grownow said:ohh i get high with a little help from my friends (what an earworm)
hi
my leaves are curling and i dont know what it is ..i dont water them too much ...they dont have to much heat ...
What substrate/medium are you using? What brand of soil mixture are you using?(percentage of perlite, vermiculite...etc?) compo sana with ca 75 percent perlite
What is the pH of the "RUN-OFF"?started with 6.5 ...dont use ph ,ec
What size bulb are you using? 250 watt
What is the distance to the canopy?30 cm
What is your RH Factor? (Relative Humidity) ca 58
Is your water HARD or SOFT? hard
hi grownow,
75% perlite means you have to lower Ph to ~6 for optimum uptake.
Your hard water makes things even more difficult for lowering your PH.
I would go with 40-50% perlite next time.
Your new problem is caused by PH being off OR by low levels of
P / K / Microelements.
Get a PH meter soon, cause flowering is a different ball game.
Your lights could also be closer than 30cm, but i guess your temps would get too high. It would help though.
Good luck
p.s. Like MyNameStich said, i would not flush. Just give em a small dose of PK and microelements. Increase as needed
