growing 4 hydro plants. germinated all the same time, only this one is giving me a problem. Week 2. I'm thinking of nutrient burn? 12 on 12 off. Any suggestions?
Welcome to FC @CheechnChong24 Don't worry we'll help save it
It looks to more to me like a ph problem rather than burn, the yellowing pattern and lock out all point that way.
What's the ph of your res at the moment? What nutes and at what concentration (ec/ppm) are you feeding them?
Can I also ask why they're on 12/12 already? or have I misunderstood?
While you're growing the plants to a size ready for flowering you want to go with 18-22 hours of light a day and the rest darkness, these long days will encourage the plant to grow in size, then when the plant has got to around 1/2 the final size the light hours are reduced to 12 hours on and 12 off to trigger flowering (buds).Thank you for your reply! Using Advance Nutrients -Grow, Bloom, and Micro. 2ml each/per Liter. These nutes supposedly prevent any PH issues. The PH reading is about 7.8
I guess I am a little uneducated with the on/off hours. What do you suggest? Thanks again!
