what is the problem?

RoyColtstarted grow question 2 years ago

The colors of the leaves make me think. I don't give a knock during these weeks of bloom time. Do you think this is a lack of calmag? or this is normal:)?

Ph for everything soil and water is a low 6. I feel like it's underwatered but I'm not good with reading plants

Yellowing leaves help please (newbie)Hi guys, had a calcium/ magnesium deficiency last week which I have treated with calmag this week However I’m concerned the plant is yellowing more. Is this still related to the same issue ? I understand the brown spots won’t be reversed but should the leaves still be yellowing?

Does the paleness concern you?Plant #1 seems a bit more on the pale green/yellowing side of the spectrum. Especially compared to plant #2. I have been feeding this week on a gradually increasing schedule. Not enough characters to go into it here.

Hi 8th week of flower. Bottom leaves have turned yellow and died and yellowing is rapidly moving upwards. I think it's nitrogen deficiency so I've added more Biobizz Grow. Would be good to get an expert opinion! Thanks

Nutrient lockout?Having a problem with bottom leaves turning yellow and dying. Starts off with brown on edges and tip, then leaf yellows and dries up. Potassium deficiency? PH problem? I flushed plants yesterday with 6.5 ph water and sledgehammer flush from fox farm. Pictures on week 10. Thanks!
