slight yellow leaves any sugestions??

:cool: ok these are in week three of veg and there is a little yellowing of the leaves on the lower nodes any ideas???? i had a ph flux about a week ago for a day or two while i was out of town not to bad tho ....... i am using all holland secret nutes bada bang 5-0-2 bada bing 2-1-7 bada bloom 0-6-4 with liquid karma and some sweet citrus ...... any input would be great .... and stinkyattic i just want to say thanks for spending alot of time helping others it shows of good character:jointsmile::jointsmile::jointsmile:

hey allkillanofilla,
I'm going to guess that since the leaves are a nice green color but you have some tip burn, that you have overferted them. Do you know what the ppm is, which is something you need to watch closely when growing in hydro.

there's a way to grow where you won't experience this kind of problem. there's a way you can prevent this kind of thing from happening and you'll take all the guesswork out of growing. the method is this - don't try to do anything special. just get some Foxfarm Fruit and Flower powdered fert at your grow store and put two cups of it in a five gallon container and mix well, then put your plants in that and just water them when their thirsty. That will solve 99% percent of your feeding issues. You won't have to worry about salt build up. People make too much out of growing. It's just a plant. Don't do anything special and you'll have better grows.

how the hell are they growing in teh rock wool, i tried that crap and all m roots dry rotted. and i cant under stand a bit of that. so i stopped using it.

i have seen the rock wool used a million times so maybe it was just me. how does it work for you man?? and how do u keep them from dieing?

nothing special well durn maybe that's my prob too?

people make growing this plant much harder than it is. just grow it like you would any other plant. You want to use Foxfarm Farm's Fruit and Flower powder fert cuz it's full of bacteria. It is actually the bacteria that break down the fertilizer to molecules plants can take up. Mix it with Foxfarm soil or something similar and it should be all you need as it has much of the micronutes plants need. After that, just give them good water and time to grow. You'll be shocked at how easy it is. It seems like people always want to tweek their plants to make them better. All that does it make things worse.

Wayward, your advice makes no sense in this situation, as the OP is OBVIOUSLY running a fully-hydroponic system, and it also sounds a bit familiar... ???

Killa, np on the help, that's what I'm here for lol.
What pH are you running, and can you get a good check on what it is coming off the slab? Sometimes you will see pH RISE in RW and go out of range. But they look pretty good. IF you are concerned abotu that tip burn, definitely do a complete res change every 2-3 weeks and keep your pH in the range of about 5.8-6.2, and you CAN let it swing up and down within that range- many successful dro-ers do it that way.

What's your water source, pH, and EC numbers out of the tap and also in the res? Are you running by numbers or a set volume based on the mix on the fert package? Sometimes that gives a stronger solution than the plants really want, depending on how 'hungry' that particular strain is.

I am using tap water with a reverse osmosis filter . PH is 5.5 -6.0 never above 6 unless i let it slip for a couple of days. I use a strick nute program from holland secret here is a link for the feeding chart i am using. Also i use liquid karma and sweet citrus from botanicare. One more thing my ppm is at 1246 currently and i am in week three of the nutes

Okay next questions!
-Is that the pH of the reservoir, the runoff off your slab (this is MOST IMPORTANT!!!), or the RO right outta the machine (This is MEANINGLESS until you add your CalMAg and nutes).
-Are you running CalMag? You have to run it with RO water no matter what your system. Add it up to about 200-300 ppm before adding your nutes, THEN check pH, THEN adjust to 5.8-6.0.
-How often do you change out the res? Do you do a complete change or partial? If partial, what is the EC after refilling the water but before adding your nutes?
-Are you running by volume or by the EC numbers (mL per gallon or ppm overall)?

I really suspect that your #1 problem is a Calcium deficiency that is SO EASY to fix just by slapping some CalMag in there on your next res change.
