Brown and straight with spots is potassium deficiency signs. Also check pH in substrate to ensure it is not a lock out front that. If that is is range then I would increase potassium level.

Leaves turn brown all of a sudden
What could these brown parts mean? They show up randomly, also on lower leaves, so couldn’t be the light being too close? Thanks!

Do these look healthy? Thoughts? I'm new to hydro/growing
I have autos growing in a dwc system being fed half the regular amount of hydroguard, calmag, and grow/bloom. 1 plant is a week younger. The dark green plant looks like its leaves are clawing and has big brown spots on the leaves. The other has some brown dots and little yellow.

When should I put the pellet in the 5 gal pot??
I am currently growing a tangie'matic with "a pot for pot" grow kit. At first the seed germinates in a pellet. Then it says "put pellet in 5 gal soil mix after 10 days or when the third set of leaves matches the second." I did it after 10 days and this happened.

Brown Rusty Dots
What are these brown dots on my plants? They are only on one of the plants, they have gotten a spray with Dr. Zymes Eliminator and had no effect, also did a mL of Cal Mag in its last water with no effect and getting worse. I’m not sure what this is and I can’t get it to go away!

Emerging Issues - Week 9
At the beginning of the week, I noticed the tips of the leaves drying out. Now, one out of the four plants has completely yellow leaves. Could it be due to the increased Biobizz Bloom dosage? For more information, please check my journal. Regards.

Do I have to worry?
Only on one leaf of one plant. Is this some fungus or virus? It looks a bit like coffee rust, but I couldn't find anything else like it. How should I proceed? Thanks in advance!

Brown spots on the Gold Leaf?
Brown spots with light yellowing. Possibly calcium deficiency? This is only happening on the Gold Leaf. Neither of the GDPs are showing these signs. This has happened over the last 2-3 days.

Browning leaves? Did a soil slurry and dropped the water from 6.8 to 6.2. Does that mean it’s locking out? How should I go about fixing this? In peat pearlite and worm castings. Added about 6 cups of lime to the 20 gallons of soil thought that should have helped the ph?
