Inherited and in need of a little help

[Ceese]

First the important stuff.

What type of medium; soil

What brand and type of soil? It started out in Miracle grow time release potting soil but just after i got it, it started to get some nute burn so, at about 6 weeks from seed, i transplanted into FFOF

Indoors or outdoors? Indoors

What strain? Bagseed

How old are the plants?10 to 11 weeks from seed

What type of lights and how many watts?CFL 3 of them 27 watt true wattage

How far from the lights? 3 to 4 inches

What, how much and when was it fed? NPK? 6 days ago 16-18ozs of plain water. then i noticed an older leaf was beginning to yellow. that was 4 days ago (3.5 weeks after transplant into FFOF) the leaf got crispy and bent under. The next morning more leaves appeared to start yellowing so I mixed up a gallon of water with about .75tsp of Fox Farm Grow Big and gave it about 10 ozs 2 days after the most recent watering. The next day another older leaf curled under and got crispy. They eventually brown from the center out and become useless so i cut them off.

What are the temps and humidity in the room? 87 degrees at the leaves closest to the lights. 35 to 40% humidity

What size pots? 3.5 ish gallons

Any bugs? Look real close. a few gnats from time to time

Any other pertinent info? she (hopefully) is really small. Very tight with lots of growth but smaller than I have come to expect at this point. I'm growing it LST so in the pictures you will notice she is bent over to the left. This is very much on purpose. I have my suspicions but i'll keep them to myself for the time being so as not to influence your judgment. Thank you so much in advance for your time and help.

Also the plant was started on an 18/6 light schedule. Recently (after i noticed the yellowing/browning but before it escalated) I switched it over to 24/0. it's been 4 days at 24/0 and i'm afraid to switch back as i don't want to induce flowering. It's too small to flower unless i don't have a choice.

[Ceese]

does anyone know what this is?.. it's a little more yellow this morning..... help.

[Ceese]

bump. Anyone out there got even a hint for me? please?

[zygote]

dude i'm not sure. It should be much larger at 11 weeks. How often are you watering? What's your waters ph?

[Ceese]

Once every 5 days or so. When it feels dry about an inch deep. ph with nutes is reading 6.5ish.

[Ceese]

is it possible that when i transplanted from the MG that one of those fert balls stuck and didn't pop for 5 weeks? If that happened this could be a nute burn right?

[Ceese]

BTW it would be just short of a foot if it were straight. The new growth looks really happy and there are many new leaves popping from where i removed damaged ones but there is still yellowing/browning.

[Ceese]

bump, please help.

[itguy]

It looks overwatered and like you may have had a pH problem at point. IMO water with water only for the next 2-3 waterings and see what happens. If the new growth looks good, it's often fine it just takes awhile to recover

[Ceese]

thanks, itguy.

Looks like a little fert burn maybe. Not a big deal. Its a little hot in there to at 87 degrees F too.

[Ceese]

Thanks smknVTECH. I think a fert ball from the miracle grow may have hung on during transplant and when i saw it yellow a bit i freaked out and gave it some grow big, making things worse. i appreciate the help.
