Magnesium issue?

[Strawberryman86]

Can’t figure this one out, haven’t changed anything from a successful prior harvest... using a 2 part duel fuel from green planet.
Temp 77 on 65 off
Hm 58. 52
600 hps 24 inch above canopy...
I duno

How is your nitrogen ? looks a bit yellow but that could be the HPS.
BTW Welcome to RIU.
Are your in Soil, If so what kind ? have you checked the Ph of the Soil ? if so what is it ? Remember don't over water, let her dry out till the containers fairly light, then water.
Good Luck Keep us posted on your progress. Again Welcome To RIU

Pro mix hp soil ph is 5.3 I usually let em dry out pretty good prior.
Nitrogen is good.

pH is off. You want your pH much higher at 6.5. That will fix them.

PH should be at 6.5 man unless your doing hydro then its supposed to be at 5.8

Probably locked out nutes

I wonder what caused it to be different same water same nuiets same temp same strain. Everything I haven’t changed a thing.. what do you suggest I do if you don’t mind me asking lol.

whats the issue ? i cant anything with the yellow lol

 

[Strawberryman86]

purple in the stalk limp leaves they seem to be growing slowly..

 

[Renfro]

raise your pH to 6.5, that is all

People spend their whole life studying single nutrient deficiencies and still never understand what a plant is saying which is why soil analysis is used to actually pinpoint weak links.

Ph is such a farce, ignore it unless your growing in water and inert media.

Your plants look hard to revive - you got fans pointing at them or something like way too many nutrients idk but your pretty much killing them and without good health a 600w 90 odd lumens is pushing the far too hard.

If it were oh id expect to see ph damage not limp lame paleness sorry, maybe stop ph'ing andpost a water report we can tell you simply your good there.

Completing ten more grows will help if all else fails as youll soon spot whats off

That why I always say, you gotta add Dolomite lime to pro mix as i have never had a bag that was above pH 5.6. I always add 1/8 a cup for every gallon of medium, or 3/4 cup per cf! Then you can water with whatever and the medium will buffer the pH to where it needs to be!
