Possible Nitrogen Deficiency?
greenhousegrowgirlstarted grow question 3 years ago
Is this a nitrogen deficiency? I had a yellowing leaf or two at the bottom of the plant which have since dropped off, but rest of the plant is looking patchy now. I have just switched from fish mix to bio grow.

If u can measure the soil ph u can do a perfect job of this. Ur soil ph levels should be between 5.8 and 6.2.
5.8 early days and 6.2 towards the end. But obviously the pH of the water u add means nothing if the media is not the right levels for the plant to be able to take the nutrients it needs. U can find charts for the different types of media ie. Soil, coco and probably more, with a pH chart for the different nutrients. If ur like me and like to know the chemicals then that's the best piece of information u can have.

Hi BeautifulCraft, thanks for your response. I have been using the PH number in the diary to capture the PH of the soil, not the water. Maybe that is wrong. My soil PH is 7 (which I hear is normal), but I always get the water to PH 6.5 after I have added the nutrients so it shouldn't be that.

Doesn't look like a nitrogen problem, I seen in your diary your water pH is 7 and. That's a bit high I would lower it to 6.5

Yellow on leavesDay 13 leaves started to look yellow / dull on tips hasn't seemed to improve 2 days later, it is the auto soil premix I'm guessing the roots are getting close the soil and nutes kicking in or does this look like another issue?

Leaf IssuesHey all, my almost 5 week old Moby dick auto flower is starting to show some issues in the first week of flower. She got a dose of Veggie nutes 5 days ago, and a little bit of Bloom yesterday trying to fix it. Temps have been high and humidity low, would that cause this?

2 autos with crispy feeling sad looking leaves, how can I help them? (more info in diary pl & crit)2 of my autos have been growing leaves that feel crispy and look deformed. I have been watering when the top 5 cm of the soil dries, but I fear maybe I fed them too much nutrients. The temp has also been on the high side (30C 80F). What could be wrong and what can I do for them?

Foxtailing Yellow Leaves White Trichomes - WHAT HAVEW I DONE?!Hi! It's my first grow and I thought I was Doing alright. After I've bought a tent, seems like things got worse. My flower is an auto in week 13.4 (supposed to take 9-10weeks) and I'm flushing since about 10 days. Still the trichomes are pretty clear. What should I do?

Buon giorno weed doctors, did anyone have similar uniform chlorosis at the top or maybe knows what's up? What could be the reason and the solution? ThIs this some sort of immobile nutrient deficiency or excess? Could this be caused by heat and light stress? She is 80cm tall and almost touches the lights in the tent. I'm usually suffering from Calmag and Nitrogen issues and haven't yet experienced yellowing from the top. Thanks

Should I do full flush til runoff is 300ppm?So, it is obviously a deficiency, which probably caused by a lockout. Will the full flush solve it?
Yesterday I fed her a full dose of flowering nutes. Including K. It didn't change much. Lower fan leaves continue to go yellow.
Today 3L water, pH:6.2,
runoff:0.6l, ppm:1450, Ph6.0

Advise to flush or feed in VegDoes this is look like a nute burn, deficiency, or ph problem? The two plants that are growing a tad taller have had yellowing tips some curling downward. Don’t want to overreact and cause it to worsen, they’re looking healthy otherwise. Any advise whether to flush or feed?
