right guys please help i have a 1.2x1.2x2 grow tent with a 600w hps, i have a nice set up here but having problems. i am feeding my plants on formulex nutrients. the plants are 3 weeks old now and looking so fricking nice BUSHY. im getting yello eaves now at the base of the plants, NOT WANTING TO GIVE MORE FEED AS DONT WANT TO DO MORE HARM PLEASE PLEASE HELP
i dont do PH testing as im using top soil and pure water from a £2500 water purifier i have at work im adding nutrients to that so the PH is not a issue in this case
You are most likely giving the plants nute burn... i would lay off the nutrients until they are better and in the mean time just give them the pure water. It would also be a good idea to check the ph if you are worried.
the Ph is is at normall as using CANNA TERRA PRo. i have been testing it and seems to at its best, thanks for the info guys ill keep you posted
