I’m on my first grow.
Multi Strain (6 Gelato, 7 Grand Daddy Black, 1 Blueberry, 1 Northern Lights)
Grown in 70/30 coco/perlite
1 Mars Hydro TSW 2000 400W LED
3 Cheap Holland Star “1800W” COB lights (probably 350W each)
1 Aglex “2000W” (actually 480w) blurple/COB combo.
In an 8x8 tent, with an auto fertigation system.
Feeding AN CoCo Connoiseur. Adjusting PH down to 6.0 (I know I’m not supposed to, but with PH of 6.8 without, my plants we’re having all kinds of issues.)
Input EC 1.5, output EC 1.1
The grow seems to be going well, but I’m worried about some burned tips that I’m seeing on just a few leaves. They’re not big right now, but I don’t want them getting worse. I’m thinking it’s light, not nutes. They seem to be thriving.
My question is should I flip or is this a big deal I should try to fix
With 1.5 ec (750 ppm) going in and 1.1 ec (550 ppm) coming out would suggest she’s hungry. Some of it is really hard to tell because of the grow lights
I was thinking they might be hungry too. I wasn’t getting runoff on two of the plants that are burned. I Went from 3x to 4x daily and they started to runoff. The were two of the biggest plants and I thought they were maybe just drinking lots, having more roots.
No. It should be in the 5.7-6.2 range from everything I’ve read. But if I don’t PH down the “PH Perfect” solution it adjusts itself up to 6.7-6.8. AN says not to adjust, but I’ve had issues when don’t.
Anyways, I had some spots today that tell me it’s Mag. So I’ve added some Cal/Mag and will foliar spray w/Epsom salts. Fingers crossed…
It looks like you may have a vpd issue, which can definitely make your feedings go screwy. I don’t feel that what you’re showing is light damage, mostly because you have some showing on lower parts of canopy. That’s not typical of light damage, which is usually worst at top to nonexistent at bottom of plants.
Just a thought, but just because your ppm is relatively low you’re still feeding 4x a day.
