Growing 4 ptlants indoor; Hydroponic Ebb/Flow System
Plants were started and vegged in RockWool for 8 weeks then moved to bloom cycle 13 days ago. HydroTon is used in the grow tray of the ebb/flow system surrounding the rockroll.
Nutrient application; for the last 7.5 gallon reservoir change the following nutes were added:
210 ml Botanicare Pure Blend Pro Bloom
70 ml Botanicare Instant Karma
70 ml CalMag
9 ml Bushwhacker (will be last feeding with Bushwhacker)
400w HPS, 1 ft from plants
Temp: day cycle 75 80, Night Cycle 70 - 75
Relative humidity: 35%
Light Cycle:12/12
4 in. exhaust on light, 2 intakes, 1 main exhaust, and circulation fan.
When I initially moved my 4 plants from veg. to bloom, I had some heat issue during the light cycle for the first 6 days; temps were in the 88 - 92 degree range. During that period (heat problems), I noticed some rust spots on some of the larger, lower fan leaves and the new growth, near the blooming buds, curling under.
After fixing the heat issues, the rust spots stopped (damaged leaves were removed) but the curling doesn't appear to have been corrected.
My suspicion is overdoing the nutes, but wanted to confirm with the pros before my next reservoir change
Any help is greatly appreciated. Pictures below.
