random yellowing (pics)

[Unsane]

This plant was doing great and woke up this morning to find out theres some yellowing happening to random leaves.. on old and new growth... How can i heal my baby back to proper health? Also when i water it, it gets all perky and pretty for about a day and then starts to droop again, is this normal? i have been watering her every 5ish days so far and she has been given a 1/4 strenght feeding of 20-20-20 10 days ago.

The strain is unknown
temp 30ºC
Hum 44%
soil: Pro-Mix Ultimate organic mix
Lighting: 4x23w - 1x42w CFL

Thanks for all inputs!!

You got nute burn, flush them with 5 times the volume of your pot, then water for 1-2 weeks until they start growing at a good pace again. In the future i would either buy a PPM meter so your not guessing with the nutrients, or flush your plants every week so you dont have nutrient buildup, cheers

could be nute burn, but that massive yellowing appeared overnight?
watering every 5 days could be ok, but how large is your pot?

It's a 1 gallon pot.
And it happend maybe in the space of 24hours.

Its under 18-6 light also i forgot to mention.

seems hella fast, what did you give them 24 hours prior to noticing the damage?

edited for being blind.

how much water every 5 days?

when i fertalized my plants i had organic soil with nutes in it and my ppm was at 4500! you are probably way over too, you want it to be around 600 for your plant, maybe less. I say flush!

It's hard to tell from the pics, they're kind of dark (tell me you turned off the lights to take the pic? otherwise you definitely need more light!!)

Hate to say it, but it looks a bit like a mosaic virus to me.

the plant is far from the lights in the pics.

And thanks for all the inputs so far guys! really apreciated!

mosaic virus would be the worst case, screwed if that happens
i think there was a mosaic case here a month back or so, don't think you've got mosaic, hope not
someone brought up watering, have you been watering so there is a good amount of outflow, say at least 10% of the water put in?

Yep, her watterings are good. I will be flushing her tonight and i'll update this thread as it goes along. Thanks again for all that replied and keep the comments coming you can never learn enough =)

24h later its lookin' ok so far.. the plant aint dead so its a good sign i didnt mess up the flush haha. The 2 effected leaves have gotten more yellow but i dont notice any spreading to other leaves so far. I'll put up some up to date pics tonight.

Well here are some new pics from today, took her out of the cab to take a few shots sorry for the delay but here they are.. One of the leaves has a burn hole or something.. maybe someone can clarify what it is, its not pests i have looked at allmost every area with my detached camera lens manually.

Thanks again!!

Plant's color looks pretty good. Seems like the flush may have helped. The hole doesn't look too much like bug, from the nute/ph issue more likely. Bit stretchy, not sure if you've added any more light.

The plant was stretched from the beginning its a clone that was given to me and the batch was kept under cheap fluos. My grow cab has around 180ish w's of CFL wrapped around the plant for now and i'm still debating on if i should go for a 150w hps or some 125w CFLs since my space isnt that big and heat could be an issue. 3f wide, 4f tall, 2f deep. I noticed the side of the leaves curled upwards after the flush.. i'm guessing its becasue of the amount of water and nothing i should be worried about right?

Well that is that and like i said i'll try to update as it goes. +rep thanks for fast responses =)

this is a pic of the plant when i got it.

180w isn't too bad for one plant
but reflectors(especially good ones) can nearly double the amount of light that the plant will get
it's almost like buying another 180w worth of cfl's, but home made reflectors can be done very cheaply

Yeah i was just thinking about making some reflectors... and i will have to upgrade the lights since i have seedlings popping out also so ya hehe.
