Thanks Grasshopper

what's your npk ratio?

pics??? more then likely nitrogen deff but could be ph... wait a day or 2 and see how they r... in soil it takes lke 72hrs to notice a difference, hydro 24hrs... dont add more jus yet... thats the prob with soil, ppl think it needs this so the add it and then they think its not enuff so they add more.. then sumthin else happens(most likely burn) and then they start to add more shit to help it... by the time they know it, its toxic soil and soil isnt fun to flush

edit... i jus reread ur thing.. over 7 in ur ph??? how much over??? 7.8 should be max otherwise it will lock out nutes such as nitrogen... read my above, ull give it more but since the ph is off its not taking it in no matter how much u feed it... next thing u know its toxic.. i suggest flushing plant well with ph water at about 5.5... test ur run off and see how high it is after that good flush... and go from there

could be ph but i have vegged plants with ph of 8.3 without any lock outs but that could be it. He might just not be feeding them enough

did a little research on your food and i'm guessing you have a ph problem, if your doing hydro your ph should be around 5.8

dont get me wrong, more then 7.8 is doable but if the strain is perticular??? every strain has it own way of growing... and perhaps he didnt feed enuff but who knows.. ide rather see him correct what we know is off ather then him poisioning it with more chems... fix whats broken and go from there

tru dat.......

hydro is 5.8 soil is 6.5... test ur run off... who knows, the ph in ur soil could be off the charts let alone the water ur feeding it... thats y hyro is an ezer way to go.. much ezer to dump ur res and refill it then wonder what the fuk is in ur soil

I just got back and am glad you guys are here to assist. I have water that is 7 b4 I add nutes then its 6.5 - 6.8 with the nutes. I fed at 600 ppm last night. See...the freakin thing is I have all these strains on my first grow. 10 strains that all came as clones. Some look great some have very very slightly burned lower leaf tips...like the ppm was perfect...then there is this high yealding blue cheeze. The guy said this is a high yealding cash crop...perhaps it needs 800 ppm nutes? I also have a super silver haze that is slightly lighter green. The one with yellow leaves is also slightly lighter green. I am going to take pics tonight of some and post them so please check the thread either later tonight or in the morning and give me a few words to help me out. Someday I will be returning the favor to a newbergrower....like myself...shagrin : )

Thanks Thanks Thanks

Oh yea....did I mention that I did not water them soon enough this week. I am trying not to be a rookie and over water.....well I underwatered and some of the plants showed it. It will be every 4 days weather they need it or not..

I will test the runnoff next watering...or should I flood that plant now and measure it? I have a pinpoint ph moniter that is calibrated down to 100th....

thas the thing.. each plant requires diff ppms and diff quanity of each nute... "kiss" keep it simple stupid.. not trying to offend u by saying ur stupid but runnin with a bunch of diff strains as a noob is difficult for those reasons.. also they will all grow at dif heights... next grow focus on 1 or 2 strains and perfect them.... find out what they like... then move to another strain... i have nvr used a ppm mter in my life but i know jus by looking at my gals what is wrong(well for the most part)... ya ur room is full of bomb strains but if u cant grow them , then whats the point??? get experience under ur belt, then come out swinging... not tryin o put u down but its more enjoyable when u understand them like ur kids.. ya dig??

When I feed my veg food, I go for around 1200ppm. You might need to up your feeding

Are you growing in soil? I am growing in ff ocean forrest, roots organic and sunshine mix #4. Some leaf tips burned a tiny bit at 600 ppm.....I cant see doing 1200 when its only my second feeding but I am the new grower in this thread.....grin

Heres some pics of the problem.......and I will post my specs again for all to see.

Plus some pics of my plants that are doing ok. Even though its 10 plants...and my first grow....I think Im doing ok and I am gonna start flowering as soon as I get this plant figured out. I may just start anyway flowering them. They look ready wouldnt ya think?

Thanks....I hope someone happens by here soon to help me fix this sucker.

Grasshopper....peace out

dude, those look great!!! ur nvr gonna get a perfect crop.. the more u stress about lil things like that, the more damage ull do... yellowing leavs is normal in flowering espeacily those old 1s... theres like 10 yellow 1s outts the 1000 green 1s... i thought ur plant was like dieing and dropping leaves fast... ur good to go, do sweat it!

They are not flowering yet.... Im starting them flowering today.

I guess everything was going along to perfect and then the yellow leaves. I guess I did over react...but I was not about to add more nutes or anything like that. I have read to much about newbie growers burning their shit up....not gonna happen to me..knock on wood. Thats how I went to long between waterings also....not wanting to be the newbie and over water...,so what happened.....under water...hehe

Thanks for the help...

They are 1 month old ?... in veg ?....They are looking pretty good man ... BIG and healty .... Hard to tell from the pics due to the light ... But could be N deficient ...But they look pretty big for a month old

I got them on the third last months as clones....I think he took the clones 2 weeks before then so they are 1.5 months old. I have my room dialed in perfect mabey that helps. The temp never sways more then 4 degrees and humidity stays around 40 - 60 %.

ok....Im gonna flower em. I took clones yesterday....only 5 strains this time instead of 10. It will be hard to let all those strains go but I can only keep 15 plants total including babies. I was begging my freind to keep a few mothers in his basement but he doesnt have a permit to grow and is on parol so he was paranoid....dont blame him 1 bit.

The reason I say 3 weeks into veg is thats when my grow room was finished and I transplanted them into pots and fired up my new room and started them to veg in there. That was 3 weeks ago. I have watered the new pots 3 times.

Promix........... But i know that ff has nutes in it already so you might not wanna go that high. But depending on the size and age of your ladies they might have depleted all food from soil.
