Hi, I think your lamp is too close... otherwise, water with pH-adjusted water. ...and reduce the nitrogen, it could be a calcium deficiency... and magnesium too. Also, what stage are the plants in? A full photo wouldn't hurt... Thanks, see you later!

What nutrient deficiency is this?What nutrient deficiency is this? Or is it nutrient burn? I'm watering with 5.5 PH using half strength Nutes, Root booster & Calmag. I don't think it relates to spiders mites since I can't see any with my 30x magnifier. Thank you so much in advance.

Day 14. Since day 12 a brown spot has appeared on one of the leaves of the first node, spreading little by little. Because of the symptoms, I think it's septoria, so I've sprayed neem oil to see how it works for her. Someone knows what can it be?

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.

I added a couple pics of what looks like rust spots on the leaves of only the tall plant in 7 gallon. I’ve given these two plants the exact same feeding so not sure what is causing it.

The brown spot problem is still the same. I reduced the fertilizers to 1/2 dose according to the week after 1 week of just bottled water. The pH of the solution is generally 6.3-6.5. Apparently, the central cola is thicker, but I find it hard to notice the difference.
