Nute Burn or Heat Stress or other?

[ggmallow]

Hello GrassCity. After looking at the plant abuse charts and other information I am having a little trouble deciding if this is nutrient burn or heat stress or something else that I didn't pick up on. Here is the common info I need to present

What type of medium; soil or hydro? Soil

What brand and type of soil? Unknown :-(

Indoors or outdoors? Indoors

What strain? Blueberry

How old are the plants? Aproximately 5 weeks into flowering.

What type of lights and how many watts? 4x 26watt CFL

How far from the lights? About 2 inches maybe a little more(as close as I could get where it didnt seem as if it would burn the plant)

What, how much and when was it fed? NPK? I am using Jamaican Bat Guano with ratings of 1-10-.02, I mix according to the bag which is 3 table spoons per gallon of water. I usually water until I get slight flow from my pots drains. It was last fed this morning, the problem was around slightly before this watering, before it has been aproxiametly 1 and half weeks since it was last gave any nutrients.

What is the medium/runoff pH? 6.0

What are the temps and humidity in the room? Currently they are at 76 with humidity of 34%. I know this doesnt show heat stress but one day I came home and my AC was turned off and the temps rised into mid 90s and possibly a max of 98.

What size pots? Half gallon

Any bugs? Look real close. No bugs

Any other pertinent info? I really wish I could transplant this because I am aware that Half Gallon is not efficient but I wasn't positive on if it would disturb or hurt the flowering. Was I right to assume this? Another thing since this problem has appeared my plants growth has accelerated I was just worried being so far in flowering that it would die.
Here below is some pictures of the problem, sorry for the lack of quality but all I own is a cell phone camera.

i am grwoing w.w. and something else. i just plucked 2 w.w., and that looks similiar to what mine were doing, around the same week and it seemed to get worse as weeks went by until all the non bud leaves completely yellowed and fell off or got plucked. Some body told me that the later into flowering they get, the plant is sucking out all it can get from the leaves to put all its energy into the flowers, so it msy be naterual and possibly a good sign. My grow is in hydro though, so there may be a diference. If i am wrong, sorry for that bad info, but i could be right.

I have heard similar I am just checking up you know, concerned farmer. It could be why my buds are dramatically changing.

What makes me think it's not natural is because it's the top. Normally your lower fan leaves yellow and fall off because they're not needed since they're not catching any light so the plant drops em so it can put energy into the buds. The top leaves however, are still important for photosynthesis.

Try giving it a flush and water with little less nuts. And if it is natural then it won't be harmful anyways. Better safe than sorry.

Holy shit i'm really high so I didn't catch everything you said the first time but half o gal is way to small. I'm really not sure if the roots still develop much at this point but that motherfucker is skinny

Actually considering when flowering is when they rocket up the roots deff must grow. So yes transplant asap so the thing won't be so rootbound. It might show a little shock but growth will resume and your yield wont suck.

Yeah I am just a little nervous, Ive transplanted but only small little plants. Anybody else think I should go ahead and transplant?

[smokyeyes]

yes do it now youll like the results half gallon is good for 3 weeks a month tops figure 1 gallon per one square foot of growth

I went out and bought me a much larger pot today which is 4 gallons. While I was at the store for the transplant I purchased fox farms ocean forest as my new soil Wohoo!(Finally I know what it is in) Pretty easy and now lets wait and see what happens.
