Mg foliar spray? Or how to Save them

GreyArea51started grow question 3 years ago

Should I do a foliar spray with magnesium (epsom salt)? The run off ppm is around 700, my last 2 feedings were just pH 6,5 water because they got burning tips. I think they were a little overfees and then the mag ded started to show.

Spray under the leaves just before lights out. That's the best time for an epsom salt spraying.

Yeah dude, or a few mins before lights come on. With spraying you will see improvement in days,

Thanks, should i spray right after lights turn on?

Hashyanswered grow question 3 years ago

You might be best off doing that, make sure your on fine mist with the spray as you don't want big drops of water staying on the leaves.

Newer growth is lighter in color and thicker than the other leaves. She was under my humidifier so maybe drinking too much? Dry organic amendments so no additives in water. Several other grows in same feed schedule and no issues

Hey Guys, two or my plants seem to have a few yellow tips and some brown spots on the leaves. The problem is minor but I think it might be lacking Calcium? I think it needs some Cal Mag added to the next watering. Any advice would be appreciated. See pics. Thanks

Over the last week, I have noticed quite a lot of yellowing of leaves, along with them drying out and getting brittle. Now that I am checking the PH of the nutrients, and adjusting to 6.0, I have no idea what's going on. Any insight as to what the issue may be, is appreciated.

Is it normal for new growth 10 days into flowering to be lightening in colour? I am new and noticing that it is fairly lighter than previous veg growth before as my nutrient needs and feed has changed. Just want to be safe! Thx 😄

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Hello guys! Overall the plant looks light green/yellowish and pretty small, with short internodes and bottom leaves with burnt and curled up tips. I give water every 3/4 days and commonly suggested fertilzers quantities. How can I let her recover and get bigger? Thanks :)

So, my other plants have surpassed this OG, unfortunately, a week younger, too. I took pictures of the PH test Do you think that was the problem? (I personal so I don't water for the first 3 weeks, lol, otherwise the above happens.)
