yellow tops

[Dr. D]

I got some mr nice shit that nearly finished buddin 1 hydro and a few organic. the hydro plants really healthy ( 1st time hydro) but the organics have gone yellow on top, there lush and green under neath. Anyone got any ideas on wot could cause this? They also seem to hav a considerably rreduced yield? peace

 

[Dr. D]

Anyone!!!!!

 

[ezozo]

can you put some pictures ?
It will help ....

what is the distance from the light ?
what fert are you using and how much ?

Il take some pics shortly when the lights come on. The nutes r bio-bizz bloom and top max bloom stimulator 4ml per litre of each at the mo and im gonna start flushin real soon, i didnt get this problem with the hogs i grew last grow, evry thing was done the same. Lights are very close, though I am using a heat shield which I highly recomend as u can get the light loads closer. peace

Hydro just kicks ass thats all. If you start a clone in Hydro and Soil at the same time the Hydro will double the size in the same time compared to soil. Which will in itself out yield soil due to the increased size. The yellowing is not a problem. A lot of plants yellow towards the end of flowering. It comes from a lack of Nitro which the plant takes from the leaves. The Hydro system must maintain the nutes longer than the soil does. Either is acceptable.

Thanx blatant but the yellowing has been there for about 4 weeks. peace

 

[Dr. D]

How do you get ur pics on to ur post? I fucked it up and lost all of wot id written on the post?peace

 

[Guest]

Its not unheard of. I usually go one week into flowering with my grow formulas before I switch to a bloom solution just for this reason. Especially for Sativa dominant strains. Maybe the soil is locking out some Nitro. Whats your TDS?

are the soil plants taller?, closer to the bulb?
maybe they are just a little too close.
without pics it hard to say
N deficiency will manifest itself on the bottom of the plant.
what you are describing, with the few details you have provided, sounds like they are being bleached by the bulb being too close.
but more details and pics would go a long way in making a proper diagnosis

Blatant, dont mean to sound stupid but wot is TDS?

mybeans420, the soil plants r shorter, i thought the same thing at first (to close to lights) but the hydro plant has its full colour so its gotta b some kind of nutrient lock up in the soil but wot? not many deficiencies start at the top of the plant, i was thinkin maybe sulphur, it must b one of the micro nutes, theres deffinately a reduced yield. If i can figure out how to post the pics il get em on today, i took some last night. peace

 

[LeeroyJackson]

sry for posting an OG link but look for Sulphur deficiency picture half way down.
Thats about all that came to mind when you said yellowing tops.

Thanx leeroy, seems it could well b the sulphur it must b getting locked up for some reason, il try adding epsom salts next grow . peace

hey D, try watering to the point of run off and check your ph, btw. whats the ph of the water your useing ? anywho the more stable the ph the less" lockout " you'll have.... jus a thought....

 

[LeeroyJackson]

Bro, now that you post a pic, it just looks like normal N being eaten up as you enter late flowering, its normal. I wouldnt worry that much about it. How much longer you going to flower for, didnt you say your in late budding?

Hey B.C, thanks for the input i try and keep my p.h at around 6 to 6.5. I use filtered water through a brita type water filter and this gets rid of alot of the shit from tap water and it brings the p.h down but not all filters bring it down to 6 i can b 7 sometimes, but its better than usin acid to bring the p.h down .peace

They hav around a week to 2 weeks left some r infront of others iv started flushin them already . The yellowing started from the top of the plant about 2 weeks after being induced, theyve had plenty of nutes too so i dont think it could b N. Thanks for the input. peace

 

[LeeroyJackson]

**They also seem to hav a considerably rreduced yield?**

Soil will yeild less than hydro most of the time anyway, with exception to monsters in dirt like BOGs trees or TomHills outdoor venture.

Theres 3 other descriptions that fit the middle or top part of the plant for yellowing and dying/browning that i found, you probably have looked at them but ill post them anyway in case.

Zinc, Molybdenum and Iron, all of these occur in the middle to top of plant.

Maybe it helps, not sure.
Best of luck,
Leeroy

Thanks leeroy but i was refering to previous soil grows which to look at wud match the buds on my hydro plant, though this is my first hydro grow. peace

 

[LeeroyJackson]

Have you been using alot of nutes by any chance? or off ph?
