1st DWC, G13/Haze questions

this is my 3rd grow, my first two were in soil and i did exceptionally well. i wanted to try hydro so i purchased the dual pod DWC system with eight sites on each 10 gallon resevoir. I am growing G13/Haze from Barney's farm they are all clones from the same Mother. they seem to be doing exceptionally well in they're second week of flowering, but some of the leaves are really yellow with dark viens and burnt leaf tips but the plants reach for the light and don't seem to be affected by this discolorization but i can't help but wonder if they are lacking something or if they got too much of something. I am using GH flora grow, micro and bloom and am following the directions to the tee, is there anyone who can tell me how to correct this problem, oh the plants are about 14 inches tall.

whats your ph at??
how much nutes are you givin them??
safe-1-

we shall need more info to help mate.

pics are better it is easier to see the plant cause when you say yellow leaf it could be loads of different things but the way it has turned yellow will help show the problem such as nitrogen deficiency or a pH problem

if it is ph yopu will need it around 6 - 6.3 ish i think i just use malt vinegar for it to raise my tap water and works perfect

thanks for replying, my PH stays between 6.0 and 6.5, right now i am using the transition formula wich is 2-2-2 so i add 2 tspns per gallon of water which is 7 gallons in the resevoir which brings the water about a 1/4 inch above the net pot. they drink it pretty fast everytime usually in about 3 days so i refill with the same strength nutrient solution 2-2-2 usually takes 1 gallon to refill it to the right level. the last 2 times i have only used water because i was afraid of maybe burning them and they are still thriving, in 3 days i will be changing out he resovoir and going to full bloom which is 1-2-3. They also seem to look a little better today so maybe it was nutes, here some pics to give you an idea, if you have any suggestions i am open to all new ideas thanks.

i would say thats just the strain..
lookin good tho i got 1 of them g13 haze seeds might av to get it goin!
good luck

thanks for puttin my mind at ease... yah man if you have this strain and get the strong phenotype you will be very happy, the last harvest was done on Ocean forest soil and and i got 6 1/2 ounces off 3 plants and they were coversed on trichomes so that they looked white also very dense nugs, spiceys piney taste and smell.

just changed resevoir and started full bloom nutes today they are still lokking good, still got lower big fan leaves yellowing and burning on the tips but the plants are still going and starting to flower, they show no signs of stunted growth so u must be right about it being the strain. When i grew it in soil this happened but not as much and it was late in flowering so i don't know.

Lookin good bruva!!
keep it up!

Your water level should be 1"-2" BELOW the bottoms on the net pots. The plants need the air between the roots & the water. You can also rot the roots that way. Give them some room.

mos def... Agreed.

I was at a friends who had one of those 5-gallon buckets with the huge deep black top and it was literally submerged in water. He said he knew what he was doing... I gave him a couple of clones, along with his 1 plant he had going... THEY ALL DIED.

well they drink it down i let them have the room between the pots for about a day and then refill them to a 1/4 above the pot again and they are still thriving and the roots are very healthy, i had read that you should put that space in between the water level and the pots and i tryed that last time and the plants didnt seem to do as well i thought. i'd like to hear more on this because i really don't want to mess this crop up at all.

Well, I don't know what will happen for the long haul. Not sure if it makes the structure of the roots weaker in a hydro system... Meaning, it those thicker roots in the hydroton cubes stay wet, what will happen when they grow tall ?

I was a little worried on my end because after the roots hit the water I took out my water pump completely, against some advice. But I went in there just about everyday and used a turkey-baster and soaked the rockwool cubes, and mine have been growing like crazy every since.

Up to you though... I'm subscribed and I'm very curious to see what happens! Good luck!

ok, i have had a lot of thoughts on the water level situation, and after hearing what you had to say i'd think you were right, however i don't let the water touch the organic plug in the net pot and i'd say the water level just touches the net pot, sorry for the confusion. Everytime i refill the resevoir though, they drink it back down fast so during this time they are getting more and more air flow between everything right ? I thought the idea of DWC was to allow the bubbles from the air stones to splash up and over the root zone. I have had minor leaf discolorization due to something that was wrong but it worked it self out and the plants still seem to be going strong. Any suggestion or questions you have i will be happy to answer, here are the pics from today which is the beginnning of wee 4 in flowering.

check out the pics and let me know i just don't want to do something wrong and lose them, but like i said they are going strong, i posted another reply on here

Hope you enjoy the new pics I just started using kool bloom this week and i can already see a difference in just a fews days of using it.

Hey man looking good OG. Curious where ur PH and PPM levels are..Very critical right now to keep ur ph as close to 5.8 as possible..otherwise ur going to end up with some type of lockout or deficiency of some type related to a lockout.
Looks like u had or have been having PH issues.. for the most part bro the grow looks dmn good.. just thought id throw a little input so u can get the best yield at harvest time...
Im also using KB..Nothing like it to harden buds and pack wieght on um.. very critical again to make sure u keep ur ph proper there too.. KB is high in P/K and high and low PH will cause these nutrients to bind with other nutrients causing problems in the long run.
Bottom line bro long as u keep ur PH steady at all times it keeps the uptake of the actual food ur putting in the res readily available to the plants..
It aint doing shit if ur plants cant use it and PH is the key with nutes.
Might wanna look at some diamond nectar ( Fulvic Acid) now.. Its gonna help ur flowers all the more with the steady uptake of the P/K as well.. Optimal for plants soaking in water man..
Do it up bro..
Good shit.

Thanks for the info bro. the PH usually stays between 6.0 and 6.5, i think i'll lower it just a tad and see what happens since you said it should be closer to 5.8. In all honesty i have no idea what my PPM is, i don't have a meter yet. i've been using full bloom strength solution to refill both resevoirs and they don't quite refill them all the way so i dilute it little more with some fresh water. I do this at the end of every third day and change the resevoir every two weeks. I've heard of that diamond nectur i think i'll try that also. Thanks !
