Three autos 2 moby dick and one strawberry cheese preflowering since may23 ….Well from week two of these autos I introduced fox farm trio into my soil with half the recommended dose ..two feedings later I noticed burnt tips so I stopped feeding them noticed a little leaf problem shrugged it off a week went by and got worse so I figured deficiency so I fed them but only a quarter dose of the feed this time then clean water next now this is how they look idk nuet lock something ..any botanist around!?

What soil? What's your watering schedule like? What pH? What kind of light? At first glance, they look hungry/thirsty, but bud development looks good.

I shoulda added today was water day for them ..Soil is 5year old horse manure does great for veggies ..I don’t have a set schedule for watering when the pot is light weight I water … one gallon of water per each two gallon pot the light is a Mars hydro fce3000 on about 75 percent soil ph is is around 6.6

I'm not a botanist, but i'd feed them. I havent used fox farm trio, so I don't know what to expect from that. Also, i've only grown photos, no autos. I use GH flora. If mine looked like that at this stage in flower, I would give them an 80% strength dose of flower sched nutrients. I also add 3ml/gal CalMag which gives a little extra N from the Calcium Nitrate.

So you’re saying just give em a fat dose of nutes ?

Check your run off PH and PpM. Judging by the pale green colour and purple veins in the leafs your ph is off. I would not hit them with a "fat dose" until confirming your run of PPM is OK.
Sadly the only ph tester I have is a junker I know when I water them the run off is a brownish color

What PH does it read?

In the absence of a PH reading.
I would flush the pot thoroughly once she drying. And then feed with a moderate dose of nutrients immediately after washing the substrate out and see what happens

Yes, I would feed them. If you're worried about burn, then reduce to 50% strength.

I don't see any Calcium in those nutes. Are you feeding with tap water? Do you know the ppm on the water and what it has in it?
I know I deff have some hard water tears coffe pots up haha

6.6 little heavy towards 6.7.Thanks man if it doesn’t improve after this watering of a third of nutrients recommended I might just flush and start over but I’m skeptical …got any readers you suggest ?

I use these cheap ones. You have to calibrate the pH meter semi frequently. I know my tap water is reliably 6.4. When the meter starts to drift, I recalibrate it.


For calibration:

I get the ph part and what not but the ppm is what gets me sounds stupid but say I test my water boom 6.5 35 ppm ….I add nutrients test that water then test my run off to see if ppm is higher coming out then going in im gonna order one but I want to understand it first !

PPM is parts per million of Total Dissolved Solids (TDS) in solution. It is derived from a measurement of the electrical conductivity (EC) of the solution, which comes from dissolved electrolytes (salts). The synthetic nutrients like FF, GH, etc are salts. Also, tap and well water have some things already dissolved in them. Maybe bad things like NaCl too, so it's useful to know what's in the water, especially if it's hard water (has high ppm).

35ppm is low for tap water. If your water is hard like you said, it will be over 200ppm. Mine comes off the tap at 120ppm. When you water, test the runoff. If the runoff is in the 1000ppm range or higher, then your soil already has a lot in it. You shouldn't need to add more to it, but I don't think that's your case based on what you've said already. When I mix my feed at this stage in flower, I shoot for between 900-1000ppm, but that's knowing that my soil is not overloaded already.

When you mix your feed, first make the mix. Then, adjust pH. Then, apply.

Wow man this was very informative I appreciate it so is my soil on a straight water test reads over 1000 it doesn’t need nutes any higher flush and restart any lower feed ? And I’m sorry to be a pita but say after mix ph reads 6.8 say how would I lower it I did order exact one you have !

That one I posted has one set of calibration mix powders for the pH meter. Be sure to use three separate clean glass cups and distilled water when you calibrate. Follow the included instructions!

Lower the pH using anything acidic. The nute companies sell pH down and pH up solutions, but I just use vinegar, lime juice, lemon juice for down and baking soda for up. You only need a little bit to make the pH change, so go little-by-little until you get used to the amounts.

If ppm reads 1000 and your pH is good, but the plants are not feeding right, then I would flush till the runoff ppm comes down and finish it off by applying a fresh mix of nutes. I don't think that's what you're going to see though. I think you're going to need to adjust the pH and feed.
