New Grower Possible stunted growth

[chrisgca]

Hello everybody and Happy New Year,

it's my second grow of royal dwarf auto.

The first one was a disaster (I've done it all wrong). Now, I have light mix soil, 200w light and for fert I have HESI TNT Complex, phosphorus plus and Bloom complex.
This time is better. It grows faster than the first one. The problem is that I'm on day 55,it's blooming but seems to me that it stopped. No big buds except the top of the plant.

These are the pictures:





Besides this all the leaves have yellow spots.

Please I can use your advise.
Is there something wrong with the plant? Is it really stunted? What do I have to do?

Thanks in advance

Few q's for ye mate but it could just be the genetics. in the same tent with same batch of seeds with same soil mix and feeding schedule at start i've got a huge 3 foot bush and a 1 foot high midget that has shown signs of deficiency and stress all the way through.

What method do you use to pot up and when do you do it? what size pots for each stage?
When did you start feeding them?
What temps are the high and low in your growroom, do you have a soil thermometer?
Got a ph meter? what ph is the run off water when using straight water and again when you feed ferts?

Looks like it could be a cal/mag deficiency. What is your pH? That's the most likely cause and would need to know what it is before making any recommendations.

I had a look at yer pics again is there anyway you can take a close up pick of one of the big fan leaves with the marks on it, get it as clear as you can and in natural light. Just wanna see if those marks are maybe caused by Thrips.
