Hi there! If your plant tends to be lime green or pale all over, even though the leaves appear healthy without stripes or spots, then it's a Nitrogen deficiency. If your leaves are clawed and have a deep dark green, then it's a Nitrogen abuse/burn. If your issue only concerns the highest leaves, then it could be a light-burn. If your issue only concerns the new growth, then it could be an Iron deficiency. From what I see in your last pictures, this looks more like a deficiency. In every scenario, wrong pH can be involved. I'd recommend to re-calibrate your tools and double check your pH. Hope this helps, keep us up-to-date so we can help you in parameters adjustments, and happy growing!

First of all, get an EC/PPM meter, it will go a long way in taking out the guess work.
Second, yellowing tips are not a sign of nutrient deficiency, period. It's always a sign of nutrient overdose

Possible calcium def. or other issue affecting leaves and budsIs this a calcium issue, and if so why is it spreading to this one bud in particular?
There are four photos of the effected bud, as well as a few shots of unaffected buds to compare. Also have spotted leaves that look like ca issue but not sure why its spread to the one bud.

Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on AutoWeek 8 (flower) top leaf tips are reddish and the leaves are more yellow than green. Does this mean that my plants need more nutrition?
I am using Jacks 3 2 1 for two autos and using it at 65% strength (650PPM / 1.2EC). Should I goto 100% at 990PPM / 1.9EC or 50% to 550PPM/1EC

I noticed recently that a few of my leaves have these white spots on them with a little damage on them as well. Would this be linked to my slug problem? Or is it something completely different? I have been applying neem oil every few days but it doesn't seem to get rid of pests.
