Hey guys I was hoping someone could help me out with this. I’m about 3 weeks into flowering with Trainwreck plants and all seems to be going well except the leaves are yellowing at a pretty fast rate below are the details of the grow:
Trainwreck seeds
50% Fox Farm Happy Frog 50% FF Ocean Forrest
750watt HPS in a Grow Tent
Temps between 77-82 Deg F
Fertilized with Tiger Bloom for the 1st time 4 days ago but yellowing was occurring before then.
They look hungry. Seem to be eating themselves. Try getting a picture at lights out so we can see them properly 
I have plenty of options for feeding them just not sure what nutrients it needs and I am afraid of burning them.
It’s all older leafs and not new growth that’s effected??? Cannabis plants do drop leaves and replace even when in flower. They look perfectly fine to me but I’m no expert. My plants look like yours do most grows with no ill effects. Hopefully others chime in with advice

What do you think?
Looks spotty all over hard to pin point location if it’s more bottom it would be mobile nutrient and at top immobile deficiency … have ya checked for pests?
More than likely it’s the ocean forest cause your issues. They PH balance their soil pretty well, but they use high amounts of guano’s which always burn plants. Personally I feel a 2:1 mix of HF/OF is a good ratio to not burn plants.
I didn’t see the spots. Phone won’t do close ups on the forum for some reason. Downloaded the picture and had a close look. The spots are not something I’ve come across but the worse ive even had was slight bud rot. Would pests make the leafs yellow line that??
So would you say nutrient burn??? I’m learning here 
there are no pests i’m thinking some deficiency as the leaves have started to become a lighter green than before does anyone know what nutrient is lacking?
My advice is to top it with some oyster flour or powdered eggshells, or you can make water soluble calcium with the eggshells and some apple cider vinegar. It looks to me like she’s eating up the available calcium.
Calcium is one of the most overlooked nutrients that the plants need the most of, especially in flower.
New growth looks healthy. These leaves are giving up the last of what they have for the flowers. Late for a prune, keep feeding They hungry.
I thought so just didn’t want to give bad advice. Cheers @99PerCent
Thank you everyone for your help I’m glad I asked.
The spotty I was referring to was a spot of yellowing here towards top , some in middle and lower sections but not all over or more in one area as opposed to other sections but there is some speckling as well now that you mention it I saw it also earlier .
Thats why I kinda went that direction cause of different locations of the yellow plus the spot on the leaves when trying to diagnose things it always makes it difficult cause these leaves were probably turning 4-5 days ago and were just seeing it now.
I’m not very good with sick plants to be honest. I see yellow so I assume they want more food. I feed calmag every feed with megacrop so almost everything is covered. They just looked hungry to me but I thought I’d ask others to chime in instead of giving bad advice and killing his plants
That’s exactly what the batmix did to my plants too.
Too hot for them, they soon pulled round though.
So since your bottom leaves are probably like Esrgood4u. Said but it could be your water in them too much or your pots aren’t draining right check your dirt make sure it drains right and if it’s not that check your nitrogen and magnesium and sulfur levels different nutrient deficiencies can cause those problems read up on it on the diagnosis of it
Just out of curiosity, why would they start to burn into flower and not much earlier if it was the guano?
Unless they are newly transplanted are they @2ndtimearound? Learning here too as I would have guessed they either want cal/mag or a higher feed.
