Deficiency discoloration?
GrowBrosInc
started grow question 5y ago
I noticed some light de-coloration on the tips of one of the tops. Is it just because its new growth or do I have a deficiency? Thanks for the feed back.

Looks like the start of a cal mag deficiency or a ph problem makes sure those 2 are in line and you should be fine.

Not normal, maybe a magnesium deficit

That’s not normal, could be magnesium deficiency but I can’t be sure. How much Mg are you giving to the plant? It should be between 50 and 80 ppm

Hi! im experiencing yellowing and falling leaves in all the strains i planted 5 weeks ago. Only lower leaves. Thought it could be nitrogen deficency but already fed them with N nutrient and still slowly yellowing from bottom to top. All plants are in early flowering stage.

Nute burn other symptoms. Is this a case of overwatering?
Hey peeps, One of my plants (start of week 5) Started with burnt tips due to nute burn which I've taken steps to halt. Lower leaves started yellowing and drooping, but now a few newer leaves started showing yellowing as well. Is this overwatering + nute burn or is there more?

Small yellow stains
Hello colleagues! Would you kindly help me and tell what these yellow stains may be caused by? I think I could set the ph-level too low, so it may be a deficiency of some nutrients, but the plant seems developing normally.

what is the problem?
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:)?

I think it's calmag and lack of nitrogen but any ideas. I've been busy in the garden so have taken my eye off the ball. She looks in great health with praying full leaves but her colour is off. Any ideas would be taken with gratitude.

bottom leaves yellow
Helloo So today I've noticed that the bottom leaves are yellow. I don't really think it is a problem since I think the reason is that they don't get enough light because are covered by the bigger leaves on top. But it's better to ask since I'm a newbie. What do you think?

Calmag Deficiency? Yellow Spots
Last res change I saw some yellow/brown spots on the fan leaves up where the main cola was getting too close to the light. Is this a calmag deficiency or light too close? I moved the light up to the top of my tent with zip ties and got back several needed inches. See pics.
