Leaves turning yellow. Please diagnose. Lots of pics.

vegging fox farm nuts.

following the feeding sched. week 4:
3 - grow big
.25 open sesame
.5 kangaroots

1000w hps

1.5 gal pots.

miracle grow soil



some leaf edges are curling up and turning brown, and from what i searched, im
led to believe that its nut burn.

the yellowing leaves im leaning towards pots to small

any input helps, thanks in advance.

update, replanted and watered the 1.5 gal plants to 3 gal. hoping to solve the problem.

thanks for all the help.

bump............

looks like u got a nute burn and deficiency along with over/underwatering. how much water do you give them and how often and whats the ph of the water because if the ph is too low or too high your plant wont be able to absorb certain nutrients and it will cause them to become deficient.

i give em water on wednesday and saturday every week. i dont ever check the ph because a friend of mine who also grows told me he checked the tap water, after he let it sit all night, and it was about perfect. im gonna buy one.

Yea ph usually isn't that bad in tap water depending on where you live. watering schedule seems good so you should just follow up with the ph meter and give 1/2 or 1/4 str nutes for the time being to see if thats the problem

Still check the ph in tap water. Mine is at 7 so I always have to drop it down.
