This is my first grow. I needed something very stealthy so I'm growing in a 16" x 9" x 36" cabinet. - Simple hydroponic system. Basin filled with about .75 gallon, small air pump and air stone. - LED is 216watts (UFO full spectrum) - Wifi outlets for control and timer on fans and LED. Also have camera so I can always have eyes inside. - Crop King Seeds - Autoflowers - White Widow and Northern Lights. Read that these are good for beginners and smell isn't as strong as others. - Germinated using paper towel method. Soaked 18 hours, after 3 days put taproot down in soaked (spring water) jiffy pellet. Kept dark for 48 hours. - After sprout, began 18/6 light schedule. No nutes for first week. - Per instructions from the cabinet maker, I mixed 1 tsp of Maxigro in 1 gallon of water. After 1 week, I added 1/8 cup of this solution into the basin with .75 gallons of water. (Seems like a very small amount of nutes, but said go slow). -PPMs are stable ~400 since feeding started. -Added 1/2 cO2 pellet during week 3. -pH was high during first week (as high as 8.3) but have been controlling with GH pH down since. Avg 6.1. -Roots look healthy. Changing water in basin once a week. Using syphon to drain. - Started LST. NL has been growing faster, was able to bend an expose to more light. Sorry, no photos for first 2 weeks (just found this site!)

The plants colors look healthy and about 8 flowering sites appearing on NL and 3 on WW. However, the leaves, particularly on the NL look to curl under. I've been having little trouble keeping the pH in the 5.5 - 6.5 range, seems to drop to the mid 4s daily, but fix quickly.

@bmvape In order to diagnose your plants you need the right information! Plants have 2 types of nutrients called mobile and immobile nutrients. Immobile nutrients CANT be moved around the plant and due to this the symptoms show directly on the newer growth where the deficiency is active. The other type of nutrient is Mobile. Mobile nutrients can be pulled from the lower leaves to be given to the newer growth up top as a survival method so they show symptoms on the bottom side of the plant first. Your plant is experiencing a SEVERE case of Chlorosis(Yellowing) and Necrosis(death) in the leaves. Its obvious that your plant is dying some Nutrient deficiencies, but what might not be so obvious is why. You mentioned replacing the water in your basin - doing this lowers the Nutrients in the water and replaces it with more water! This is not good! Never swap out water without replacing the nutrients! To better help your plants recover you will want to replace what the plant drinks then PH the Basin to 5.8 EVERY SINGLE DAY. Then Once a week swap out ALL the Basin with more water+nutrients. This is the ONLY way for your plant to recover and if you do this she will recover.

Regarding flushing, specifically in hydroponics - should you do 48 hours of darkness during last two days of flushing, and should you deprive plants of water before harvest? (if so, just drain basin?)

In principle, the 48 hours of darkness are meant to signal to the plant that it reaches the end of its cycle .............. Regarding the rinsing, I recommend that you Flush 4 days and then give 48 hours of darkness ........... ..)
