It’s day 36 and my new leaves are turning a little yellow on the edges,
Soil - Pro-Mix Potting Mix
Light - 5 100W Bulbs, closest one is 4" from plants - 18hrs under the lights
Nutrients - Last feeding May 11th (1/4 strength Green Planet Dual Fuel 1/2)
Soil was fairly dry to the touch, I gave her 1/2 cup of pH balanced water earlier today, moisture meter says 3/10 which is below the “Good” moisture reading.
What is your soil? Have you taken runoff numbers for pH and PPM? Are you just watering? Frequency?Your plant should be much farther along at 36 days. Something is off.
Throw the moisture meter out. After you water, lift the pot and get a feel for how heavy it is when fully wet. Then, wait until it’s completely dry to the touch, at least a few inches down, before watering again. When you say “pH balanced,” what pH do you adjust to, going in, and what are you getting coming out? I agree with @WickedAle, something is way off if they’re 36 days old. Should have half a dozen nodes and be starting shoots in the crotches by now. No sweat though, they’re still mostly green, and upright. They will recover!
Out of curiosity, what does your moisture meter read in a glass of water?
Pro Mix potting mix is an actual soil, not like the typical stuff people refer to as “pro mix” as in a soil-less medium. Your pH should be nearer 6.5. The size for their age and the drooping leaves lead me to believe they’re being overwatered, too. Let them dry out more and see if they look less droopy. Do you have a TDS meter to measure the PPM of the runoff, too?
Just water first, and only in a ring around it at first, not to runoff. It doesn’t need very much yet. Once those first two round leaves, the cotyledons, have completely yellowed, there’s still a lot for them to eat in your soil. Once they have a few more sets of leaves, you can water to runoff and get a PPM reading and see what’s what from there. But for now, I’d just water @ 6.5 pH. Which soil is it again? The Pro Mix “potting mix” I’m seeing had a time release fertilizer in it. Can you post a picture of the bag?
No worries, I bought time-release fertilized perlite my first go. The fertilizer in it might be a problem once you’re ready to flower. It might be way too much nitrogen for the plants needs once they are flowering, and could burn them and hurt the yield. Maybe not. You may be able to flush the fertilizer out of it before you flip. They don’t give any info on their site as far as N-P-K numbers. The “up to 9 months” part bothers me though. Might need to transplant into something else when they’re ready. That mix may not be compatible with the needs of flowering cannabis.
