So at day 55 I'm noticing that some of my leaf tips are looking a bit burnt and some rust colored spots are showing up on the leaves. I read that this might a deficiency of cal or mag or a ph issue. Just wondering if any one could help my diagnose this issue and try to fix it.

What could this be? Deficiency, or pests?
White Crack in coco, currently late veg / pre-flower stage. Canna nutes being fed at EC 1.7 / pH 6.0 with runoff EC 1.3 / pH at 6.2. Noticed this on a single leaf this morning. Only change in last few days is that I am now filtering my water before mixing in nutes. Any thoughts?

Root rot or pH imbalance?
This blueberry muffin (f) plant was doing well until last week when it started deteriorating. Its grown on a mix of cocopeat, vermicompost, perlite mix and fed on compost tea and cal-mag mix. I might put it down eventually but I checked the pH and it was 5!

Nute issues... Any ideas?
Nute issues.. any ideas? It looks like and iron deficiency, Cal-mag has massively helped throughout its life but still get it on the older leaves. Plant looks healthy otherwise. Maybe PH too hight or too low... I can almost work it out but for a quick look from diff eyes

Cause for mottling leaves?
I think this mottled leaf coloration may be due to slightly high pH or just stress from the repotting over the last couple of weeks.. Most leaves are fine but a few look like this. Any thoughts?
