About the 3rd, 5th and 6th picture. What's that? I always assumed it was P deficiency but I got P def on another plant and it doesn't look like that. I've had the same stuff on multiple plants. Also about the 4th picture, bottom leaves drying and white-ish between veins

Nutrient deficiency or surplus?
Hi Guys will post a pic shortly. Have to update the grow as we are actually heading into week 6. One of the white widows is a fair bit smaller than the other. And is showing some form of difficiency or nutrient burn. I think it may be due to to little phosphorus. Opinions?

Recently noticed some of the leaves on my GDP plant are yellowish and have some odd dark spots, hoping someone could tell me what it looks like to them. Should I stop feeding her? only a couple weeks until flush... thanks

I found a few holes that looked like a Caterpillar was eating my plant but I haven't found any pests. Perhaps a fungus??? Anyone know what this is due to? I sprayed bubba with neem oil just in case...haven't found anything since.

Sick plant, could be temp, nutes, too much water?
Leaf tips looking burnt and wilting in flower ... keeps getting worse no matter what. pH 6.8. Raised light. Too many nutes? but a couple days with water only and it's still getting worse. The other plant seems fine. The buds seem OK. Maybe heat? Soil is 69F. Overwater?

Calcium Deficiency? pH problem?
Brown spots on some newer growth now on both plants. Canna Terra Flores brings the pH of water down too much even at a half dose. I didn’t think I’d need to adjust pH much in soil. Any suggestions at this point? Thinking to just feed plain water to bring the pH up at the roots

Their appears to be little brow spots/specs scattered on the fan leaves, I feel like I’ve seen it before but completely forgot what it was so if anyone knows if it’s a deficiency of any kind it would be appreciated. I ruled out nute burn because only one out of four has it.

Some spots appeared. Only on mid leaves. Yellow spots. I've counted four. I'm feeding her with a mix of tap water and bottled water (using pH down to adjust at 6.0) and atami Terra leaves.
