p4tm_CHEFstarted grow question 6 years ago
Hiyo. Plz notice the 10/30 pics. Should be about 4 more weeks to harvest. I know she is going to start going off as we get closer but this is a couple weeks early for my liking. Any ideas? I water/feed with the basic fox farm trio. With 4 weeks left is it an issue? Thx.

That looks like calcium deficiency. That happened to me on my first diary due to my soft tap water. Your pH is okay so it's not a lockout due wrong pH. There's always the chance it's lockout due to excess nutes but your feed looks fine, unless you are feeding too often? Before rushing to buy any calcium / magnesium additive, I would meassure the EC/PPM of your water, it should be around 0.4 to 0.5 EC (200 to 250 PPM), less than that and there's a very good chance it's calcium deficiency, since it's happening on the newer leaves.

Heyo chef so ill agree with athos on this looking like a calcium issue, its on leaves that are being exposed to the lights which is classic calcium...however a couple other things stood out to me, if youre using water from the tap not bottled ro water theres usually a good amount of calcium available. I also used the fox farm trio and it worked great, however i eventually added a flower booster of theirs similar to what you show, the low N and very high PK and while 2 of my plants further in flowering did well, 1 did not and displayed these similar calcium looking deficiencies even though i was using a calmag supplement. So i later found out that excessive amounts of potassium display almost identical symptoms. Unfortunatey into flowering usually the affected leaves wont recover. But you seem to have many healthy leaves still. I hope you can get to the root of the problem, and definitely check the ec/ppm if you're able like athos mentioned.
Keep up the battle and happy flowering. ✌️

WHY?? Still looks like Calcium Deficiency?? HELP!!!Can Someone Please tell me what is going on here? I have a detailed diary if you have any thoughts on why it still looks like a Calcium Deficiency. Plant looks healthy except this. First time for coco (bagged & prebuffered), grow dots, and wick bases so I am at a loss.

Calcium Deficiency???So this is a Calcium Deficiency right? Noticing on top leaves. Not bad yet but want to stop it before it starts as this grow has been my best so far. I have been using CalMag every water but I did lower the dose for a few days as I was told I was using too much for flower.

One plant (the one on the right) is going yellow, with brown mottling on the leaves. Both plants have been treated exactly the same.
I’m giving the plant some calmag and extra nutrition after flushing it (which had no effect). Any ideas to save this plant? Worried…

Look At This Pigmentation!Lower fan leaf vs upper fan leaf in the canopy. The difference in pigmentation is wild! It almost looks like its bleeding.

Is that not enough calcium?How can I recognise that it is only a calcium deficide? The plant is also the largest and the only one with such deficiencies. Could the plant also be lacking manganese or magnesium and what can I use to compensate for this? Are pests or diseases excluded?

Week 2: One of the plants still doesn't look good + other beginner questions :)Second week and one of the plants has weird spots + leaves curled.
Not sure what to do. Do I overwater? Is it some kind of disease or deficiency? No idea.
Also, when should I start feeding the plants?
And how much water do I need at this point? 😥

Brown Spots on LeavesI’m noticing some light brown spots on my leaves. After researching it seems that it was either 1) Manganese deficiency 2) calcium deficiency or 3) overwatering. I don’t think I’m overwatering. It could be the nutrients but would like input!

Why do my plants only have that light greenish yellowish look at the top and why is one of my plants also having those sick leaves at the bottom?2 of my 3 plants are a bit yellow-ish at the top since about a week. Plant 1 also had a couple of sick leaves at the bottom that I did remove. Those leaves had brown/dark spots, felt dry like paper, had very purple stems and did smell more like hay. More info in my report.
