Which deficiencie?

[STILLSMOKIN]

0.4 is my Tap Water alone. I Add 0.3 to my Tap Water and 0.6 Base Nutes. Total EC 1.3 now

That's how she looks today

Looks good to me. She is just a fast grower and needed calmag. I had one that done it all through grow, then at the end leaves darkened when she stopped stretch.

What is light distance and spectrum though? She is staying short.

1.2 is too high IMO for sure. Looks like she is getting locked out. Flush it, and start over with quarter nutes at that age. Those recommendations are for photoperiod plants, not autos. Autos can survive on 450 at that age. Start her at like .5 max and see what happens. I bet she will like that.

To flush, just run 2 times he volume of your pot of phd water through the plant, then start over mixing a new batch of nutes.

It would also be interesting to find out what the EC of your ground water is, plus if you have a bunch of salt build up in your coco. Did you flush the coco before using? What brand is it?

Hey, I grow an Auto bevore under Coco and that EC and now Toxicity.

My Run off was today 0.8 EC i feed with 1.3 EC. Coco Brand are Canna A&B

Exactly, sounds like she is getting too much in the nutes department. Do what you want, but like I said, I would just do a many reset with a flush and start over with a more appropriate level of nutes for a three week old auto.

Good luck!

Hey, but no salt built up run off are same as i put in 0.9-1.0 why do you think to much Nutes?

1.0 EC is ok. She looks better for sure. Like I said, the general consensus on feeding for autos has been to start around 200 to 350 depending on water you use. Build up to 450 to 650 and then after week two in the preflower phase, you can start bumping them up to numbers like 1.2 and even 2.0 if the plant looks like she can take it and gets really huge on you. I have had plants that liked 2.3, but they were 1.2 meters tall and has massive colas bro.

There are always exceptions, but that's what I have been doing for years. If I push too early, I often get plants that stunt, burn, or start showing lockouts. They look pretty healthy now though from that last photo.

Good luck man!

That looks quite a bit better...

Leaves are overlapping a little, ususlaly means she is a little too close to the light as well, but the color looks good now bud.
