Hi there need some help/info. my 2 autos are 1 month and 2 weeks old and there turning yellow with whiteish rush vains on leaves.

Big 1 on the left is weddin cheesecake and small on on the right is weddin glue from fast buds.
Feeding 400ppm ph 5.8
Had a lil nute burn 3 weeks ago flush them and since shown these signs.

Haven't been feeding calmag dw it's on it way..

Using canna coco feeding line with canna coco professional as my medium with 30 percent perlite,also few hand full of cley pebbles in the bottom of the fabric pot for drainage.

I think these girls are asking for calmag and some more food but before I start pumping them back up I wanted to see what you all had to say.

You shouldn’t need Cal Mag with the Canna line of nutrients as it already has it accounted for. Also no need for extra perlite or grow stones in the bottom with canna professional. You need to up your feed. Your plants are starving & need nitrogen badly. At this stage in their life they should be around 800ppm DAILY for auto’s

What would you say 1/2 ration of n to flower nutes

No, just up A&B. Keep rhizo, cannazym, & boost the same. You should be able to drop the dose of rhizo pretty soon. When you do up A&B a bit more. You always want to feed equal amounts of A&B

Your coco looks extremely dry. You should be feeding daily to significant runoff which you obviously are not. They could probably use a stronger feed as well but you should start with proper care of the coco. Start by upping to 600ppm with proper feeding.

That burn was most likely because you have used too big pot, which led to disability of proper treatment and resulted in high medium EC. Supposing you have flushed with plain water…? That sudden fluctuation has definitely huge influence on the roots. Those plants could be grown in 1gal and with that small one you would be still on the edge. You want bounded roots and coco always saturated with nutrients, thats the time when it starts to work like hydro. In that stage you can not overwater, but in your case I bet myself you easily can, thats the reason why you are so shy with watering. Maybe I am wrong, but since your pot does not allow right treatment of the medium, you will always have some issues.
