Confusion over yellowing leaves?HELP!...S.O.S!!!

here is some pics of my plant i am using three 23 watt 2700k cfl's and some u-tube flourescents up until two days ago i was using 2 13 watt 6500 k cfls and the two u- tubes I just noticed this in the last 8 hours (the heinous yellowing!) the rest of her looks a-okay like not a discolored leaf on'er! i added a little fert 7days ago just a little though not even 1 eighth a teaspoon to a litre!! help she has been thru frost and survived (I lost my main kola but hey shes alive!) i'm using soil and water her 500ml of water usually once a day unless she looks really wet then i wait til the next day i'm also using a bottle of sugar water and yeast to create co2 (no i don't pour it in the soil it sits beside the plant in a box i made for her and the heat in the room is about 30-40 degrees celsius maybe higher but not lower i can't afford a temp. gage/gun(24-7) and i have a fan blowing at her all day and night so yeah...um, HELP!!!

Watering everyday in soil is wrong, temps are by far too high and co2 will make no difference to your plants whatsoever so discontinue that. Get better lights and setup with decent inline fan for ventilation and use 40%perlite in your soil. That said you cant do nothing about it now and temps and watering are killing them quick.

Personally i make bread and the yeast i use barely makes enough Co2 to rise a loaf let alone provide plants with a decent source plus plants really have to be very healthy to benifit from Co2. Peace

How long you been on 12 12? And definitely dont water everyday. what size pots?

12 /12 = 37days...pot 8inches wide by 10inches length i just switched the heat to this temperature a week ago and i already have a peat moss perilite organic compost mix!

thank you for you

Why did you wait to switch the color of your bulbs? Should go to 2700 when you started 12/12. Looks like maybe a ph issue. The nutes you added dont look like theyre getting to the leaves. PH lockout maybe.

how would i remedy a ph lockout this all started after i switched the lights? THanks you are very helpful that other guy tho...yeesh ! this is only happening to like 1% of the leaves the rest of the plant looks healthy soil is dry about a finger down in! I know about switching the bulbs but I had it outside and thought i could finish it there but frost changed all that and i wasn't prepared...but now i have thje right lights!

yeah i grew this plant from a seedling to what it is today on cfl's 2 15watt ones! you dont care if this plant (living organism) lives or dies it might not be concious in the same manner as you are but it still deserves a chance to live...whatever

I wouldnt, main focus first would be temps. So you think you got pH problems then flush but if temps arent good to start with i.e. 25c max then it dont matter because you will never solve initial problems. No one want to deal with the problems at hand and seems rather too easy to say pH or cal/mag. When temps and ventilation plus heat from bulbs is all cool only then could you consider a pH problem which is not really pH but more you probably overferted and all the salts from the built up ferts the plant hasnt had a chance to eat are turning the soil acidic. Most shop bought soil is spot on with some perlite mixed in so dont be thinking bad soil rather you added too many ferts and messed the lovely soil up.

Still at 30 to 40c id invest in sorting temps first or every grow will always fail. Peace

thanks I corrected the heat issues down to 22c and stopped the watering soil is dry but the yellowing is still spreading shes gonna die oh man shit i'm killing her this all started when i switched lights i'm switchin 'em back! Shit dude help me I don't even smoke weed I just like plants I don't want her to die what do I do Oh man...

How can i tell if the soil is acidic?

I only ferted 7 times her whole life she hatched june and I always gave her about 1 third of what the directions said the ferts 3.37.24 its got Ca Mo andNa in it too I also mixed in some magnesium just for good measure.

Hey shes in an 8 inch pot now, if I transplant her into a five gallon pot carfully mind you and put new soil around her then water her a bit for a few days would that not dilute the fert buildup in the soil? just an ideas.

sje needs some N...i am not ruling out the latter either, but she does need N if it was me, i would...just as kingrow suggested, make sure the environment is on, and then look into PH or lockout...but say your environment is good...i would flush with 1/4 strength veg nutrients, then let the soil dry out, then continue normal feedings...i can tell by the NPK ratio u posted that N is probably the root cause of the yellowing.

Could be that you are feeding too much potassium and phosphorous, that fert is like a flowering booster not flowering fert, 2-8-6 or 4:8:6 would be better than flowering.

Totally down with this, would be the best way to correct this nutrient problem. Keep on monitoring the environment too dude just because it was off in the first place, never get complacent.

Sometimes it is the way that we kill plants, germinate another and make changes for the next grow, i too love growing plants even the non smokable kind, growing indoor tomatos will give you excellent practice for weed. You have made it to this stage so a good grow so far, normally confident that growers will go on to have better grows the next time round so use this as a good practice and hope it yeilds some smoke which it should. Flush and re-apply veg nutes or somthing 8-6-4 NPK or even 7-4-5 would do but somthing aimed at a vegetative stage.

Hope the plant pulls through and things go well. Peace
