2 quick questions

Hey guys, happy thursday. I have two questions regarding Mg, Ca and Sulfur. I've hears that Ca antogonizes with Sulfur so I was thinking:
a) Would it make a difference if I foliar feed epsom salts (Mg and Sul.) instead of mixing it with calmag and base nute(and keep feeding calmag and base through the roots)?
b) I've heard that Calcium is not important during flowering, so during flowering I'm considering replacing Calmag with epsom salts and feed through the roots?

Reason I ask this is because I've had Mg def. in the past and CalMag is usually only 1%Mg. Thanks for your time and God Bless.

Making things too complicated.....Things are much simpler than you assume... I wouldn't get caught up in presuming possible chemical issues and then find prevention is worse...
Personally, I plant a seed in my chosen medium and it gets all it needs for 3 weeks with nothing but water....By then, it has started telling you what it needs....after all it is just a weed.

Honestly, I get what you're saying. Like I said, I've lost plants because of overfeeding, I messed up plants and I underfed plants. And I get that each plant will react different. I have an auto in BioBizz Light Mix. I've been feeding 1/4 of First Feed from Plant!T
(pH 6.2 - 6.5) which is nutes for cuttings and babies. On the 11th day, I noticed rust spots. I searched around and it 100% looks like Ca def. Last plant had Mg def, now I get this. I really don't want to make things complicated but I've been having issues.

I personally stay away from spraying anything on my plants....those water droplets can cause burns on the leaves and make the plant more prone to overwatering. They also say plants dont use much Nitrogen in flower but you still have to give it because it does use some.

Thanks for the reply but I don't think that the droplets act as a magnifying glass. There is rain in nature. Have you noticed spots or anything when you spray with lights on?

Watering is pretty tough with a small plant in a big pot. I realize it is recommended for auto's, but it doesnt make it any easier.
At this point you would be safe fully watering the pot, and waiting for it to totally dry out. I dont foliar feed so i am not familiar with any of the problems or benefits that come with it

I've grown 2 autos indoors and 3 outdoors and I've always wanted to start with smaller containers and transplant but I never took the risk. To be honest, a transplant does not sound shocking to the plant at all for me but since I still consider myself a noob, I'm not risking it.

I grow in small pots, starting in solo cups and moving to 2-3 ltr pots at 1 week.... which I find very easy to control watering. I slide my moisture meter into the root ball and water when necessary. Slowly water until meter moves to desired level.... I find a 2-3ltr pot takes about 750ml water/feed...I never water till runoff only till meter indicates needs fullfilled.

Interesting. You're talking about autos or both autos and photos?

I don't like spraying my plants either, especially in flower, but I have foliar fed Epsom salts. It has the advantage of being immediately available to the plant without having to go through the roots so you don't run the risk of locking anything out, and the results are a bit faster. You can also spray on days where you wouldn't want to add any water to the root zone. So, say you notice a mag def after watering. You can spray immediately without waiting for the medium to dry out. It's not like those 2 or 3 days are likely to kill the plant, but you have the opportunity to watch it a bit closer and see if it stops progressing. If it keeps going despite the foliar feeding you know something else is going on.

As far as the droplets acting as magnifying glasses, yes that can happen. Spraying close to lights off is an option, but it really depends on your setup whether or not it'll actually cause any damage. One option is to spray one leaf with water, and then see if there's any damage.

These autos were transplanted from starter containers to their final 3 gallon pots. I don't think they look stunted at all. :confused:

Give it a shot next time. People act like autos are super sensitive versions of photos. I treat both autos and photos the same, they both get the appropriate quality care they need. Good luck.

Maybe I'm mistaken? This is Gorilla Glue auto from Barneys at 15 days old, grown in Biobizz Lightmix.
That burning in the margins is pH fluctuations.

Are u pHing ur nutes and with what? As long as it’s 5.5-8-0 it’s fine for soil. Messing about with it can cause more harm than good.
