4. What type of hydro system are you using?hempy
5. What brand/type of nutrients are you using?gh flora series
6. What is the Ph of your nutrient solution?5.7-5.8
7. What is the PPM/EC of your tap water?well water/dont know
8. What is the PPM/EC of your nutrient solution?dont have a meter
9. What is the temperature of your nutrient solution?60's
10. Does your PPM/EC show a rise or fall when you do your daily PPM check?no meter
11. Does your pH show a rise or fall when you do your daily check?its hempy silly
12. Do you foliar feed or spray your plants with anything?tried misting with 1/8th tsp epsolm salt per liter yesterday. helped a little, now prgressing some more.

18. How much experience do you have growing?inside-about a year


so im guessing this is a mag problem.

ive moved the plant away from the light thinking it could be that, but nope. sprayed with an epsolm salt spray yesterday, but seem to be getting worse.

was giving it a 2-2-1 mix of grow micro and bloom.

just gave it a 3-2-1 mix today, plus 1/8th tsp of epsolm salt.

anybody have any ideas on how to stop this? what do you suggest for a dosage of epsolm salts each watering.?

this plant is from greenhouse seeds. i know a lot of his plants love magnesium for some reason.

i know i will need to add some for every watering, but dont know how much i guess.

IS---Yes the raised edges, darker green and lighter green colors does look like a Mg deficiency.

I used to add 1 teaspoon per gallon when using epsom salts to fix problems, but I'd suggest lowering the grow back down to 2,2,1 or maybe even 2,1,1 with the epson salts the first time so not to burn them. They look plenty high on the Nitrogen at the moment with the dark green spots, and mainly needing the Mg to even the color back out.

Might even just try a dose of the epson salts alone to make sure they color starts to even out and the edges go down without burning them.

Happy Growing

Hey ILLEGAL-SEED

Might not have anything to do with it but whens the last time you re calibrated your PH meter? I see some signs of PH stress...

All the best,

good eye.WeeD22MaN

my meter is trash. my new one should be here tommarow.

ph was a bit off on all plants. the new growth for the past 3 days show that my ph is fine now.

my kush was the worse. but thats all taking care of now, and wont be a problem again.

thanks alleycat i have a gallon of 1 1/2-1-.5 that i will add 1 tsp epsolm salts too. hopefully it will fix her up.

i guess i was using a really low dose at 1/8th tsp.

My opinion: it looks exactly like mg def...It almost has to be ph related. mg is one of those finicky nutrients that is absorbed at higher ph's. 5.8 and above in hydro... since you are using the 3 part and one of the parts is the micros, it has to be getting locked out by the ph. If you keep trying to correct the deficiency by adding more of a nutrient and it turns out ph is the culprit, you will burn the shit out of them once the ph is corrected. I'm sure you already know all of this but I wanted to try and explain it so a noob with a similar problem gets my

Proper PH?

i dont think its ph just because the other 3 strains were getting the same mix mostly all the time. mixed together in the same bucket and everything.

could be wrong though, but not one hint of this on the other plants.

cant wait to step on my damn meter and smash it to pieces.

Swapmeet

Man... you posted that at the same time as me. I would flush the plants with phed water only, then add a fresh dose of the 3 part after a couple days of pure water. (I am assuming you need to water every 2 days)

If that was true, then wouldn't all of your plants have mg def too?

thats what im saying. i dont think ph has anything to do with it. the ph was the same for all the plants. this is the only plant showing it. i think its just a magnesium lover.

ive watched a few greenhouse seeds videos, and he mentions a lot of his plants need extra magnesium...dont know why...must be in the genetics he uses.

going to try and wait it out. hopefully tommarrow the new ph meter will be here, and i can be sure the ph is fine. then ill just flush it, give it half strength nutes with 1 tsp epsolm salts. hopefully will solve everything. hopefully.

Swapmeet

Sounds like a solid plan to me.
