One out of nine has yellow leaves

[marso5050]

Well, as the title says, my plants are all looking quite healthy, except for one.
The picture does really show, but this baby is very yellow compared to her sisters.
Top leaves have only 3, 4 or 5 branches, other plants have 7.

soil is cocos
temp is around 30c (86f) - still summer here
water is Ph balanced, soil Ph unknown
been watering day on day off. Now everyday
light is 16/8, will start 12/12 next week after repotting
using Wortel Bcuzz and Hesi TNT

over-watering will cause yellow leaves, as well as other reasons ... your pot looks too small, which would explain the frequent watering ... normally, you should be watering only every 3-4
days ... it needs to drain very well, and dry out between waterings ... if it is done exactly as the others, then it may just be a weak plant, it happens in nature ... :smokin:

looks like a potassium def

whats ferts are you using?

complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph

[marso5050]

I did the runoff and the yellow water gave me a yellow answer (correct Ph).
I've reduced again watering (once every 2-3 days) and I hope the girls won't complain.
I will transplant to larger pots as soon as I buy them, this is my 1st grow and I still lack some material.
The ferts come from Europe. Wortel from Bcuzz is a root stimulator (no indications about the composition) and TNT complex from Hesi is a NPK fertilizer (6+2+4 means, I think, 6% Nitrogen, 2% Phosphorus and 4% Potassium)

I think I'll just take this plant away. Too bad we can't know its if it's a female.
Anyway, thanks for the advices.
