I now understand there might have been a slight misunderstanding about feeding and schedules etc. I guess I didn't explain properly or thought/assumed everyone is aware how these systems work. My apologies. The coco will never be dry. The system recycles the water from the reservoir top and it...

When the reservoir starts to be close to empty. The first 2 weeks of veg it was once per week and now 2-3 times per week

The leaves look completely normal underneath. New growth shows a tiny bit similar symptoms but only on a few leaves. I give H2O2 as the bottle recommends. Usually 1ml / liter. 2-3 times per week. (They have started to drink properly only now, so previously I had to refill the reservoir only...

I just use the guide from Advanced Hydroponics Of Holland

How is your grow space temps and humidity?

Growing 3 of my fave strains right there, and interested to see how your Ayahuasca Purple progresses as I have that same in the works atm :peace:

Sorry for the extremely late reply. Still very happy and pleased with these lights. And yeah. I got to spend a couple days with the founder and one of the workers from the company last year when they were having a seminar about LED grow lights and such. Great guys who are passionate and doing...

Update: Looks like it was a nutrient lockout due to incorrect ph. At first I tried to lower the EC and when it didn't work I tried to raise it as instructed by drsaltzman. I monitored the progress for a week or so and the problems just continued and worsened so I bought a proper PH-pen. PH...

Interesting. I thought that when I check the ph when I mix the nutes and later check the runoff and they are both fine I'll be good. I will be investing in a quality PH pen tester to get more accurate readings and take them more frequently in the future then.

I have two SANlight EVO 4-120 lights. Currently dimmed to 60%. https://www.sanlight.com/en/product/evo-4-120/

I'm hesitant to up the feed when the runoff water last time showed EC of 2.4, even when the max I've feed her during the veg has been 1.4-1.5. What could cause such a difference? Also, I can't really understand why the PH is so stable while the EC swings that much... And as far as I understand...

I've been using a drop ph tester. While it's not the most accurate tester, I know that the value is above 5.5 and under 6.5 and the closest color I get constantly is pointing to ~6. The nutes are stable and I've used more or less the same amount of ph down to get to that value for years. I test...

I don't see things getting better. More leaves are starting to get rust spots and I don't see much if any of that healthy darkish green color. I think I'll just flush the reservoir and start from a "clean slate". Only questions is, should I play it safe and give them say half the nutes as...

I've raised the lights up a bit. Raised the daytime humidity to around 60-70% RH PH is ~6 and EC is ~1.4 Added some CalMag Yellowing is still continuing and some brown spots starting to appear on the leaves. I really don't have a clue anymore what could be the problem. Gonna wait a couple of...
