Right guys my girl is 28 days into 12/12 under 600w hps in biobizz all mix soil. being currently fed 2ml bio grow and 5 ml bio bloom per 2 litre give 5 ml of grow last feed to help with fast yellowing problem. I from what I can find it seems to magnesium but I gave a high dose of epsom salts over a week ago so I'm stumped.the problem is only on top leaves no lower leaves showing this sign also got yellow tips on my sugar leaves, and a brown spot on a sugar leaf and again this is only happening to top part of the plant no lower bud sites are affected so here's some pictures getting really worried now received_811183238924849.jpeg.jpg received_811183005591539.jpeg.jpg received_811182905591549.jpeg.jpg received_811182835591556.jpeg.jpg received_811182802258226.jpeg.jpg received_811182752258231.jpeg.jpg

I am curious what your PH is running at feed time, as it seems to be a cal-mag deficiency or lockout. Are you ph'ing your water?

Hello my Friend,

It's kind of hard to see with your lights on. I had a similar problem, mine was caused by overwatering/high humidity. When did you feed her last? Remember your affected leafs won't recover. Sounds like you're going in the right direction in regards to your feeding regiment but it's going to be hard to tell if you're on the right track as vegetative growth has stopped. I was also thinking it might be a Cal-Mag issue, however you usually notice this only on juvenile plants on lower leafs. My guess is a humidity in conjunction with overwatering, try and keep the air rather dry during flower as this increases resin production. Hopefully someone with more experience can give you more insight.

Good luck,

What strain you running? I am having some similar issues with some Barney's Blue Cheese right now. Having a hard time dialing in her needs.

Your water online? Test what is physically coming out of your pipes. A number on a screen isn't going to be completely accurate.

My tap water comes out 140ppm at 7.3 - 8.1ph. I add cal-mag until I get to a base line of 200 in veg and 250 in flower. I then add my nutes, wait a few hours and then ph down to 5.8 ( hydro) It usually goes back up a point or two after a couple of days, I add a bit more ph down and that is all for that res for the week.
If you are going to get serious about growing, you really need a good ph and ppm meter.
