put my mind at ease... please?

as you can see from the pics (below) , i have problems...

Dutch passion: think diffrent
Day, 60 from seed,
germinated in a prop. using paper towls

im using;

400w HPS with reflector in a 1.2 x1.2 x2m tent, extrator fan (not sure of the cfm) and an oscilating fan blowing air through the bottoms of the plants
11ltr pots, with a mix (perlite vermiculite peat moss etc)

air temp, 27-29 C
RH 35-42% (42 being after watering)
PH, is a bit too close to 7

nutrients- biobizz grow, bloom, topmax, also added fismix, calmag and magnesium sulphate where needed (not all at once)
have also been using phos. acid to try and bring the PH down, but is making little or no difference.

there is something i need to do, this much is clear, but i cant seem to work out what, i dont want to try to cure the wrong thing if you know what i mean (eg. i dont want to flush it thinking its burnt when really its over watering) because im not sure they can take much more.

im also pretty sure they have been stunted, as the buds are pretty stubby for a 60 day old auto?

the pics are not great quality, and looking at them, they do look like nut burn... but im person there is enough diffrence to make me doubt. however could someone with the skillz either confirm or tell me im a idiot? cant bare to see em suffer any more

any more info needed, give me a shout

soon to be ex plant A

soon(er) to be ex plant B

I think this is normal at this stage for the bigger fan leaves to start yellowing and fall off, but there will be someone more experienced than me who may think differently

 

[manoadamro]

wheeey see what you did there.... (think different...ly (im so sorry, ive been doing that for weeks))

the leaves on the bud shoots (not sure of the tech term) are starting to go too.

i do hope you're right tho!

I'm only starting my 2n'd grow, definetly don't have so much experience, but in my previous grow I had tons of leaves drying and falling like that on the last part of the budding process, and the buds turned out damn fine. There is also a lifecycle of autos guide somewhere in the forums here which also says that is normal, she's preparing to finish. I think your fine they look verry nice btw

 

[manoadamro]

ahh thanks man, i will search that out for sure!
i was worried they may be a little stunted, but thanks for the feedback man, i feel a little less panicy now haha

"Toward the end of this phase the large primary and smaller secondary fan leaves will begin to turn yellow. This is an indication that the plant is moving toward the end of it's life."

If your pH has been consistently up around 7 that's your problem. With a pH that high your plants aren't properly able to up take P and K, which is showing in the dead ends on your leafs, the yellowing and the small bud size. Given their age and the state of your fan leaves, they probably have about 2 weeks left before they are done. That's not really enough time to get your pH issues resolved to the point where they will have much impact on this grow. I would suggest giving them 1 or 2 more feedings pHed to around 5.8, then switch to plain water to cleanse them before harvest, again pHed low. Your buds should still fatten up a bit more as the plant utilizes the stored energy in the fan leaves.

I just chopped a TD at 92 days and she was green right up till 14 days before i put her on a water diet.Has she thrown any sugar on her yet?hows the trichs look? clear,milky,amber?Looks like alot of white pistils on her buds to me.Almost looks like she's hungry as hell,maybe a deficiency cause by lockout from your ph bumpin 7. I am not the best at identifying a deficiency and thats just my opinion,hopefully Muddy or one of the other guys will swing in and give you there opinion.

LOL,Muddy swooped in while i was typin-your safe!

 

[manoadamro]

yeh man, she's got some tastey tric's on her cant find my scope right now but last i looked they were clear (a couple of days back)

i was worried about the PH problem but i couldnt seem to bring it down
