You can see in a photo. They got ghe flora series nutes at half strengh yesterday and calmag 5ml per gallonAny advise?

Nitrogen deficiency pretty sure.

I've tried to give 2 litres of water with 2 ml of nitrogen, but it didn't solve the problem. Should I give more?

Over watering will only compound your problems.

You fed yesterday? Wait and see. Autos suck. You're seeing one reason why. No time for recovery.

i wouldn't be so sure about autos sucking...

lately i've seen many vigorous, resilient auto plants...

Oh hell yeah. Put it back into veg and let it recover.

Your point is proven, That's a trade people are willing to make when they get into autos.

I personally like to buy regulars and choose my phenos, raise mothers, and take clones.

Just saying that autos aren't as bad now-a-days as they were 5 years ago

That was four days ago.

I don't think that I'm overwatering, because I water when pot is lightweight.

Sounds good. I was worried you were talking about watering right after you already had to try and sort the nutes. That would just give you two problems instead of just the original one.

I also use the "feel the weight" technique (or wait till I see some drooping) for telling when to water. Works like a charm.

The plant started to flower couple day ago. Should I still give him nitrogen?

Looks to me like a PH issue. That will cause nute deficiancies as the plant can't absorb different nutes at certain PHs. I'd suggest checking the PH of the water going in and the run off coming out to get an idea of what the PH in the root zone actually is. Soil will naturally buffer ph to an extent, but if it gets off it can still cause issues.

Thanks for comment, I ph water from day 1 at 6.5, the run off is 6.5 +-0.1 on all plants.

Excellent sounds like your on top of that. It might just be hungry, it was just an idea based on your attempts to feed it already.
