Ppm question

I've got a standard ppm meter off Amazon. Transplanted clones into ff happy frog soil almost 2 weeks ago now. I dont understand much about ppm, but as far as I understand it reads the amount of minerals and nutes in your water? I gave the plants a nutrient watering when first transplanted and the run off was super high in the 2800 range. I've now given them I believe 2 or 3 ph waterings and the run off is still in the 2500 range. Is this normal for a nutrient enriched soil? I figured if I just do straight water for another week or 2 it should bring the ppm down, does that sound right?

Also, would it be more beneficial to water them more than I am so the run off is more substantial to flush out the nutrients? I'm basically giving each plant a half gallon of water every 4 or 5 days or whenever the soil is getting dryer, and the run off is maybe a 1/6th of what I'm giving them. Its not a whole lot coming off of it cuz I haven't wanted to drown the roots.

Runoff ppm in soil is not accurate. You have no idea what you're flushing out of the soil and concentrating.

What do the plants look like? If they're healthy don't worry about runoff ppm. If they're showing signs of overfeeding then feed them less.

If you keep flushing to try and get the runoff ppm in soil to match some number you think it should be all you're going to do is deplete the soil. Use you're ppm meter to check the strength of your nutrients when you feed not for checking the runoff in soil.

For sure. Tbh they look like they're slightly developing deficiencies. Small light brown dots on a few leaves. Besides that they're healthy as could be. Ill start them on a every other water feeding.

Yea like homeboy said soil ppm is always high as hell due to the nutrients in the soil that haven't been taking up by the plant yet. All your doing is just flushing out nutes your plant is gonna end up needing down the line. Hope this helps, stay lifted

So first few pics are some of the spots. I dont know if im supposed to remove the leafs that they cut the tips off as a clone when it gets to this stage or leave them. The last 2 pics are to get any opinions of when I should flip to flower. I'm at 20" from the canopy and only have another 5" i can raise the light. When do you guys think i should switch into flowering? I know its a small tent i just don't have the room for bigger.

Happy frog is basically all nitrogen so you probably have some toxicity going on brotha. And your plants are gonna stretch 2-3 times the height they are now so you might wanna switch to flower within the next week or so

I've noticed a few of the leafs also having slightly burnt tips nothing major though. How would I fix too much nitrogen?

And if your using calmag dont give as much till you bounce back
I've only given 2 nute feedings in the 2 weeks of them being transplanted. I have the fox farm trio and was told by someone else not to use cal mag cuz it isn't organic and happy frog is organic? Idk man, didn't realize this shit would be so confusing lol.

I feel you bro it is hahaha. Those 2 nute feedings may have had (N) tho plus the (N) in happy frog, which is why your getting burns and what not. Just make sure when you use nutes in your water your ratio starts with a 0. 0-4-4 or something like that

And your supposed to go half on the recommend amount of nutes you use too. Idk how i forgot about that lol

Yeah I did a 1/3 my first feeding cuz they were transplanted for only a day or 2 and then I did a half of the big bloom which is 0 - .5 - .7 the other 2 i have are tiger bloom and grow big which have 2 - 8 - 4 and 6 - 4 - 4 so maybe I need a different nutrient thats 0 N to do in the mean time thats more than the big bloom.

Yea its just the amount of (N) its getting bro. Easy fix

Did you start your seedling in HF and transplant to Hf as well??
