Medium/grow method: Fox Farm OF/Pumice 75/25. Using Autopots with Airdomes, Hydroton

Feed: and supplements used: 6 gallons water 6.5ph, Megacrop 2P, A 12.5g, B 5g, Power SI 3ml, Massive Bloom 12ml, Drip clean 2ml. .7ec 1000ppm

Water source: Filtered Tap 170 Ppm

Strain/age: HomeGrown Cannabis Co, Dee Lite 5/15/21 Approx. 71days

Light used: Mars Hydro FCE 4800 dimmed to 75% (300) watts, set at 13”, Light cycle 18/6

Climate: 77-83F /45RH, Leaf Surface temp 82

Additional info: Nute Burn, heat stress, magnesium and or phosphorus?

I have mixed a foliar spray and used it twice over the last 5 days, uncertain about whether I can say I noticed any difference. 1qt water, .5g Kelp, 1/8tsp coco wet, .75g mc part b

Did you send in a report since you have had no response?
How much and how often are you giving them plain water?
Perhaps with the Fox Farm and your feedings they are being overloaded? Maybe try just plain water for a week.
Also raise the lights, 13 inches may be too close to the plant.
Hopefully someone with more knowledge will give some help.

Hi mate, Ive seen the report you sent. It's still there waiting for someone who can action it and give some good advice.

It looks either hungry or nute locked out to my eyes ... but i don't use MegaCrop or any of the other products in his lineup (or the soil) .. so it's best to wait for someone who can answer with some degree of confidence.



Hopefully it will get picked up soon, but be aware that it's all voulantary from staff members accross the world, and people come on and help when they can (along with their real life duties) and there aren't many infirmary specialists who can give really solid advice.

^_^

I am a stoner and I don't always see these posts since I sleep.

@cloud10 Whenever you mixed vendor lines you risk lock-outs. FFOF has preloaded Dolomite Lime and calcium can fast become overloaded. You are locked out but I am not sure which nutrients are causing the problem.

I looked up Massive Bloom. NPK 1-2-3. Power Si by itself is not a problem as long as it is well mixed into your water long before you add anything else. If you add it after your other nutrients it will lock them up!

As you can see in my calculations your Nitrogen is very high before adding the Massive bloom. Calcium is high and the Magnesium and sulfur are low. They are so low that this could be the problem?

FFOF does not respond well to flushing so the best thing to do is just try to feed balanced nutrients from here on out. Try to keep them in the 550 PPM range not counting your starting water.

This is what I would feed.

@cloud10 another thing I just noticed is the use of clay balls. If you did not buy the good PH balanced Hydroton and instead got the cheap ones you may have a PH problem that you will not be able to fix?

No I haven't sent a report, just figured it would get addressed eventually. No plain water, with recharge a couple of top feedings much earlier on. Seeming like I have messed up several things, LOL!!! Thanks.

Thanks for looking into the matter. I will read that, thanks.

Thanks for this recipe. I'm about to mix a new res this evening.

The clay pebbles are hydroton brand, I only rinsed them rinsed off when potting. I did just get a Blue Labs soil pen and it was 5.8.

Thanks again.

You are welcome.

5.8 is a bit too low for FFOF. It would be better at 6.4. Don't make rapid changes Just a couple of 0.2 tenths at a time.
