Have a Massive Plant that is Showing Deficiences, 4th Week Flower

Why are my leaf tips burning? and some leaves are starting to yellow....

Should i use some cal mag? The buds are starting to get very juicy..

I have plenty of bat guano, gypsum, hi-mag, lime already in soil. I supplement with Nature's Nectar potassium, molasses, microbes, and ro water.
I brew my own microbes, so plenty of micro-life in soil. (brew consists of molasses, natures nectar and microbes.)
Molasses i put in about tbls when brewing, then dilute further.
Run-off at 7.4/ very well limed.
But the leaf tips are burning.

On all of my clones they are perfectly fine. My hypothesis is that since i am pushing the envelope with HIDS and co2 that maybe it is a cal-mag def since buds are getting so juicy.

The plant itself is about 1 year old. She is 6 ft and about 10 ft around, in a 15 gal pot.

I will try to get a pic but it's hard with HIDs blaring!

Help from experienced grower would be swell.

Pics would be nice, just finished flowering an old girl myself, of course she was root bound in her 7 gal pot, turned all yellow due to OVERFIRT , but still finished nice with over 20 colas...how much longer do you have to flower?

4-6 more weeks depending on how ripe i want this girl to be. I'd say i will proably flower for 5 more weeks. So that's 9 total, i'll start flushing on the 8th.

overfertilization

yeah 2 many ferts guess

I wanna see this year old plant. Shes gotta be a bush!

How could it be too many ferts? All the stuff in my soil doesn't burn one bit on all of my clones. I have 25 clones, no def.

I give my compost tea which includes 10 gal ro water a few additives, Europonic fossil fuel, nature's nectar potassium, great white, microbe brew, subculture-b, plant success. And 5 tbls molasses. I then cut my compost tea 1/2 and 1/2 with ro water.

Will try to get a pic for everybody later. Sorry my phone wont focus with these 1000 watters

Anyway it is mid 5th week of flower, 38 days to be exact.

Some leaves are still yellowing and i think i should trim some of these leaves off but not sure.

My new leaves are a healthy green but the tips are still a tad burned.

The buds are forming, proably will get close to 3 lbs. That is what im hoping for at least!

I just bumped up my nitrogen and has started to get my green back. I'm 2 weeks in flower but the reason why my plant was fading because of the shitty soil I had which was Sunshine organic......It would be good for a 2month grow and that's it.
If they are in old soil how are the conditions cause that plays a part?
I have been learning that N def. can look like too much N.....And in my case not enough.

man, just hearing the size of that girl, in a 15 gallon pot, a year old, man I bet if you were to throw her in a bigger pot with some fresh organic soil, she'd straighten right out.
