Yellow is NOT good

[mactight]

I have some Diesel that is in the third week of flowering,I use ocean forest ,with tiger bloom and big bloom.I use at every watering.2tsp of tiger per gallon and 1 tbls of big bloom per gallon.I have them under a 400 HPS.Temp is a steady 80 with the lights on and the upper 60's when the lights are off.So my question is,my plants fan leaves are starting to lightly turning yellow,outterside in.Only on the upper leaves on the plant.Am I giving it to much nutes?Does any one elese use what I uae?and have much do you use and in every watering?Thanks everyone.

Are you monitoring the ph of your soil and feeding water? You have to use ph up with the FF line. It sounds like a deficiency but it could be brought on by a ph problem.

Please try to post pics.

Well here are acouple pics for you all to take a look at,Also I do watch my PH levels and they are around 6.8.I just do a PH test in the soil after I water.

[mactight]

Any one got any ideas?

[jbuzz123]

that happened to one of my plants i had a lil pinch in the stalk or a bend and it cause just the edges of leaves just like that to yellow! take a look at the stalk and make sure its healthy! good luck mac ph causes alot of isues too! go with bombs advice!

I do watch my PH levels and they are around 6.8Lower your ph to 6 until she looks better then go with 6.4. 6.8 is too high and you probably have some sort of nute lockout. Don't flush her just water her as normal with a ph of 6, flushing while your babies are stressed isn't good imo and can lead to root rot. Shouldn't be long before she looks better then resume with a ph of 6.4. Good luck:D.

Lower your PH as Bomb. has told ya, I would backoff on the nutes as well, every watering is too much, Do you know the PPM of the nute solution your using?

[bombbudpuffa]

Use lemon juice for ph down. Water it with plain ph balanced water until your problem resides then resume normal feeding.

You need a PH meter or at least the PH test drops, nobody can answer how much to add.

Also PPM meter is handy to measure how strong your nute solution is, without knowing nobody can say how much is too much.

Ohh yea PPM stands for parts per million and measures the amount of disolved solids.

[bombbudpuffa]

I usually start with 1 mil of lemon juice then work my way to the right ph. 6.8 is too high.

What kind of ph tester you using? I have had no luck testing ph, my cheap soilmaster tester from lowes never moves from 8. Can anyone recommend an accurate and affordable tester?

Can anyone recommend an accurate and affordable tester?I just have a cheap tester you stuck it into the soil and the needle bounces around then slowly comes to where I THINK its at.So any suggestions on a better one or if the one I am useing is fine?

[turfsire]

hey man it more than likely a ph or lack of nutes..u can get a cheap ph tester kit online or if ur not livin in america u could get it in any headshop..hemp store
;)

You should be only using nutes EVERY OTHER WATERING..

thats what it say on the feeding schedule.

and your plants will lose some of its fan leaves.
it natural. like trees in autumn.

I use Vinegar for PH down.

This is true but not starting at the top and going down. He has some sort of lockout.

Got this pic from OG's nute deficeincies: They say it's Phosphorous deficiency:>)

Which agrees with my veiw that your're under feeding them a little;>)

If you check my gallery all of them are grown with FF!>)

[bombbudpuffa]

I do watch my PH levels and they are around 6.8If his ph has been 6.8 and he has problems I can almost guarantee it's ph related not under feeding. If he continues to add nute while there is a nute lockout if or when the ph problem is fixed he'll have nute burn from over feeding. Get the ph lower and see if that helps BEFORE adding any other nutes as GD said. If this doesn't help, which i'm positive it will, you should then think about nutes:D. Good luck.

Use lemon juice for ph down. Water it with plain ph balanced water until your problem resides then resume normal feeding.I havent had alot of time to get on here,but I had to water them today.I did add some lemon juice.I didnt know how much to add,so I just gave it 5 drops of lemon to a gallon of R.O. water.I did a test in the soil and it was still 6.8 After this is under control,do you recomend useing TIGER and BIG Bloom ever other watering?

[bombbudpuffa]

do you recomend useing TIGER and BIG Bloom ever other watering?I wouldn't really feel comfortable telling you how much to feed your girls. I don't know how big they are, whats in your soil and every plant is different. I will definitely tell you they need some bloom nutes once everything is in order:D.

I will definitely tell you they need some bloom nutes once everything is in order:D.I will figure out the nutes for the ladys.BUT, did I put enough lemon juice in with a gallon of water?or do I need to add more?How much lemon juice do you put into a gallon of water to bring the ph down from 6.8 to 6?

[bombbudpuffa]

You need a ph tester. Theres no way I can answer this because it will be different everytime:(.

You should NOT use aquarium PH chemicals. It's been said that they contain different ingredients that can cause root problems.

Also, here is a list of things you MUST consider when thinking in terms of pH which directly effects your PPM levels:

1. Electro-Conductivity (EC) or Conductivity Factor (cF) can be expressed as either milliSiemens (mS), cF, or parts per million (PPM) 1 mS = 10cF = 700ppm.

2. The pH and electro-conductivity values specified here are given as a broad range. It should be noted that specific plant requirements will vary according to regional climatic conditions, and from season to season within that region.

3. As a general rule, plants will have a higher nutrient requirement during cooler months (temps), and a lower requirement in the hottest months (temps). Therefore, a stronger nutrient solution should be maintained during winter, With a weaker solution during summer when plants take up and transpire more water than nutrients.

4. KNOW YOUR CROP. Plant EC or cF may vary according to the stage of growth. For example, cucumber prefer 20cF when establishing, and 25cF after the first harvest. Between 5 and 7 weeks after first harvest, the optimum cF is 17.

5. The nutrient solution should be discarded at regular intervals. Should there be a requirement to flush the growing bed, the system should be flushed with fresh nutrients (run-to-waste) rather than water to avoid starving or stressing plant.

You need a ph tester. Theres no way I can answer this because it will be different everytime:(.I do have a PH tester.Thats how I know its at 6.8:D When I add the 5 dropps of lemon to a gallon of RO water.I tested it and it was still at 6.8.I understand that I will have to add more lemon juice next time to help bring the PH level down to about 6.So,10 drops to a gallon,might be closer or any ideas?I am trying to bring the PH down to 6.:hairpull:

[bombbudpuffa]

Go by mil not drops. You'll be dropping all afternoon:D.

[mactight]

Go by mil not drops. You'll be dropping all afternoon:D.I am confussed:eek: Is that 1 millaliter per gallon or??????

[stamb]

I think this is from temperature differences or overwatering. Try to keep your night temperature higher. Look at this gude:http://www.icmag.com/ic/showthread.php?t=11688
see Miscellaneous Sick Plant Troubles at the end of the post and the overwatering paragraph. good luck with your beutiful ladyes ;)

Night temps should be 10-15 deg lower or it will cause yellowing.

[bombbudpuffa]

[md.apothecary]

hmmm... that's interesting. Never heard/thought of that before. That's a pretty significant drop in temp. And in many cases can be unrealistic. I mean if the temps in my house are 85 degree in the grow area, and our house normally sits at 78, that's only a 7 degree drop in the best of the best optimal conditions. :holysheep:

I read this somewhere but have not found it, it was talking about how to limit stretch in flower at nite.
It said to keep the nite temps close to the day temps but not to go over the day temps or it could cause yellowing.

Im sure 7 deg drop is fine.
