pH Problem?

All 3 of my plants are showing this damage in varying degrees of severity. Is this a pH problem like I think it is?

This pic is from my last grow but my current ones are showing the early signs of this. Only the oldest leaves on 2 have gotten as bad as this so I want to stop it ASAP.

Oh yea my pH was 5 last night, after flushing this afternoon its closer to 5.5-6. I've only fed once with grow and vigor nutes at the strength listed on the bottle.

Bump... no one has any ideas? I really rather not lose these plants considering these aren't bag seed like my last grow.

Need more info... what medium are you using? If it's soil then you've probably got lockout so get your ph up to 6.5-6.8

heya mate..i think you overdid it a bit..although its just a guestimate i make....looking at the hight of the plant she's just a baby...and you should Not feed the first couple of week(s)
it also depends on what you use for soil....is it nutrient rich or not?

nhow....and if you start feeding the plant...you should take in consideration that you should not start off with a compleet dosage...you have to build that up...
so i think you are toasting your small one

You can see how stunted and damaged the Easy Ryder is, it was started the same time as the smaller DDR and its half the size.

Looks burned from the nutes imo too. FFOF should be good with just water pretty much the whole life for an AF. Maybe a little something mid to late flower but it's pretty hot outta the bag, again imo.

if it started before you fed them then its probably is a deficiency or overwatering. how warm are the tops of the leaves? it coud be heat damage from the bulbs

I think I got it back under control, they all are showing new growth, even the little Easy Ryder for the first time in a long time. Hopefully it was just the pH and as long as I stay on top of it they won't have this happen again.

Looks like a pH problem to me. You need to flush and check pH with run off. The only way you will know forsure.

I having the same problem with my AK47 x Diesel

:dueling: I've been fighting soil pH problems for my last three grows . Hope I get it under controll this time

flush your soil with plain water ph @ 6.8 when flushing fox farm soil has nutts in them water should of been good for a few weeks of vegg till leaves got alittle light on color then you could of hit it with mild nutrients and also its time you up the size of them pots
i know they are full of roots you also have root bound but first flush then wait few days them transplant.
note when you grow in soil you want to put soil in a foam cup water with ph'd water and get a reading on run off that way you know what your working with i also do check tds reading and if needed to up my ph i use powder lime i had this happen month ago i dont check the happy frog soil and had same problems same company makes the soil fox farm
the ph was 4.3-4.7 and TDS was around 3000 PPM lots of nutts for now on i will be testing before i plant cant trust lables

I say flush it no matter what. Get your PH right and hit it with a max of 1/2 strength nutes and work your way up. FFOF has a good 2 weeks or nutes in it already.
