I'd give it a balanced fertilizer. FFOF can't feed them alone forever. You could throw more FFOF in that pot too. That pot looks about half full. That does look like Mg deficiency to me.have these ww autos growing in ffof. They’re about 30 days old and I’ve made plenty of rookie mistakes. This looks like a magnesium deficiency to me but… I give ph water and for the last week I’ve added cal-mag to the water. My ph going in today was 6.8 and 5.6 out. The ppm going in was 535 and 2650 out. All 4 plants are showing similar signs. Can anyone help get me back on track? Thanks, pin
theyre under 400watt mh lamp 18/6
How far away is the lamp?
It’s about 24” I just revamped the space and also turned the ballast up to the full 600watts..
What were you running it at? 300w? she definitely craves more.
I did...I didn’t know any better at the time.i was worried that I was gonna shock the shit outta them with the 150w hps to 600w mh switch so I thought I would ramp it up slowly. I also had the light too high (like 30”) for a good part of that time. The light is now at its full 600w and my newly installed fan is keeping temps at about 75f. I did have heat issues before the fan which also contributed to my dimming the light...
That’s pretty similar, interesting... my girls are white widow af from seed king. I don’t understand how a plant under a 1000w mh can be light deficient. I kinda feel like I have crappy genetics but I’m probably just looking for excuses.
You worry to much. Ive sprouted seeds under 1000w HPS. Granted they were 5-6 feet away from the bulb but i did it with no problems. Get a lux meter and learn your bulbs and hot spots. A 150w HPS 6'' away is way more light than a 1000w 5 feet away. Its all about finding that sweet spot.
Oh I’m sure I worry too much. I have the light about 20” now. These girls are for sure underdeveloped for the age (about 30 days) so I’m pouring my heart out to get them what they need.i had better luck when I was a teenager growing under fluorescent.. lol.. now I’m spending the coin to do it right and having issues all down the line.You worry to much.

How to Use a Lux Meter to Increase Cannabis Yields - RQS Blog
Among pH testers, loupes, and refractometers, lux meters are a useful tool cannabis growers can harness to ensure optimal plant productivity and health.www.royalqueenseeds.com
Sounds like you bought a shit load of lights you didnt need......
Not really. The 150w hps was free. Then I got a sweet deal on the Vivosun 600w with digital ballast. I’ll most likely switch to led after a grow or 2
