Let them root into the pot. not sure what soil you are using. they may not need nutes added for a week or more. quite likely that you should leave them alone. possible you overwatered which is a bad idea. many do this while learning. i did it recently by mistake (was tired) but things worked out ok. patience is a virtue as is seeking knowledge. the plant is forgiving and grows in a range of ph, nute levels, and climates but this is not a hard and fast rule because genetics vary. always good to start with seed/cuts that are not fussy
Easier for me to explain my approach:
Say a Seedling is in a 4'' pot
I fill a 2 gal with dry pro-mix ( a soil medium that is peat based, has no nutes)
I take water, do my nutes to 500 ppm then pour water in, mix the soil, add more water if needed
I get the 'soil' moist but not dripping out the bottom. i use clean hands to do this and make sure water is absorbed but not too wet
Reason: over saturated roots are deprived of oxygen and root disease can occur (done it, try to avoid it)
The goal here is to get the roots to spread throughout the pot
I leave them alone. I do not water them for almost a week. Sometimes more. This will depend on temp, rh, etc
guys will tend to baby small plants. ime 'coddling' them is not good
I can feed a seedling with 2 sets of true leaves at 1000ppm and put them under a 1000 w bulb at 36''/ 90cm
I don't recommend this as one needs to learn to 'read' the plants and understand them before 'pushing them'
I am not a zen master lol but i know some stuff about soil mediums and soil
If the soil dries out to much add a drop or 2 of liquid soap. the ionic bond between roots and soil is damaged, so to speak, by the soil getting to dry. Also, the lack of water in the soil will cause the nutrient level at the rootzone to go too high and leaf tips can burn
Do a lot of reading. there are many good threads on here. hope this is a starting point.
this is very important when cloning
I want to be helpful but really feel that all must 'put in' some time. by this i mean reading. a lot. this mj thing is way overcomplicated by many. ironically, it may take a lot of reading to understand what to do and why one is doing it to avoid pitfalls.
one member here, skunkd0c, recently shared some stuff with me about nft. it really blew my mind. so simple yet not used a lot from what i can see.
sorry, i ramble lol
