Calcium, Magnesium or potassium? Please help ❤

Remember, when flowering the need for feed increases. So what worked in veg may not be enough for flower. Keeping that in mind also know that coco is greedy and likes to grab up your magnesium. Therefore, it is sometimes required to add some magnesium (without more calcium) using epsom salt at anywhere from 1 - 2 grams per gallon.

Definitely need to ease up on any nitrogen. Take a few minutes to read this over:

www.growweedeasy.com

How to Identify & Fix Cannabis Nitrogen Toxicity (with Pics)

Does your plant have "the claw?" The talon-like leaves that are bent at the ends are a sign that your plant may have nitrogen toxicity. Learn how to fix it.

Is that a different strain than the first pic? Got any whole room shots?

I see no need to private message, lets let others participate, for everyones sake.

I may have forgotten, I am in a lot of threads and I am always baked, but what lighting are you running? Watts per sqft?

I know you tagged 1000w LED's but they aren't going to be true 1000w. Read the tag where voltage is listed and see how many watts or amps it draws. (amps x volts = watts). Blurples tend to be misadvertised the worst and they claim a 90 watt light is equivalent to a 600 watt HPS lol. If you have a link to your light, or manufacturer and model # please post it. I want to make sure your lighting isn't spread too thin as the plants seem lanky from what I see.

Your lighting is spread too thin IMO, how much square footage is that? Those are 110 watt lights, poor quality (not being a dick, just speaking truth). Each light is good for around 2.5 square feet probably. Push the plants all together into a small area under 4 of those lights to get bigger buds and plants that aren't so lanky. A lighting change would be highly recommended, those are really junk and why your buds are so very tiny and internodal distance is long.

So these together arent even anything close to 1, 1000w? My rooms is 36sq ft seeing as its only 6x6, And the lights are roughly 18 inches away from the plants. What would you recommend, t5s?

What is your budget?

Lighting options that I would consider:

HPS, CMH, or high quality LED.

A single ended 1000 watt HPS is cheap and would really pull great results out of a 4x4 foot area.

A double ended 1000 watt HPS will cover a little more area, like 4 x 5ish depending on the reflector.

Four 315 watt CMH lights would probably be a good option but costly.

If you put four HLG 550's in there you could really rock that space, drive them a little soft.

Your budget will be the biggest factor.

I can always get more fans or mount them on the walls.

Fans like that won't remove heat, they just blow it around. An air conditioner perhaps? Or an exhaust vent setup...

HLG and Timber make some great LED's

On a budget this is a great option here

One might start with one really good light, put it in a corner and use a 4x4 foot area. Grow some fire and then add more lights later to cover more area.

When growing under LED you want a little warmer canopy temperature than you do under HPS. So instead of say 79F you want more like 83-85 F at the canopy. This is because LED doesn't produce infrared light like HPS.

Hello All,
I am looking for some help with a flowering issue that I am having. I have been growing organic for 3 years now and am having a hard time wrapping my head around what my issue could be. I made a new batch of amended soil at the end of last summer and it seemed to cook well, but instead of using oyster shell flour for a buffer I used dolomite lime and used a bit less peat moss and put coco in the mix to make up the difference to try something different. My issue has been about four to 5 weeks into flower my plants are yellowing. At first I thought it was the gnats causing the issue so I treated the soil with neem seed meal and BTI, which has largely controlled the gnats. When I introduced a few new plants into the room they have had the same issue. I gave one of the plants some Recharge in hope's it would help, but 48hrs later it looks worse.Yesterday I had an epiphany that my dumb ass should check the ph of my R/O system and my ph was reading 8.1. Haven't changed the filters in 6 to 8 months nor have I ever changed the membranes. Today I went in the room and they are clawing a bit as well.Any advice would be greatly appreciated.

I don't recommend mixing coco with soil. They are two totally different animals.

Obviously, fix your RO filter.

Check the pH of your medium, it's probably high.
