizz Bloom will not contain the same balance of nutes - but use the same companies grow as well and you will get all the right nute mix in the Pot/tank - mix products from different companies and you will get problems - which you should be able to overcome if you are really good at plant nutrition - but for newbie’s (and because I have only been using specialist soil and nutes for less than a year I am a newbie in this case) the advice is STICK TO ONE COMPANY

So you are sying that if I am in the 3-3-1 period of the feeding schedule that I should be adding 3-3-1 to EACH watering? The guy at GHBB told me that was the amount needed 1/week. So if I watered 3 times in a week, I would need to add 1-1-1/3 for each watering.

Also I know I am not over watering,, I have been skirting with underwatering since she's been flowering. Right now, I am at a point where watering once per day is a little too much, but she starts to sag at the end of the 2nd day. So I have been watering every other day, and that seems fine.

Also, i am starting to get very confused about the whole PH thing. I thougt I had it down, but now I am not so sure.. The book I own (The grow bible by Greg Green) and another internet "how-to" both state that 6.7 is the best PH for nutrient uptake. I have also read other gardening guides that state 6.5-7 for most plants... Now someone on here posts a chart which shows 6.5, and then a poster that tells me it should be 6.0???

What gives?

If watereing every other day is needed, it sounds like maybe they are rootbound? or in a very hot/dry environment? I find my girls only need watering every 5th day. I try and let them dry out as much as possible than feed/water slow and deep.

She is in a 5 gallon pot with average humidity of about 60% and temperature that ranges from 80-85 degrees in the day and 70-75 at night. I water very slowly, adding bits at a time and letting it soak. It's possible the soil I am using has poor water retention properties. Before she started flowering i was going 2-3 days in between watering. I have detrmined watering amounts by very slowly adding water and letting sit until runoff.. Then backed it off until no runoff occured. I feel I am adequately soaking the soil.

Ok. You don't really want your ph higher than 6.5 even in soil.

Your unsure about how many ml to feed your plants. This thread has the nutrient levels for mj at different stages of growth. http://www.angelfire.com/cantina/fourtwenty/articles/profiles.htm Find veg, flower, seedling, etc..on the chart and it will give you rates to try for n,p,k,mg in parts per million. Go to the bottom of the page and enter your nutrient bottle net weight, total ml, ml used, and % elements like 5% calcium into the calculator. It will give you the ppm's your using. Compare to the stage of growth your in. Try to achieve a 4:2:1 ratio of potassium, calcium, magnesium. Now there is no guessing. If you get lucky you might can find the ppm's of each element already figured on the website, bottle, or in the instructions. To convert k2o to just k multiply by .83 and for p2o5 multiply by .43. The calculator makes this conversion. If the numbers you find somehow are in the oxygen form on the bottle in ppm's like 130 k20 when you use 5ml you can convert to just k 130 x .83= 108 ppm k. All the numbers recommended like a 100-100-200-60 ppm nitrogen phosphorus potassium magnesium in flower are in their pure form and not the oxygen form.

Does that help at all?

Thank you sproutco for the usefull resource. I have 1 question. Once I calculate the PPM levels of the nutes, how often do I need to feed the plant the required amount of nutes? Is this the level reccomended with every watering? Per week? ??

For example... In growth phase, the table lists N requiremens as 150-250 PPM. How often is this applied?

CLF = constant liquid feed. Do leach your media with straight water every blue moon.

CLF = constant liquid feed. Do leach your media with straight water every blue moon.

So just to be perfectly clear... I would feed these levels at every watering? And flush my soil every once in a blue moon?... Or by leach, do you mean just to water it with pure water?

 

[sproutco]

Feed with every watering. Try to get runoff from the drain holes. Maybe 20% of what you put on. Be sure to adjust ph after mixing fert water for best results. Switch to just plain water every once in a while. You don't have to heavily leach and pour alot of plain water on. Good advice?

Thanks sproutco, that is incredibly helpfull. Sorry to be a pain.. I am just trying to get a firm understanding of your advice. How often should I water with plain water, and for how long?

Thanks again for pointing me at that resource.. Awesome stuff!

 

[sproutco]

fert - fert - fert- fert - fert - plain water - repeat. Be sure to get runoff from the drain holes. If you have adequate runoff with the fert applications then you can get away with not having to apply plain water so much.

Thanks man! I am just a newb feeling pretty lost... This is incredibly helpful.. Now I won;t feel as though I am shooting in the dark and hoping it works out.

 

[sproutco]

If you look at all those ppm numbers, you might find your fert does not do what it should. You might have to add something to it. Or increase it or reduce it. Don't feel restricted by using store bought nutes that don't work out just right. Read my thread about making your own nutrient solution below in my signature. You can have your nutes anyway you want them and come out better with getting to target levels closer and saving money at the same time. Good luck!

su44us : listen to sproutco flowering plants need lots of nutrients, therefore feed them, and on sundays, let them rest plain ph corrected water,

I gave you a simple solution because you must get started with finding the good routine for your plants.Most times, when things go bad, watering once with plain water, letting dry, then watering with ferts fixes things.yo may consider using some additive, like alg-a-mic, that contains growth hormones and tons of micro nutrients.It kind of slightly prevents imbalance.

Growers have been using s.t.e.m. (soluble trace element mix) for over 45 years. You can use 1/8 to 1/4 teaspoon per gallon of water (3.8L) applied once when the plants begin good vegetative growth. You can repeat maybe once more 6-8 weeks later or as needed http://www.scottsprohort.com/_documents/tech_sheets/H4078STEM.pdf There are other companys that make similar trace element mixes like Masterblend.
