RedCherryShrimpstarted grow question 3 years ago
Hi guys any clue what this could be? Got this problem since 3 weeks and i thought at first that it was a calcium / magnesium deficency... so i added BioBizz CalMag. Unfortunaly nothing changed. pH is 6.2 - OK?
The upper Leaves curl down.
The plant is a x.C.K Brazil from KC Brains

It could be a few things:
Clawed new growth could be EC, pH or toxicity related.
The yellowing leaves suggestive of calcium issues, either too much or too little. This can be a result of pH being out of line, too much calmag in your feeds (are you using tap water or RO water? Don't forget tap already has calmag and RO has nothing in it at all). If calcium is in too high levels it can block other nutrients so can cause a series of issues quite quickly.
Might be worth a flush - as you are in coco you can flush and try to restore your medium in just 2 or maybe 3 waterings so youbshould be able to pull it back to a baseline quickly and start it up again.

Clawing can be nitrogen excess- and nitrogen excess can lock out calcium or magnesium - can’t remember which one but keep that in mind as a possibility

Leaves have developed "claws" at the tips that bend downwardsMy leaves have developed "claws" at the tips that bend downwards.
I suspect there is too much nitrogen because I probably used too much root juice. (Approx 8ml, scale was inaccurate)
Now my question to the professionals: what can I do to fix the problem?

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?

Am I overthinking things?Any idea what’s going on with these ladies? Or am I just over thinking. They just seem a little unhappy. Watered 750mil yesterday morning the last time before that was 500mil Saturday night. Could they be a little overwatered?

Too much nitrogen and underwatering?Hey guys, can anyone tell me what they want (or have too much off?)
I think the big one has a bit too much nitrogen is my guess?
I also transplanted them today and yesterday so they had a bit less water as usual the past days. Could that be it as well?

What do you think is wrong with my plant. It's starting to grow nicely but was really slow at first. Tips curling down. One leaf crispy.What do you think is wrong with my plant? In promix moisture soil. Fed nutes twice. 2mL of micro, grow, and bloom. Last feeding I added 5mL of calmag. Soil is 100% inert at least from my research. Watering once soil is dry (every 5-7 days) One leaf is crispy. Tips curling down.
