Just at 5 weeks in, and I've been having issues in the last 1.5 weeks or so. I definitely nute burned the far right plant 1.5 weeks back, but now its also seemingly hitting the other two (albeit less strong). I also screwed up using the wrong set of nutrients for too long, but I'm now lost as to what's going wrong given it's my first grow. Desperate to figure out how to course correct. The plants themselves have tons of bud sites but I'm concerned if I don't fix it now, it'll eventually kill the plants off.
Feeding the ILGM series of nutrients at half strength or less, full 18/6, constant airflow + C02 and ventilation. Water PH'd to between 6.1 and 6.6,
What do? No clue what's wrong because I don't have the ability to measure individual nutrients in the runoff, but the symptoms aren't clearly one thing or another to my untrained eye. Thanks in advance.
You most likely have a salt build up in your soil from over feeding.
Hypochlorous acid or Athena cleanse will help break it down. Lactic acid bacteria helps with organics. Other than that, drop the feed, give her some water soluble calcium and Epsom salt with her watering and drop the nutrients a bit.
Thats overfeeding, heavy, plus definitely ph swing and maybe even lockout.
I see N toxicity, P necrosis. If plants still drink, then no lockout, just ph and overfeeding, if stopped drinking, soon heavy paling will start.
If coco - flush, load WAY less in.
If soil, no feeding for 2-3 weeks, only right ph and good watering regime, aka wet/dry cycle for roots to get oxygen
do you have guaranteed analysis labels? then, you have the ability to know what you feed per nutrient. there are online ppm calculators there's an app i've seen that can help, too. Symtoms overlap. Diagnosis based on what you see is only a "sure thing" when you also have familiarity with the products and some focused expereince in general with playing around with fertilization levels. hydro/soilles nutes -- 1-1-2 ratio fo rnpk and 4-2-1 K-Ca-Mg are good starting points. You still need some trial and error to fine tune it, but it'll get you there faster if you start here. 'soil' nutes that rely on microbes to get N plant-available you shoudl go with 2-1-2 for npk - basically it builds up a non-plant ready level of N in substrate for the microbes to work on and provide enough to plant per day... per week whatever.. over time. Things to consider -- light burn if only at tope (the interveinal damage) .. if not light burn, looks like a boron deficiency which would be very unlikely, so ph or nute lockout becomes a possbility. if you have switched to a "bloom' formula, i'd wager it's too high K or P, because the plant uses roughyl as much of both of those in vege as it does in flower, despite common belief among the peanut gallery.
