New grower Strange yellow leaf problem

[stinkyattic]

They may not need a flush; check your soil runoff pH first! And check the COLOR of the runoff... it should be fairly clear, if a bit dirt-y. If that makes sense. If it's yellowish, keep flushing, lol. And if the pots have drip trays built in, take them off before flushing, as they will block the drainage!
Oh 12/12... only if you want to flower right away. You might want to hold off and keep them on 24/0 until you are certain that they are perfectly healthy. It is harder to fix shit in flower.
You are making me blush! I gotta run, back Monday.

stinkyattic Reviewed by stinkyattic on 04-25-2008. New grower Strange yellow leaf problem So i just recantly started growing and had some problems from the start but things seem to be shapping up. Still some strange yellowing is appearing on the top leafs that are under two florecent lights i have. The yellowing begins were the stem meets the leaf and up towards the tips its a more normal green color. The yellow is a verry bright yellow and like i said the yellow fades more towards the top of the leaf and turns back in to a better looking green. Is this a nutriant def or mabey a ph Rating: 5

Sounds like a plan! I Will check all my PH levels for soil, the water i use, and my house tap water PH. And if theres any thing out of wack i will let you know! Thanks again HERO!!!!!!!!

Hey stink! hows it goin i got thoughs PH levels for you and they were a little high. The water i use is my house tap water wich has an alright ph level of 7.0. My run off was also at 7.0. but the water that I have been using is in an old orang jucie bottle. I rinsed it out and then filled it with water and let it sit for 24 hours but after testing the ph wich was 8.0,BAD BAD BAD, I quickly changed bottles and am using the water at 7.0 should i try to lower it by flushing my plants? Should i keep using my tap water? What do you think? Let me know o great one!!!! lol :thumbsup:

Tap water is fine, I haven't read the other posts but just looked at your picture.

It looks like you're suffering from lockout issues caused from too much nutes which in turn probably the ph in your medium. Some of your leaves look burned while others look like iron deficiency issues. I doubt you're having it both ways especially using tap water and your nutes should have micronutes in them like iron so this shouldn't be an issue.

I would suggest flushing with tap water 3x the pot size (ie: 3 gallon pot = flush with 9 gallons of water). then immediatley after flushing give them a light feeding (1/4 or 1/8 strength) nutes to help replenish what you've washed away.

And yes, keep using tap water. It contains calcium and magnesium. Something you have to supplement if you water with distilled or RO water. So unless your city water is bad/has high ppm then I would recommend that you just keep using it.

P.S.S. The numbers on my nut's (maxigrow)10-5-14.

The MaxiGrow you got is fine for vegging, but you'll need a nute for flowering, too. One with a lower nitrogen level. (MaxiBloom)
While at the Hydro shop, and since you'll have your wallet out anyway...might want to ask 'em about micronutes as well.

I'm surprised he didn't try and sell you a 3 part nute system. These 'systems' usually include a bottle of vegging (grow) formula, one bottle with the micronutes, and a bottle for flowering stage (bloom).
