experienced growers, Please help me!

I have 4 plants under a 12/12 250 hps. All are in sec week of flowering. I water every other day. alternating molasses/epsom salt and bloom fertilizer. These chlorosis of leaves is spreading rather fast. I need to know if I'm missing something or what. I was thinkin it could be a nitrogen deficiency, but it also looks like a magnesium deficiency. I just started the epsom salt/molasses water 4 days ago, but i noticed this about a week ago. Do I need more time for the epsom and molasses to help or what? Please if anyone has seen this before, what do I do?

These pics are from a week ago...

When in doubt, flush your plant. The worst thing you can do is over nute your baby and it is a very very very very very common mistake.

I would forget the molasses and the epsom salts. I never have given my plants all that shit. If ya keep it simple then you will grow nice buds. Use a blooming nutes. They look like they need some nitrogen.

Just flushed week ago, I am using bloomin nutes, on alternating feedings. So you think its the start of a nitrogen def? I know its in an early stage, but i wanna figure this out before it becomes a bigger prob. I may add a tiny bit of veg nutes to my watering, to bump up the nitrogen levels.

So what you mean is add it up and lower total dosage to match my ppm? no prob. thanx

If ya just flushed them then stick with the basic nutes and not the other stuff. A little nitrogen boost will not hurt.

Don't really want nitrogen in the flower cycle. Molasses is good. I use about 1/2 tsp per gallon and 1/4 tsp Purple Maxx.
Be sure and just use water and flush good for a couple days first. This is the most common mistake for new growers. Too many and the wrong kinds of nutes. Use the KISS system till you get more proficient.

Hey wheeler be careful with adding a lot of stuff to your soil things like Mg deficiencies are very rare and the symptoms can be similar to micro-nutrient toxcicity. I agree with the others flush your soil with clean water and watch the new plant growth for a few days if it appears to be healthy stop you current feeding schedule and start back few days later with at a reduced strength. Make sure you check you soil and water PH as well if incorrect this can cause nutrient lockout. Remember that the damage is done on those old leaves so your best indicator of plant health is new growth. Good luck bro keep us updated!

Ok, well this is just happening to the middle leaves, and i did flush right after I noticed. about a week ago. All new growth looks very healty and buds are starting to grow. None of these sighns are on new growth, just the middle fan leaves. I would rep+ u but it wont let me again, yet. But i'l get you. Thanx again. Mayb I'm just over acting a little.

Looks like the flush was right. You may have locked out some nutes with too many other nutes. For me yellowng is from too much water, Not enough N, Or my latest, bugs eating the roots. More than likely you locked out your N somehow. After the flush I would gve them a dose of your grow nutes. Killerweed isnt exactly right. You want N but not a shit load. You pretty much give half strength N unless the plant show signs of needing more. Like yellowing. It may be strain related. My Orange kush needs lots of N unlike my other plants.

Give them half bloom half grow and gradually cut the grow and add more bloom. And then at the end (last weeks) you will just feed water. What has your ph and ppm been? WM

Thank you WM, My ph has been at 6.8, all the way thru the soil. I will flush again, and does as you instructed, Thanks again!
