This is my first grow. My germinating went great 100% everything was good till about week 2 i think. 2 plants started drooping so i held back on watering ( i water mornin and night with a mister bottle aboit 3 mist to the surface. And mist mid day as humidity was low) i think that along with my 85 degree temp caused a potassium deficiency. Leaves are turning yellow from bottom up. Still feel waxy. Stem strong. Also i have tomatoes in on the same shelf they were doing great then boom leaves purple. Everything online say same deficiency for them. This morning i added bio root to them aboit .1 ml per 12 oz idk im fishing here. Like i said its my first grow. Any help? Also im using a 60 or 100 w replacement cfl. Three for the shelf one over the cannabis

Strain; northern lights/ bag seed Soil in pots; using jiffy organic seed starting mix System type? ? PH of runoff or solution in reservoir? Havent check. I doent watee till run off. Should i? What is strength of nutrient mix? 1-1-1 bio root Indoor or Outdoor Light system, size? Indoor in open basement room. With a/c to room. I think 13 w 6500k cfl about 4 inches away but was in a upstairs closet Temps; Day, Night day high of mid 80s night around 68 Moved to basement and night was 64 Day N/a Humidity; Day, Night 55% to 30% Ventilation system; Yes, No, Size no but had a fan by closed door blowing towards plants AC, Humidifier, De-humidifier, Co2; no

You don’t put a number down for pH…very important to know that. What type water do you use? Tap, well, distilled, spring, rain, ro? [image]

Thanks for the reply @kabongster. To be t i dont check my ph everytime. Probally 2/3 of the time i do. I take it down. To about 6.5 using tap water. Sometimes it sits others it doesnt. I mix in a medium spray bottle and may use 1/3 on plants. I have about 40 seedlings im also growing veggies for the first time this year.if read to water threw does this need to be done. My soil has been separating from pots is that bad? I have the ph tools but not the thermometer.

Also i have moved the setup to a basement. According to the chart i was causeing the deficiency of zinc. I had bad air circulation, ventilation, temp, humidity, and not draing threw the bottom. should i put rocks i. The bottom from now on?

If you had it in the seed starter, the multiple soil mistings every day might have led to over watering and that led to the nutrient deficiency. The mix probably had something to retain moisture in it. Fix any drainage problems…learn what your plants need. “My soil has been separating from pots is that bad” what’s that mean?

My soil feels dry on top even had some seeds not germinate so i stuck my finger to the bottom and soil is cool and maybe damp but not wet. And soil seperating is a sign of dried out soil correct? But with a nute deficiency water may not be moved threw the plant, it stays in the soil and suffocates the roots giving signs of ovewatering. With the high temp low humidity my stomata? Would be open or closed i forgot which and sweating K. I think this is the problem. I think iv adjusted well temp was 72.5 at canopy and humidity was 59 after 6 hours on. So hopefully with a better environment and some bio root they will pull threw 4 of 6 look bad. But we shall see in the end. And try again.

It sounds like you know what to watch for. Get the babies watered properly, allow to dry, watch your misting…if you’re worried, put a humidity dome over them.

under watering has many of the same symptoms as over watering if all you are doing is misting soil twice daily you may be under watering do your pots feel light? best way to avoid over watering is not to mist but to water from the bottom. Adding water to their trays let them soak it up then remove extra judge by weight if they feel light water heavy don’t if they aren’t getting enough water they won’t eat and will droop and stop growing.
