deficiency

Hey I was just wondering if anyone is able to tell me what the issue with my plant is? Cal mag deficiency or something else? Thanks

Fellow growers, what's happening! I swear every run I run into some kind of new problem that I was unaware of! This round I have a maui wauii that is very strange. Its yellow striped which looks like an excess of calcium, but the weird part is it's all bubbly/pimplely, the whole plant. It's...

Help me out guys, I am pretty sure this is nute burn as I started feeding these seedlings with liquid nutes early as they are in coir and perlite... Haven't fed them for four days now, they were watered daily but the leaves are still browning at the tips, any thoughts or advice?

OK so I'm in my 7th week of flower and my chemdawg isn't doing as well as my LSD strain. It's either withing or drooping and has dark green leaves. And one leaf has these tiny spots.

Last run I noticed some strange paterns on some fan leaves that at first glance thought it was powdery mildew but its not powdery at all and does not rub off. Is this some type of fungi or strange deficiency? See pictures

Hi all, So these plants are under CLW SS550s on a 24 hour lights on cycle. There were 2 nights in a row were the power cut and the lights were off for the the better part of 12 hours. Once I had corrected this I noticed they had started to flower so I changed from 18/6 to 24 to try and...

So I just diagnosed a calcium deficiency in one of my plants. Upon doing a little research, many places said to flush soil and then add missing nutes. I'm more than happy to simply follow directions with something I don't fully understand. But my question is why flush with deficiency? I...

Greetings coco growers! I've been having problems with early stage plants in coco for the past 5-6 grows so finally I decided to post as I have been running out of ideas. Plans on the pictures are in week 3, about 18 days since I places them in rootriot plugs. They are slow and some of them...

So a few days ago I noticed some lower leaves turning brown on the ends and edges, then they started to twist and curl upwards. After I noticed it we had an ice storm. I couldn’t keep my night temps warm enough. For about 3-4 days it got as low as 55-60F in there. Probably even lower below the...
