Week 7 yellow leafs - Need help !!

[DarthMaul]

Hello,

Autoextreme Dutch passion
70-75F
40-50% RH
20% (of my 10L pot) watering every 5-7 days.

Tried flushing plant after yellowing of leafs
Tried epsom salt
Tried adding molasses
Gave small 1/3 strength solution no recovery...
Plant is very underdeveloped and weak
All failed dunno what to do anymore please help.

Edit: Autopic poster didn't work for easier view press here : http://share.pho.to/5ehU3


What type of medium; soil or hydro? Soil
What brand and type of soil? No brand since in the country im in there is just normal organic soil none of the mircale grows etc you guys have.
Indoors or outdoors? indoor
What strain? Autoflower Autoextreme
How old are the plants? 7 weeks old
What type of lights and how many watts? 2x125 W 6300K 3x105W 2700K CFL
How far from the lights? Close as seen in pics
What is your watering frequency and source of water? Every 5-7 days 20% of 10L pot
What, how much and when was it fed? NPK? Feed Biogrow 3-0-8 Biobloom 1-2-2 and Topmax 0.2-0.-0.1, Molasses 1tbp per galon
What is the medium/runoff pH and PPM if in hydro? didnt check fed ph water between 6-7
What are the temps and humidity in the room? 70-75F
What size pots? 10L
Any bugs? Look real close. There were killed whiteflies with traps and neem oil
Any other pertinent info? I only feed biogrow because plant didnt stretch and is very underdeveloped. I have a 2nd plant 15L is doing extremely well

I take it your nute are organic so you shouldn't have lockout.Try and keep your ph between 6 and 6.5.I would keep feeding veg and flower nutes but go full strength and get some cal/mag .Make sure you water entire pot until you get runoff.

At 7 weeks, I would also recommend giving cal/mag as well.

Is there a organic cal/mag you can advice me? Thanks for responses will go full strength on next feed or this feed?

I'm not an organic grower but I've read Epsom salt (found at the grocery store, used to soak aches and pains) is considered organic. It's magnesium. While waiting for a bottled calmag supplement you could add 1 to 1-1/2 tsp per gallon of water. It's relatively fast acting.

You can also foliar feed 1/4 tsp in a pint spray bottle. I believe this is even faster acting and is especially useful if you have a ph problem hindering uptake through the roots. If you spray, try to get the undersides of the leaves. Don't put under bright lights until droplets on the top-side evaporate. If your plants are budding, be sensitive to your relative humidity and potential for mold (use a fan to help the buds dry, or don't even spray if your RH is extremely high).

Can epsom salt be feed directly to the soil with water?
Interesting... I thought its only possible foilar?
Does anyone know maybe?

Yes it can Cyklos.

Good luck.

:smoke: Cyclos- ...Sorry to see you back again, mate... a rough go with this girl so far, huh... she looks pretty worked over at this point, and I know you've been really trying! I forget, what brought you here last time, same plants? Similar issues? ... Hmmm, when multiple problems get this far advanced, it's hard to say what to do, and pick apart what's what- LOL! It's a tangle, of sorts.... I see Ca and Mg defc. still, and maybe P as well,... overall nute' hungry, really, as your fertilizers are very mild, and too low in P, I believe,.... More importantly, we have no idea what your soil pH is, and I have serious suspicions there as well! As such, flushing may have done more harm than good, (hard on the roots), especially with a plant already hurting for more nutrition... I see you've been adding molasses and epsoms, which should have covered your Mg needs well, and helped with the Ca (from the molasses), yet she still looks starved for them which makes me think potential lockout; How much epsom salts are you diluting? An initial treatment at 1 tsp./gal in soil is fine, but not every time you fertilize,...salt build-up is the potential problem with this... I'm not sure what's best here Cyclos, it's kinda you call whether to try and ride her hard, live or die, and get what you can from her,..clearly, yield would be poor no matter what, quality may be lessened by the trauma,... Run your nute's, grow and bloom combined, 1/2 strength grow, full strength bloom,... but this low P value will negatively impact blooming,.... I realize you're in a place where availability of products is very limited.... seriously consider a new line of fertilizers next time, if you can! **** You could try foliar spraying, ..(did we talk about this already?), it's the fastest way into the plant, and bypasses the roots/soil in case there's a problem down there,... Let us know, okay?

The only warning I've read is that it is "salt," over time it could build up an unhealthy salt level in your soil. I've read some people who say they give 1/4 tsp/gallon Epsom in any water that hits their soil (from veg through bloom). Others warn about the "salt" nature of Epsom. I don't know if the preventative users give enough water to have substantial 30% runoff, perhaps reducing buildup. But, definitely in response to a deficiency it shouldn't be a problem. Especially if you do some healthy runoff in subsequent feed/waterings.

Hang in there. My first 2 autoflowers were problem-free, 6 ounces (dry) harvested. My third has been serious problems (acidic soil). I've nursed her through with foliar feeding epsom salt with Alaska Kelp and Alaska Morbloom (1/2 tsp / pint of each). She looks like hell, but I'll get 2-3 ounces anyway.

Hi again Weira, listen only one of them is doing bad the other one is doing really well. See pictures here: http://share.pho.to/5f2Rv

I will try to feed her more and do the live or die technique... I hope I will get atleast 20 grams or so out of her. She pisses me off !!! Weakling plant xD Look at the difference.. my other plant is triple the size LOL.

I only foilar sprayed epsom since I didn't know that it is possible to feed it to the plant... Maybe ill try 1/4 tbs today with molasses and full strength bloom since i flushed all the nuts out recently.
Problem is i only wanna grow organic and dont want to add any chemical fertilizers... Why is Biobizz not good? They gave me 2.5 ounces per plant last grow!!!
