To begin with the pictures that Iā??m going to attach are all clones that were started just shy of 3 weeks ago in the system. The situation however is this has been a re-occuring problem. I have now tried and gone through two failed crops and working on my third with this one. What is happening is that I start getting white tips that turn brown and even leave curl and browning on the edges of the leaves. It doesnā??t seem to start till they get to be about ~10 inches tall. The first crop which was started from seed from a swag bag got to be around 2 feet tall but by the time it got around to harvest the buds were like finger nail size and the plants looked like they would catch on fire in a moments notice (almost all brown/dried up leaves). The second crop was clones that got probably close to 12 inches before they started showing signs of the tip burn and edge curling/browning and it progressively got worse till I decided to harvest the slightly larger than fingernail size buds. Growth was slow on both attempts and I swapped them over to 12/12 light cycle with bloom at 12 inches. However, the tip burn usually started before I swapped them over to bloom. With this crop, 5 of the clones sprung up fairly quickly to about 9-10 inches and then rapidly deteriorated with the tip burn/leaf curling and browning. At the end of the first week I started noticing that the leaves were curling and there was beginning signs of tip burn with white tips. The 3 small ones however barely grew but the leaves they had were very yellow on the tips till the point of some of them being almost entirely yellow. By the end of the second week the small plants had barely gone anywhere with lots of yellowing on the leaves and the 5 bigger ones had excessive browning that started at the tip and on the edges. Iā??d also like to say that I started out with 4x T5 metal halides and the 4x T5 equivalent to sodium lights in the ballast. At the end of the first week I removed the 4x T5 sodium lights and went with the 4x metal halides only but didnā??t see any improvement by the end of the second week. I change the water every two weeks so when I changed the water this time, for the first time ever I tried reducing the amount of nutes (Ionic Grow) to 3.5 tsp/gal instead of 4 tsp/gal like the bottle recommends. Now at nearly 3 weeks (I trimmed most of the dead leaves off) the 3 smaller plants have almost caught up with the 5 big ones. The smaller plants also have mostly 5 leaf growth and the bigger plants have only 1 -3 leaf growth and they havenā??t hardly done anything for this whole week. Also the smaller 3 plants have darker leaves than the larger and generally look more healthy overall with the exception of white tips on almost all their leaves. Iā??d also like to mention that this is 40g resv. and Iā??m filling it to 35gallons. I have been keeping the water in the resv. at PH 6.0 every grow attempt Iā??ve made. Iā??ve always used the recommend nutes/gal. on the bottle and this is the first time Iā??ve tried nocking it down alittle and so far the plants havenā??t really deteriorated anymore but they arenā??t really hardly doing anything and the smaller plants are coming up slowly but it seems like their growth has been stunted from the beginning.

After reading through some posts on here I do now realize Iā??m maybe .2 high on my PH but I donā??t really feel like thatā??s the answer to all my problems. I tried looking at my water report online but couldnā??t find any pertinent information on the web other than what chemicals were in the water and that my local PPM is ~120. Also I wanted to know about my lighting situation. I have a 8 light ballast. I have 8x metal halides and 4x T5 red lights. What should I be using?? Someone recommended I run 4x metal halides and 4x T5 reds and Iā??m not sure if its adding to the problem or not, but like I said earlier Iā??m only running 4x T5 metal halides at the moment.

I'd also like to mention that there is a white clacium type buildup that shows up on the upper layer of geolite where the water level floods to.
