Problem with my very big baby

[GEORGE]

Think I'm going to flush it with just water for a week then start again and spread 2ml of each part over the course of the week as well as raise the light another 6 inches and ill update the post if anything gets better or worse, hoping its not too late

No way your light is burning your plant at 20". JMO

Run 5 times the pot size of water into it. She has way to much nutes in her soil. We use the same nute line. After the last transplant i wait 2 weeks before I start to give nutes. But when I start i start with 33% stg. Even 1/4.. and build my self up slowly till i hit 66%. Not going any higher then that. And that is in week 5 of flower ish.

Flush her 5 x amount pot size. And next time you give her 33% stg feed.
Correct stg for you will be 0.45ml micro/l. 0.9ml grow/l 1.3ml bloom/l.

Next watering after the 33% is just plain water. Then next watering after that 40% stg feed. Theb just water next. 50% and so on.

Can we have a picture of the plant? Not just the top?
I think 50% stg is more then enough for you. JMO

IMO you only need to flush with 3x the amount of pot size. Lot less work.

Flushing is probably the best thing you could now before you get too far into the flowering state.
After the flush you should monitor the strength of your nutrients from there on. If you don't have an EC probe then you might think about the small investment. I can't grow without one. I always know or test the strength (EC) of my nutrient solution before I feed it to my plants. What's on a product's dosage label may not be what you think you are providing to meet your specific plant demand for nutrients.
Thanks for sharing your grow with the forum.

You are correct.

The light is 1000W true power? if so, maybe it is too powerful for these plants. seems like light burn to me.

[GEORGE]

Just so you know, that light pulls 110watts from the wall with an advertised 2.7umol/J efficiency.

Cheers

Not 1,000 Watts What Barney said^^^

Hi guys so its been a few weeks since I posted about this problem, I've flushed the plant a week before starting again with feeding on a much smaller scale, the burnt leaves only got worse over the next 5 days while flushing as it mighy have had a build up of nutrience in the soil even after i flushed 5L of water through the medium straight away.. I had to remove the 4 top fan leaves as they were too far gone and was just blocking the light more than doing the plant any good, I know you shouldn't prune during flowering (so I've read) but it looks like its recovered from the prune.. now I'm just waiting for leaves to come off with the slightest touch before removing them, so all in all it looks like its recovered, but let me know what you think.. also I'm getting some white fluffy mould on the tips of some leaves where the burn has got to, I try to keep this mould off to hopefully stop it spreading, failing that should I remove the affected leaves? No while fluff has reached any of the buds and I check on it daily so I'm checking to make sure they don't even get close, I've had to remove a few more leaves that were just again too far gone to save and doing more bad than good, any advice as to what I should be doing or does it sound like I got it covered? Currently on week 4 of flowering, another 3-4 and it should be finished

Removing some leafes during flower is all fine. Many people do a big defolation of the undercanpy after the strech when starting flower.

Do you have any fans blowing in there?

She is a big girl You must water her often since she is in a small container

Follow the chart on the back on the nutrient boxes for flower. She needs alot of PK in flower. Since she is so big i would maybe give her 100% stg from the bloom and 66% from micro and grow. Do you have any other PK boosters? Like Bigbud and so on?
