Did too high EC this?

Ahoy,
Never grown anything in bubbler, before.
Plant of the pic is 4 weeks old. PH 5.2, when it raises to 6, i drop it back to 5.2. Using AHH nutrients, 30ml Grow,15ml Bloom and Micro per 20 litres of water. Normally ec had been between 1-1.7
Yesterday i checked the ec, it was 2.7. Looks like plant is shrinking, not so healthy looking anymore.


As a first aid, i chaneged totally new waters and nutrients into reservoir.

And another problem is this another plant, in 10l Bucket with coco and clay pellets.


Too much nitrogen?



thanks in advance

up the post goes.
plant in the first pics is looking rly bad now. Plain water now in bubbler. hope she recovers.

EC is way too high. I'm not familiar with your nutes so I would guess a .8 EC would be much better for now.

If "bubbler" is a constant feed type device you are WAY to high with EC. Something under 1 is all you need. Monitor plaon water and change if EC rises. As/if plant recovers you will need to start feeding again. Good luck.
