Miscellaneous. Potential mold, pH, nute issues

[militia420]

1) I'm medical. I've got some pretty heavy issues that have mess up my memory. I'd appreciate help Id'ing and remedying these issues as it's my first grow in 6 years due to health probs.

2) Here's the images:

No feedback on the gray dead spots or any thing guys? I hate asking for help but I've learned, due to my health issues, that it's stupid not to ask for help when you need it. I don't want to lose these plants as I'm broke and it's the middle of the growing season here..

You should give more details about the grow - lights, age, medium, nutrients, feeding regimen etc.

From the pics, it looks like more than one issue - 1st pic has almost all visible leaf tips burned, albeit just slightly (i.e. overfeeding), the one in the second pic looks underfed, judging by that sad pale green, the 3rd & 4th look like Ca deficiency, while the last one is N def. I'm not saying I'm 100% on all, but they are clearly different issues. And when that happens, the culprit is usually pH. Do you monitor your pH going in and/or out? Do you have runoff? Did you ever flush them?

One more thing (and I'm definitely not an expert here, just voicing my concern) - those plants look ready to be transplanted out of those solo cups. I transplanted mine when they were less then 1/4 that size, but they already had roots all over the medium and coming out of the drain holes. And if your plants are root bound, that leads to a lot of problems. Also, they look kinda lanky, where are you growing them? Because they don't seem to be getting enough light.

My best guess going forward - transplant into new pots, preferably with fresh medium, if you can be gentle with the roots while washing down the old one. Don't overwater them, let the roots expand into the new medium, start feeding them light and monitor your pH going in (and out, if you're growing in soil).

Good luck!
