Hi, new to the site so hi to everyone!!

I need some help with my 4 babies, i am using a nft system, switched to 12/12 a day ago. I am using vita link nutes. I am not sure what the problem is but would be gratefull if anyone can help me.
The tips of the leaves have gone light green/white, some leaves gone more yellow.

I'am not sure what's goin on but I like to say very nice garden bro:aok:
Just stick around someone will come by that knows what's goin on
*EDIT*
Found some pictures that match your plants, So it looks like you either have magnesium deficiency or deficiencies in vegetative growth.

I think you have a sulfur or nitrogen problem. Have you tested your fluid?
Do you have a pH and EC device?

 

[tokalicious]

Hi, yes i have both.The ec (cf) is running at 18 and ph at 6, although the ph does keep rising to 6.2 - 6.4. i bring it back down to 5.9 daily.

Looks like a nute def. to me....are you giving them the nutes at full strength? Also now that you have swithed your lighting to a flowering schedule (12/12) you won't have to water them as often, because the lights are'nt on all day and all night drying out your grow medium as much. Look under the "sick plants" section in the main forum, I believe it was Mutt that had some very informative posts on this very subject. Well, GL on your crop, and hope I was able to help or at least point you in the right direction bro.

Thanks kaptain, i am using a nft system so its not a watering problem. i will have a look at the sick plants posts.

normal..

you you will lose fan leaves during flower..

by the time you are ready to harvest. you will have lost 90% of
all your leaves..

if you like add a little Nitrogen nutes you used during veg..

 

[tokalicious]

thanks, should i raise the nutrient level?

 

[MrPuffAlot]

no dont raise NUTE level.. Just add a little of VEG NUTE 1/4 strength

 

[laylow6988]

Uhmmm... I don't know if I'd do that yet. Anybody think about it's going into flowering? I could understand giving them maybe one 1/4 doze veg nutes.... but if he is putting them into flower I would think to just go ahead and start fertilizing for flowering at this point. I've heard it really helps to start the bloomin nutes a week or even two before you initiate a 12/12 photoperiod. I'm not sayin I'm right, just giving my opinion. And make sure to give them a good fertilizer with trace elements so that this does not get worse. I wouldn't rely on my advise, see what a few more people think if I might be on to something here. Good luck! They look great.

just a fast fly by post.....



plants are starving for food.... you said 1 day into 12/12 so the will need N for 2 weeks yet to get thru the stretch and then again midway flower....

hit them up with some food and bring PH down to 5.3 and let it go back up to 6.3 so they will be able to uptake more....

Basic cheat sheet:
Ec goes up, PH goes down=plants require less nutes.
Ec goes down, PH goes up=Plants require more nutes
Ec stable, PH goes up=Equilibrium=Good thang.

I allways go 50/50 on veg/bloom nutes first 2 weeks into flower


nice plants mang just need a bit of food like
