Does yellow leaves with red tips mean my plants need more nutrients or less? Jacks 3 2 1 on Auto

is that fuzz on the perlite? if so, it's fungal infection of some sort. If you aren't adhereing to a wet-dry cycle change habits immediately. The concept of watering ondemand is misguided most of the time. Ensure pH is proper for your substrate, i'm assuming soilless. ~6.5 is what jack's will likely amount to. The way it has progressed week-to-week makes me lean lockout more than deficiency. If you do wait for top layer to dry and fully saturate when you do irrigate (with 20% runoff, fertilizer each time), then you can fiddle with nutes. Otherwise, fix your irrigation habits and ensure proper pH, then re-assess after a proper wet-dry cycle. jacks is a full feed.. if you are using in soil, that can work too, but don't fertilize each time. That's a soilless best practice, not soil. soilless -- wait for it to dry, feel weight, get comforatable with that light weight. Water until 20% runoff each time. Fertilize each time... Soil - 6.8pH, but i wouldn't worry about jack's ~6.5. Same concept with wet-dry as above. learn weight. When irrigating with water only, ensure full saturation, but you don't want a tone of runoff... make sure no dry pockets exist. When fertilizing, similar idea until you have ramped up to "full strength" (whatever that may be relative to context, for example, autos won't be 100% dose for 'full strength'). Once the soil is sapped of nutes, when you fertilize you should shoot for that 20% runoff... stick to normal hydration as previous when not fertilizing. whether you do every-other or every third fertilization is personal preference... possibly the plant will dictate one. with autos, i'd wager every-other is better as you can lighten dose a bit.
