Whats up everybody!

First time growing indoors with a hydroponics system. we're using a tek-5 8 bulb 48'' w/ 4 red and 4 blue bulbs. We decided to build our own drip system for this vegetative room. Our plants are about 16 inches from the light and get watered 3 times a day for about 15 minuets. We're using the florogrow system (micro, grow, bloom) in a 20 gallon resivour we have about 10 gallons filled inside. We mixed in the proper amounts according to the back of the bottles. These plants are about 3-4 weeks old. Notice in the pictues brown spots on the leafs and discoloration on some plants. We want to know what you guys think we could be doing better. The room is covered in mylar with fans that turn on if the temp goes over 84 degrees. We have a box fan on medium about 4 foot away from the plants. Its about 78 in the room constantly. We check PH daily and make sure its between 5.6-6.3 and keep adding distilled water to our 10 gallon line daily. Our system doesnt drain water amazingly.

Let us know what you think and we'll keep posting pics of our first grow :peace:

you have calcium and magnesium deficiencies, as well as a low p-k issue.

use cal/mag from botanicare from start to harvest, and feed full strength hydro nutes (ie, general hydroponics 3 part)
