2 problems one plant which cure ?

i have had a couple of problems with my plant one is that one of the leaves near the top are yellowing near the center, and towards the bottom of the plant the leaves are yellowing slowly up the plant. it is just starting to bud.

by the time you read this there should be pics in my gallery.

any help would be appreciated ad

it sounds like they need some bud boost or something. Did you give them some after the long dark period as you switched to 12 12? are these yellowing leaves receiving enough light?

yea they are defo getting enough light they could do with some bud fert tho its just that the other leaves at the top look burned as well as a couple of the tips

First, if you have burned leaf tips, you are over fertilzing. The yellow in the centers is normal. That's the start of the budding cycle. It's actually my favorite time with the plant. I think its the most beautiful then. Well ... then there's full bloom and all the dripping crystals too ... *lol*

1st of all how old are your plants???
2nd what are u using soil or hydro????
3rd whats ur light wattage????

cause from what u discribed it sounds like a normal Nitrogen deficiency

right there are some pics in my gallery of the leaf that is fading to yellow and the leaf that has a yellow patch in the center.
they are 2 months approx poss 3 about 2 weeks into budding maby 3
i am using soil and a 400w hps
it is also looking very droopy since i gave it a misting with some mild nitrogen fert.

i really dont want my baby to be stressed now she is budding. I am down to one female out of 6 plants there are 2 10 inch clones in the bud space 2 tho

right the burned tips are very mild and i am not worried about them for the moment. the yellowing in the center looks more like a dying yellow than any good kind of yellow. the leaves at the bottom that are yellowing do look like nitrogen deficient leaves though.
i gave it a misting with some very mild (mostly nitrogen) fert. and this just made the plant droop lots
she is about 2 weeks into flower poss 3 and i am growing in soil with a 400 w hps

i really dont want her to get stressed at this stage england is dry i would like to sit on an oz and smoke it with the satisfaction that i have grown it.

there are a couple more clones in the space but other than that i only have the one plant (fucking males)

one of you experienced people say what you would do and i will not hold it against you if the plant goes tits up

there are pics in my gallery

lol i thought my post got lost you get the same one and then the same one again double discription. hope it helps

get the pics in the thread its easier then to be back and forth to give u an answer dude....

burned tips isnt always nute burn. if you use tap water then the chlorine and fluoride in the water can burn the tips slightly.

You said you were defo getting enough light. does your hand feel uncomfortable when you place it over the tops of the plants?

nope its fine my light is on the side so the plant is even all the way up (i wanted to try this) it seems to give incredibly bushy plants

i am not worried about the yellowing at the bottom that just defieciencys the one i am worried about is the yellow patches in the center of the leaves near the top of the plant also the leaves near the top are starting to curl in on themselves (on the underside) if this gives any
help on the diagnosis

thanks a lot for all of your help lads

sounds like too much nutes. On your next couple of feeds just try plain water.

okies i will give it a shot

thanks peeps

when only the top leafs start to curl thats an indicator for heat stress...

cool i will get another fan in there and see what happens

thanks again ad

Ok Folks,
You are dealing with stress! Yes nutes can cause this as well as heat! But guess what? Your Ph level is out of wack! Cannabis needs a Ph level between 6.1 - 6.2. Had better check Ph before changing nutes levels. I've been in this business of growing for more than 20 years and time and time again people don't ever bother with Ph levels. If Ph is out of wack your roots will get little or no nutes to the rest of the plant, causing spotting from top of plant and working it's way down over time! So my suggestion is check your Ph level first!

Also forgot to mention the temp of your roots should be between 64 degrees (F) to 68 Degrees (F) for the most healthiest root system. And yes curling is an indication of heat stress, but spotting occurs from to much nutes or Ph balance being out of wack!

what is there around the house that i can use to lower ph then i have lime but i was using lemon juice to lower. is that ok just to double check i heard that it was ok from a different site id just like to double check my facts
