OPERATION EIHWAZ

Yeah depending on your grow area, the deflection angle (vendors do mak'em diff) of your LED lamps, a light that size should be up further at least 30".

Your plant looks great. The only thing I would suggest is to bring your pH to around 6. And also when growing in coco it is best to give feed with every watering since it is basically hydroponics. Good luck with the rest of your grow!

If you look at the Flora feeding chart the max ppm they recommend is 900 ppm. I suspect your ppm meter may not be working correctly because your doses don't seem that high. I would check the feeding chart on their website. You should never have to exceed those doses. Good luck!

Personally, I water to achieve a 10-20% run off (I use soil, however, but same principle). Taking your reads from your run off is pretty important... What we put in is not necessarily what comes out. That 6.0 may be 5.0 in the run-off if there's a pH maladjustment or many other factors, like poor microbacterial health, pathogens developing and so on. It's extremely important (in mine and many others opinions) to test your run-off constantly to ensure everything is Kosher. If putting in 6.0 yeilds a 5.0 result, lets say, it's your indicator that something's wrong and needs an adjustment. Left unchecked, problems will start to occur. Just my two cents. Good luck this week👍

Are you flushing with water or nuets? If water there is something in those pots you have to keep at IF these reading are correct. Runoff should be within a few hundred PPM in to out. Tap Water would be oh 100ppm-ish so your run off will be very low flushing with water. THe coco itself will give you 100ppm, so a water only flush would finish when the ppm hit about 200-ish. If you are using nuets to flush, actually that is a better way to do it unless there are problems, 900ppm going in having 1300 out would not be out of line. But 4900 is yeah thats really dangerous IF the reading is correct, they do get a little odd at high readings still it was high. 900 in 900 out is pretty much flushed. You should be ok BUT How did it get so high? Do you go to runoff each time?

Hey bro :-) I would not remove any leaves :-) the plant looks great 👍 just a little dark from probably too much feed. But still great 👌. At the next pour I would only pour with pH corrected water and Ec to 0.4 with Cal / Mag, and the following times with a quarter Ec dose :-) then watch and enjoy 🙏🏻🌱😎
