Plants have some kind of problem. Looks urgent.

Hi My plantshave gotten very sick. I have been feeding them AN super tea with some silica blast and a drop of super thrive. ph~6 and the ppm between 400-600. I went on vaca and dropped the nutes to around 250 and when I got back they looked a little puny so i re-did their regular regimen and they have been getting worse for a couple days. I started a flush with clearex yesterday cause they are about a month old and I figured it was time to anyway. They are looking worse. What do I need to do?

Feed. Its some kind of deficiency.The new growth looks fine, plant is eating lower leaves for nutes

you got some magnesium deficiency, your starving your plants. what kind of nutes are you using? i'd spray them with cal mag and add some to your reservoir.

Ok it was probably because i underfed them for four days. I ws terrified of overpowering them while I went on vacation and burning them to death. any idea on what the deficiency is?

ok I'll start them a new solution and add cal-mag. thanks.

you need epsom salt or cal mag and give them a tsb/gal. are you using micronutrients?

yes some maybe not enough though

you need to get a fertiliser like AN grow micro bloom since ur already doing AN. micro is the most important part. You need to monitor your nutrient solutions PH and ppms daily; add more nutes or dilute as needed. creating a stable environment for your plants is important.

That looks ph related, growth is green but leafs are shrugging. If ph isn't the problem look at the color of the roots and make sure water is correct temp.

Also they might look like shit from you flushing them. Let them grow and keep your nutrient regime simple
