Quickly answer these questions because it's rpetty blind to diagnose atm. -Pot Size - Soil -Water Ph level -Type of lighting -Tempature -Watering Schedule -Ventilation / Total number of plants in a room -RH (relative humidity) My first guess would be ph lockout on your water. Nutes are not getting to your plants. Try for around a PH of 6.5 and your runoff should be within range for a healthy plant. It's a common problem and easy to rectify with a ph pen/strips or dropper
Also get a magnifying glass and check for bugs. I don't think you have a problem nor is it due to the discoloration but just a hunch. PS : What nutes are you using and how much per liter along with your watering intervals
thanks for your fast reply bro, really appreciate it man really, but im a pretty good growing except that my pH is always jacked up. i just watered my plants right now and the run off is showing a pH of about 6. im using 5 gallon pots, 2 plants, about 2 feet tall, i water when i feel no moisture when i put my finger in the soil, im using a strong 120mm fan that's pushing out and a room fan that's blowing on the plants as well. im using a 150 watt hps with side cfl lighting. im also using FFOF soil with extra perlite and the temp is about 87 and the humidity is 63%. and i am severely stoned..... hehe
Def ph...its way to low... get it fixed ...with that soil you wont need nutes for a while and with proper PH you plants will be gorgeous man...
so how do i raise the soil ph? do i use i high phed water to bring up the low ph or do i keep watering with phed water?
