this is my first time growing in coco. I'm using coco choir and perlite mix from Plagron and 4-4-4 and 3-9-4 organic dry amendments from dr. earth. I'm using 300w led lights. The temps in the tent are 77 degrees and humidity is around 45% i'm watering with ph 6,0. the plant is showing yellow leaf tips but it doesnt seem like nutrient burn they are just yellow. what seems to be the problem with the plant and how do I fix it?

How far is the light from the tops of the plants? What is the manufacturer recommendation?

it's about 25cm from the light (10inches) but so are all the other plants and they are fine the yellow leaf tips started showing once i I transplanted her to a bigger container. I used plagron coco and perlite mix with dr. earth 4-4-4 and 3-9-4 dry amendments, bat guano and worm castings. could the nutrients be the problem? maybe i I added to much bat guano?

10 inches is probably too close. How big are the pots, and how much 4-4-4, 3-9-4, and bat guano did you use? What's the NPK of the guano?

the pots are 20L smartpots. I used 4 tbs of 4-4-4 and 3-9-4 per gallon in the ratio 70:30 and about 5 tbs of worm mix and about 5 tbs of bat guano. the guano NPK is 4-16-3

So 20 tbsp TOTAL of 4-4-4 and 3-9-4 ya? Probably too much phosphorus from the guano. Looks like you transplanted and probably just switched to 12/12? They don't need that much phosphorus that early into flower.

It sounds like you're treating the coco like soil. Coco needs to be watered frequently and kept wet. You don't want to let it dry out. Coco does best when watered with a nutrient solution and treated more like hydro than soil. The clawing of the leaves is significant and a sign of overfeeding. If you're going to grow using coco you should follow tried and true methods for success. As for now all you can do is keep them watered and hope for the best. Unfortunately those plants will probably get worse. Good luck.

^^^ This

The dark green and clawing is nitrogen toxicity. Coco doesn't hold water like soil. So you have to water daily. With dry nutrients in the Coco you release nutrient each time you water which should be daily.

You need to choose one of the many well balanced Hydro nutrients or move to soil
Good luck

Can i do anything else to help the plant besides watering more frequently. and would i be able to grow in soil using plagron lightmix with the same organic dry amendments from dr. earth?
