What deficiency is this? *pictures*

[Shafto]

First time grower, I'm seeing this on my leaves on an AK47 10 days into bud.

In sunshine mix #4, feeding every 3rd watering with the recommended dose of technaflora bloom solution PHed to 6.0 as it says to do.

I know I bleached out the plant a bit by putting the 1000W too close to it, because if you find leaves and shoots that have been shaded by other leaves they are more green. I have now moved it further away, but I think this brown stuff is caused by some deficiency I have, since it's on the lower and older growth.

The chlorosis looks like your standard Nitrogen moving out of older leaves....


the dark spots along the veins are typically caused from the too many metals in your food causing toxicity and necrosis....

But that opinion is based on little but a guess based on pics....


and I dont even know where on the plant they were ...

and many yada yada's


And that could mean you are overfeeding or...


the ph is a bit low......

Sunshine mix #4 is hot. If you just trasplanted then flush the shit out of it. Your run off will be a puke yellow and the ppms will be off the charts.

It's "hot" ?

I thought it was soilless and nothing in it other than what you add.

Runoff was quite yellow though, but it has been watered with lots of runoff twice. I just fed it again today. Run off was 6.0PH and much more clear.

I'm all DWC now, only started with a few in this sunshine mix #4 because I heard it was easiest for a beginner. DWC is much easier and I'm glad I've switched, still have to ride this one and a couple more girls out though.

symptoms on lower/older growth normally means a mobile nute is laking. since as you stated you just put them into flowering 10days ago, your plants should be in the stretching phase. streaching plants use a lot of N, Mg, and P, so much so that if giving the right environment, plants will outgrow there roots ability to uptake nutes. this will cause a mild deficiency which will normally clear itself up. with that being said, your leaves look way past mild I would start by adding a lil more N, Mg, and P. if you dont have bud sites yet, you can foliar feed to give them a quick shot of nutes to help until the roots can catch up with the plants needs. if you do foliar feed, remember to do so away from your lights so water doesnt spray your bulbs and cause a rupture. also let them dry before putting them back under the light so you dont cause burns on the plant. remember to make your foliar feed LIGHT. you can always feed them more later, but you cant take it back after the fact
good luck hope this helps

Thanks for the help.

The AK in the one on the right, bleached out from light too close, and this brown stuff.

It seems really healthy other than that, growing like.. well, a weed.

Lots of hairy bud sites already, so no foliar feed. The deep green is starting to return now that I have the light raised up to a proper level.
