Gelato 41 & White Zerbert DWC

They are pulling through. I have began treatments for the spider mites and I am still having some good growth. Hopefully, I can keep them at Bay since I caught them early. The Gelato has the most damage, but is also growing faster than the WZ. Both plants have been topped. I increased my lights to 50% strength. There were some brown leaf tips from last week showing some nute burn when I used 75% strength nutes. This week I dropped it to 50% strength, I will keep a sharp eye out for deficiencies since the ppm is down to 440.
