Ok So my plants have been growing for a few weeks and doing great. I just bumped up the nutes about 3 days ago. I went to check on my plants when the lights turned on today and i found most plants have yellowing spots on the leaves. Can someone please help me identify the problem. I use water that has a PH of 6.5 - 7 and I'm using Fox farm nutes and Fox farms Ocean forest soil. :-(

lower your ph of the water to 5.8-6.
Ocean Forest has enough nutes inside that you dont need additional nutes until 12/12

Flush it good and let it rest for a week and check back.


+rep for not using Miracle Grow

Thanks for the rep. Did you ever hear of using apple cider vinegar for lowering ph?

WTF... 5.8... Don't do that!!!

Soil works optimally at 6.5 pH.

FF Tiger Bloom is notoriously hot and acidic. If you are using that then back off on it for sure.
Your problem is most definitely Cal-Mag related. A good top dressing of Dolomite lime will help buffer an acidic soil media and provide a variety of micro-nutrients like calcium and magnesium. Humboldt Nutrients Sea Cal and Sea Mag, or Organicare Calplex and Huvega are my organic liquid nutrient suggestions.

Get that pH to 6.5 and make those elements available! A flush of 1 gallon water to 1 gallon soil at 6.5 to 6.6 pH should do the trick. Test your run-off to see the difference between what is going in and what is coming out to get an idea of where you're at pH wise. If the run-off is more acidic than the flush solution then you probably have a salt build-up and that's your primary problem.

I could be wrong but I think he was talkin about the ph of the water goin into the soil, not the ph of the soil. I'm not a soil grower so I'm not sure if it makes a diff, but.....just my 2 cents

Thanks for the response. I'm not using the FF Tiger Bloom yet only Grow Big and Big Bloom. I tested the runoff last time i watered with nutes and looked like 7 but I wasn't sure if the nutes skewed the results.

Anyone else have any input or idea what it could be?? I guess I'm gonna do a flush and wait and see. Ist a bummer plants were coming along so nice.

The damage is permanant. The plants, however will outgrow it if tended properly. If it hasn't been getting worse continue watering as normal(without nutes) You have enough in there already. Everyone forgets, it's a weed, not a potatoe. Don't ever put in the maximum amount of nutes. The weed will do great on a fraction of that total(1/6). If they continue to die you'll have to wash the roots and transplant. But with the pics I don't see that happening. Your plants will survive. TOO MUCH lime can harm them also. Before you do anything to radically change the ph of the soil do a ph test first.

Thanks for the reply. You think its nute burn? I only used a cap full of Grow big and a cap full of big bloom in 1 gallon of water.

They are just growing really fast. This happens sometimes.

If you had some silica supplement around that'd help with the rigidity.

Just imagine the cells splitting apart at slightly different paces depending on where on the leaf they are. This creates a kind of warping and twisting when the leaf is young. A good way to supplement during this period is with plenty of structure building nutrients like iron, zinc, silicon, sulfur, magnesium and of course NPK. So basically... everything. Not calcium so much though, I mean, a balance is needed, but not too much Ca right now.

I vote against the Cal-Mag Plus. Too much calcium, locks you into a ratio with your magnesium, and it contains EDTA which I'm debating whether or not is a good chelating ingredient.
My first suggestion is Organicare Huvega. It is LOADED with micro nutrients in the levels you need them, is organic, and should be perfect in your system. They suggest going with Humega (a humic chelator) but I think Liquid Karma would be a fine addition to your system in the place of that stank ass stuff.
My other suggestion would be something like Su-Po-Mag, or a Langbeinite supplement (google it).

You really could just ride this out, or get the Cal-Mag. Just make sure you feed your girls right now. Plants grow exponentially, imagine how small they were, and how little energy they were absorbing. Now think about how much more energy they are getting, and how fast they are going to grow given the bigger they get, the faster the grow!

They are on 12/12 right?

Lots of pics to give an idea what they are looking like.
