Yellowish Leaves

[dude0]

Hi, 2 of my plants have yellowish leaves, not all the leaf is covered, about half is. See pic below... what do you think is wrong? or are they meant to be green?
Also how much should I be watering?
All help appreciated

[dude0]

Please help! im worried on what to do !
:)

ps: the bit where i said "or are they meant to be green?" i meant yellow.

Hello. From what you are describing, it looks a magnesium deficiency. A little epsom salt will fix her up. Dont over do it tho. Add about a half a tea-spoon to a gallon of water. Watering, Poke your finger about 3 inches in the dirt, if it's dry, water it. If its moist. let it be. You can use the "lift the pot" method to check your plants. A light pot means you need water. Heavy pot means it's cool. hope this helped, peace.

[dude0]

Thanks for replying :) .... epsom salt?... is that just normal household salt?

it's not magnesium deficiency, you only get magnesium deficiency when the plant has lived an extended life, usually you'll get it if you double or triple harvest.

How old is the plant? it looks to me you're worried about the first leaves yellowing. this is normal, over the course of it's life your plant will lose a majority of it's lower leaves.. there's nothing you can or should do about it. It's pretty normal.

You need to distinguish what are.. and are not actual plant problems.

To see pictures of magnesium deficiency in a sugarbeet plant

[dude0]

Ok cool, thanks, il sleep better tonight :)

Thanks for replying !

You will never have a magnesium deficiency with a 2 week old plant.

The plants are experiencing a nitrogen deficiency. Have you started to fertilize them yet?

Hi, no i have no fertilizer, should I be using this? ... i am a 1st time grower, what do you recommend i do?... im in uk.

[Sensi Super Skunk]

You could use Peter's 20-20-20, but like most fertilizers, you would have to start by using 1/4th strength of the recommended water to fertilizer ratio, because fertilizers like this easily cause fertilizer burn. But organic fertilizers in my opinion are the best, because they contain natural unprocessed nutrients. You could use 'Age Old Organics', 'Thrive Alive', bone meal, organic tea fertilizers, guano, etc.

[dude0]

Ok cool, all those fertilizers you mentioned though aren't available in the UK, well they probably are but called something different...
I found this on ebay... http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&category=42356&item=4363611133

/Dont mknow if it the same, if not what UK sites can I get it from?

[dude0]

Ok i've found products from hesi, they seem pretty good & popular, but I haven't got money for all of em, so which ones can i make do without?

see pic..

[Zandor]

If you only have money for one try one of the many brands that are all in one for grow. Then an all in one for bloom. Only 2 bottles plus Ph up and Down. General Hydroponics, Advances Nutrients all have some you can use.

Peace

[dude0]

Ok thanks for all the help guys, appreciate it.
I realsied that I have fertiliser in my soil, im using Bio Biz Soil....


Bio-Biz is an extremely high quality fermented organic compost for growers who donâ??t want to mess about adding liquid fertilisers - itâ??s all inside the compost, just add water for fantastic results. Add a bloom fertiliser when plants show signs of heavy flowering. Contains a careful blend of perlite, worm castings, peat, top soil and organic fertilizer.

So why am I getting yellow leaves on a 2 week old plant?... I understand that some leaves will die & drop off but I thought that was in a later stage of growth.

Im using Nirvana Top 44 seeds & 2 weeks since germination they are just 1 1/2 inch high?

Please tell me if this is normal, thanks.

That would of helped from the beggining. From what he described, it was either a mag or nitrogen definciency with no mention of age. A plant can become deficient under any circumstance, including nute lockouts, not just double or triple harvesting or extended life. Plus I need to stop smoking before I post.

[dude0]

I heard you can chop away the yellow stuff to stop spreading.... ok to do this or just leave it natural?

[Zandor]

if itâ??s all yellow then it no longer produces chlorophyll and is useless to the plant so you can cut it off.

hi tera vega and teraflores is a good first time f.lizer but don forget your pk 13-14 before harvest

[phillykid420]

The plant has used up the nutrients stored as a seedling and now needs to be fertilized. Use 1/4 str and work your way up as the plant gets bigger. The cotlydons are supposed to turn yellow and die out, that's where the energy is stored to get the plant going. It might also be some overwatering since it seems kinda small to be turning yellow already, but the plant might be a heavy feeder.

[dude0]

Ok cool. How much should I be watering? & how often?
many thanks

[phillykid420]

When they need water. You can't really set a schedule cause there are too many factors. Like how big they are, some strains drink more than others, heat might cause more water to evaporate in some setups, what size pot you have them in etc. You want a good dry period inbetween waterings so the roots get lotsa air. Use the lift test, just pick them up and judge as best you can by weight. you'll develop a feel for what's proper after awhile. Like so many things in life, growing is part science part art and only experience will teach you everything you need to know.

Learn to recognize the first signs of underwater, the droopy somewhat limp fan leaves, and see how long it takes, then water 1 day before they get like that. New growers usually over do everything, nutes, water etc. More is not better in this case.

[dude0]

Ok thanks for the advice. I water everyday & the 6 plants looks healthy, 1 plant does have leaves like claws, i think i have over-watered that one, no to worry though, il just give it less water on the next feeding.

[phillykid420]

Everyday is a bit excessive unless they really suck that much water out of the medium. Get a pot, the same size as the ones you're growing in, fill it with the same dry soil mix you use, pick it up, that is what they should feel like before watering again. They'll obviously be a little heavier cause the plant has weight to it, but you get the idea. I usually aim for 3 times a week, 2 times plain water and 1 time feed. But again, I don't set a real schedule. If you really have to water everyday cause they're drinking that much water than it's time for a transplant to a bigger pot.

peace and good luck

[dude0]

Ok cheers, when I water everyday, I just give them 50-70ml. my pot is 10 litres, i water when the light is off for 4hrs also. I watched this video... Top quality home growing & this dude waters his plants with 200ML a day. If anybody wants too, i can send them the video though msn... [email protected]

Some fish emulsion would help you out a lot with your yellow leaves, it's organic so it won't burn the plants easily, and high in Nitrogen: 5-1-1

Hope this helps
