Hey all, this is my first grow. The rest of my plants are looking pretty healthy except one. I am using a 400w MH lamp, Ionic Grow nutes (1/2 strength), Tap water (PH is about 6.5-7.0), Temp is 70-73 day, 65 night. I have tried doing some research and believe it to be either an Iron deficiency or the PH is too high. Iron deficiencies come with high PH levels I read. Any experienced opinions would be appreciated Here is the sick girl: Here is one of the healthy ones to compare: together:
Been doing some more research. Could this possibly be from temperature change? Thinking its either: High PH correlating to Iron deficiency or Temp change (70-73 day, 65 night)
I would say temp issue, unless you germed them in high ph wool, like +6.0 and up, for wool the best range is about 5.2-5.5
