sup man,
if they are growing then you doing good, for a min there I thought i may have told you the wrong thing
if you got 1000 watter over them and they are that size you need to leave the 1000watter high up as they are still babies and you dont want to stress them with the radiant heat
I think this is whats causing the curling of the leave edges.
also 87 Deg is pretty high specially since they are just babies.
its better to be lower but I think it will be ok.
as long as your hand isnt too hot when you stand it over the plants feeling the heat of the light
What strain are you growing? i wanna give you a rough basline of ppm strength
ok so the stain im growing now is a light feeder. atleast from the previous strains I grew
so based on a light / safe feeding try to roughly stick by these guidlines unless you feel you should increase or decrease by reading your plants.
say up to 6" plants 300 PPM
Maybe at 12" plants no more than 500 ppm
shouldnt need to go any higher than 800 - 900 ppm
at the most hungry phase,which i think is at the streching period during flowering.
then once they stop stretching and begin to fill in thier buds you bring it down slowly using the PPM method and water drink thing i mentioned before.
but like mine are just finishing week 7 and my ppm is still at 600 PPM and i think shes a light feeder
so pls use the above as just a rough guide to play it safe but that could also be too much depending on strian
i use the water drink method and the ppm thing, right, to know how much to feed
but you also must use the leaf tips method. Your tippy tip tips of the leaves are the first thing to crispify when nute burn is starting. once i seen like the first millimeter of crisp burning on many of the leaf tips, you gotta back up right away just a lil on your nutes because thats the beginning of the nute burn. this is why its good to stare at your gurls and try to read what they need
when i harvest my leave tips are usually around 1 - 3 mm crisp and burned only on the very tips.
this is because I always give them as much as possible before they start to burn i back off.
