started grow question 5y ago
Any thoughts on these brown spots? They have popped up on a few leaves on the same plant (Amnesia).

Not sure, looks like damage from the fan or just a damaged leaf. Don't think it's a nutrient issue.

Which deseas did my plant have?
One of the plants shows an illness. What can it be? I had previously sprayed the plants with water.

Lemon Ice 2.0 - Browning leaves Weird Growth
Anyone got an idea what may have caused the weird looking lemon ice to grow like that? I'm guessing a fungal infection or mold, which is weird tho cuz all of them got the same exact feed, time in the plugs etc. Basically its odd because it only affected one (thank fuck), ideas?

Rusty Leaves
3 upper fan leaves have "rusty" brown spots on the upper side. Hard to spot, hard to capture on camera. I also have slight "clawing" on many of the upper leaves. Mg/Ca lockout because of nitrogen toxicity possible? Doesn´t seem to be fungi, as there are no spores to rub off.

Been wilting every 2-3 days and then recovers after watering. Brown spots appeared in the last 24 hours. Pictures of leaves off and on the plant in latest week's pictures. Water ph'd very high (7.5+) and I have lowered to 6.5 for this watering with 1/4 strength nutes and vinegar.

Unknown rust on 7th flowering week
This started as what I thought was a cal/mag deficiency, bought some, gave it for a week at a good dose and 6.3ph, and this intensified and switched from just lower leaves to the upper and a few sugar leaves on one plant. Any ideas? May calmag takes awhile? Or wrong diagnosis?

Late Flowering Stage Deficiency or Nutrient Burn
I'm not sure if this is nutrient burn or some sort of deficiency. Burnt tips were from possible previous nutrient burn, but now I'm seeing Brown spots and some discoloration. Please check my week to see full details.

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.

Flush or what to do ?
Advice please. I watered yesterday but the stains on the leaves are getting worse. Now I don't know if it is deficiency of cal n mag due to nutritient lock out which might be due to ph being off as I have 5 reders and all of them show a different thing. 🤦♀️...or it is it rust?

Thoughts, should I be concerned?
One of my plants is developing twisted and spotted leaves. Is it just to much nutrients or something more?

Possible manganese deficiency?
I fixed some previous issues and have not been feeding my plants. They are in peat and worm castings and pearlite. About 6.6ph soil, watering with 6.5-6.6 water. I am going to water with nutrients again to see if that helps just want to hear another opinion.

Is this turning purple from temp change
So it looks like what I thought was a brown spot (under the grow light), appears to be purple when I pulled it out to get a better look and stake it down. I did switch the light to something cooler, could this be from temp dropping. Not worried yet, just curious. Thanks
