I changed to 12/12 operation a week ago. I also switched to a HPS bulb and increased from 450 to 600 watt power. Additionally I changed nutrients to Dyna Go Bloom 3-12-6. Since the change my plants have gotten lighter, almost yellowish. The temperature has increased about 5 degrees after bulb change and watt increase. Now in high 70 range and sometimes low 80's.
* Is the yellowing due to nutrient shock or deficiency?
* Will the higher temperature cause any problems?
* Has my soil depleted and now other nutrients need to be added?
* What if I go back to 450 watts on my lighting?
Thanks for all your help!
Pretty definitive answers for no pics and very little info bro. Yellow certainly doesn’t automatically mean they’re hungry. It also doesn’t necessarily mean deficiency. he said hes using a 3-12-6 nutrient so N definitely isn’t “gone”*Yes
*No
*Probably
*Don't need to
If they're yellow, they're hungry. Since you switched to a bloom formula your nitrogen is probably gone. I'm not a soil grower though so not sure what to tell you to do exactly.
Everything looks good to meThe girls may not be as yellowing as I first thought. They don't look like they did a couple weeks ago. Much darker green then. I was using Miracid for 5 weeks then switched to Dyna Foliage Pro for one watering then to Dyna Bloom. I am using 1 gallon pots about 1 inch from top in Fox Farm Ocean Forest. I know the pot would do better at 2 gallon but I was not looking for gigantic results. I attached an image. All ideas are welcome. Thanks to all of you!View attachment 777472
I know some people feed grow nutes the first few weeks of flower. I understand the thinking but I have never seen a plant hungry for N unless they are not being fed at all. I switch to bloom nutes the day of flip. Bloom usually has plenty of N to run thru veg and bloom if you wanted. Plenty of people do.Looks great man! I wouldn’t switch to a flowering nutrient right at the flip to 12. As member mw7945 pointed out, the stretch at week 1-3 in flower can be nutrient and nitrogen demanding. I would suggest switching to Bloom nutes end of week 3 into 4. Thats what I do. The photo period is the main driver for the flowering mode anyway. All we do is feed it along.
