so this is my first grow ever. i have 4 blueberry kush (autos) and one creme caramel (not auto). everything was going well all through flowering but now they seem pretty late in and i am starting to have problems that i can't seem to find answers for. the main problem is the older leaves yellowing/browning number 6.jpg number4.jpg and in some cases dying number2.jpg. the newer leaves seem ok at the moment.number 5.jpg

the only things i can see that resemble this are; 1. cal/mag deficiency 2. sulphur deficiency 3. lack of light very possible as the weather has been bad for a whole week now)
i used plant magics oldtimer on them when in veg state and switched over to platinum when they began flowering. the CC is has not begun to flower but is having the same leaf browing issues that the others are.

also,one of the BBK's is really small compared to the rest, it's also farther along than the rest number1.jpg , does this happen often?

i really just want to know what the leaf problem is but any other advice would be invaluable, i live in a place where it's so hard to buy that my year is riding on this. i made a couple of other threads earlier in the grow and only got one reply so would be great if a few of you could help me out, even if you can give an idea on how close they look to harvest (from the close up pic)number 3.jpg

container are too small. are they rootbound? if so, they've probably eaten everything in the soil, a transplant will probably breath some new life into them.

bad weather/lack of light wouldn't do this.

some looks like Calcium deficiency. lower yellow leaves have no green veins so it's not Mg def.

Sulfur def. starts at the top of the plant so it is not that.

Ph of soil is probably not stable, which is what is leading to your deficiency.

If they are rootbound, transplant would be your best option and make sure the new soil is of good quality and they should recover. if you feel they are too far into flower for transplant, then maybe try topdressing some oyster shell powder (or make your own shell powder from local shells by smashing them up and try dissolving some into water for immediate availability to the plant.

i've just noticed in the worst effected plants that there is some sort of larvae wriggling about in the soil, i'm guessing thats pretty bad :(
