Hi guys, brand new to growing. My plants recently started showing these burnt looking tips in the last 24-48hrs.
I’m growing in organic soil which has proven to been a pita regarding run off ppm readings.
My PH was running a little high around just over 7 so today I watered at ~6.7.
According to google images this may by a potassium deficiency but my higher PH may have caused that? I should note I used calmag 3 days ago. Today I watered explicitly for some good runoff to try to get back to square one.
Any input is appreciated. I found myself staring at several issues online and at one point or another they all looked like they could be it. Tricky business.
Input PH I’ve been tapering down the last week or so. I was around 7.5 from the tap. Reading yesterday was 7.1 and I watered with 6.7. I don’t know if I need to taper down for the safety of the plant or if I’m hurting it by not getting it in the zone faster. My goal was to try not to shock the plant.
As far as PPM Ive read that organic soil can tamper with the readings. Any truth to that? One is at 800 out, another is at 1400 out.
I water every 2 or 3 days, depends on dampness when sticking my finger in. I’m waiting for it to be dry. This organic soil is so dense/compact. When I do water I water until I get about 1.5 overflow trays worth to dump. Make sure they’re done leaking out and put them back in the tent. I’m using half the recommended dose of calmag once a week and half the recommended dose of a citrus feed (jacks classic citrus feed).
I have little gnats that fly around. I have the yellow sticky traps and it seems to catch them. I’ve applied neem as well as diatomaceous earth. They’re still present at watering.
With organic growing the soil should remain damp so the microbes survive. With the feeding routine you have with run off is more a synthetic fertilizer routine. That Jacks Citrus is 20-10-20, where this might become a toxicity/deficiency issue in flower is the nitrogen content compared to the phosphorus. Less nitrogen would be needed and more phosphorus and potassium in flowe. . This is purely and assumption and would recommend jacks 321, the NPK is 5-12-26 and you feed full strength from start to finish. The PPMs look great and the PH is at the top of the range. I would go in around 6.3 to get that closer to 6.5 and add 5ml of calmag. Keep me posted Grow Bro and target you feed and run off target 1000-1200 PPMs and 6.5 PH
Yes if the soil stays saturated. With fertilizer you use a drench to drought routine. With organic you maintain a damp consistency. The 0-10-10 is missing the needed nitrogen and if you use the 20-10-20 at 1/2 strength plus the fish shit the ratio would be around 10-15-20 which would be a better flower ratio. If it’s possible I would still recommend the 321 to eliminate any guess work or errors
I would encourage you to try fabfic pot and organic again. I promise its the most hands free stress free way of growing. The soil is your fridge. Its stocked when you get it for 30 to 45 days with nutes depending in your size of pot. You follow the feeding schedule provided with dry amendments like i have been and i guarantee you wont be disappointed. Check out my grow journal.
