nute burned leaves?

[electric-monk]

my plants are starting to show some damage and i thought that i'd get a prognosis from the pros....
I'm thinking that i may over fertilized, but i've been using no more the 50% recommended amount (10 drops per litre) and have only been on the ferts for 5 waters. (approx twice a week)

the pics are of two different plants, i had thought that perhaps the big guy got scorched in a recent fan snafu, however now the other leaves are starting to yellow as well.

i'm switching to clean water as of today and need advice as to how i can save em!
thanks

1. brand name of soil ?
3. PH soil runoff?
4. PH of water?
5 brand name of ferts
overwatering can cause yellowing your soil seems to be alot of organic material?

to rule out PH related issues, complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....

Yeah it could be , its from the lights burning the excess nutrients in the leaves.

I beleive this is true , is it not?

[Ganja Guerrilla]

nitrogen is a mobile element, when a plant doesnt get enough of a macro nuterient for whatever reason it can take the nutrient from another part of the plant to continue its growth, it basically feeds upon itself which causes the yellowing

Feed me. what it looks like to mwa.

but I'm a drunk, so??

soil in big guy is 100% miracle grow moisture control (0.18-0.10-0.10)
soil in little guy is 50/50 miracle grow moisture control and miracle gro potting mix (0.14-0.14-0.14)

ferts are miracle gro all purpose (8-7-6); recommends 10 to 20 drops per litre of water, i've been going between 5 and 10.

I don't have a PH kit, looks like i'll need one, are the soil type ones good enough?

soils has got some sizable pieces of wood and apparently contains coconut fibre according to the label....? is this what you mean?

looks like nute burn i have a plant thats got nute burn looks alot like that, unless it could be the light? but im pretty certain its nute burn

[Ganja Guerrilla]

Ive done extensive testing with the mg soils and found that the MG moisture controll is the worst soil they make when it comes to growing weed, that soil either retains too much water or it dries out and actually repells water, the water will run down the sides of the pots and not penetrate to the roots

I suggest you transplant to any soil but miracle grow, youll have a better experience

go to my site see the link below and watch the streaming PH and flushing video....it will help you with the PH issues and what you need

I would also use this Miracle Grow ferts instead

Vegatative cycle fertilizer
Miracle-Gro® Water Soluble All Purpose Plant Food (they make several fertilizers be sure its this one)
http://www.miraclegro.com/index.cfm/...c0236933b0a7a4
Fertilizer Analysis: 24-8-16 with micronutrients
2 level "Teaspoons" per gallon of water, (reduce this by 50% first time application) use this as your water, feed every other watering till flowering

Flowering cycle Fertilizer
I recommend Fertilome, Root Stimulator and plant starter....
the NPK is perfect: 4-10-6
2 teaspoons per gallon of water every other watering........ use this as your water ...discontinue use 3-4 weeks prior to harvest...flush last 2 weeks...I also like to add 1 tablespoon of unsulphured molasses to the last gallon of the flush......thats it no more water .....

thanks for all the help guys,

I got the pH test kit and some aquarium grade phUP and phDown today.

I don't think i'll be needing the uppers... the tap water clocks in at beyond 7.6 I've got three litres of water balanced out, hopefully that will be enough to flush out my plants.

I'll post the results of the run of test once i'm going, but i think i know what the out come ....

I agree completely with the MG soil sucking. One of my plants is def stunted, the roots where concentrated on one side of the pot when i transplanted. I'm going to try an sort out pH first, cause i don't really want to transplant again.

Oh just thought of something, this house has a water softener, the large amount of salt type. Will that adversely effect things?

[Ganja Guerrilla]

water softners are not good they add salts , your tap water is fine you need to just PH down when watering

[electric-monk]

hmm well i'm stumped...

i flushed my plants, both got about 1.5 L of water. The water was on the high side of the pH about 6.6 when i balanced it earlier. water coming out of the pot was initially appearing to be 6.0 (bottom of the scale for my kit)

I took a few measurements as during the flushing process and this seemed to increase. I suppse that means by ferts where super alkaline?

Going to let em be for the next few day and hopefully they'll pick up

thanks again, the video was clutch

[Ganja Guerrilla]

there you go....you found the problem.....good job

acidic PH ....if the water that went was 6.6 and it came out 6.0 your actual soil PH is lower than the 6.0 reading you got because the 6.6 more alkaline water you did the test with actually did some PH correcting as it ran thru the acidic soil

flush those plants till the water runoff is 6.5-6.8 and the last gallon of the flush add 50% strength ferts that have been PH corrected to the 6.5 - 6.8 range

your yellowing should stop and the plants will start to grow

[suspect]

hey electric monk, you listen to Ganja's advice and your buds can look as good as mine do!
hey Ganja, have you seen my WhiteRhino2007 thread yet, you helped me save my plants & now they look fuckin amazing. most of em gotta be at least a .5oz already and theres still 3-4 weeks left.
thanx again Ganja!
