This is my second grow and my first with 600w hps my light is about 18 inches away bare bulb wing reflector and all my plants are showing some unhealthy signs.... 1 is really starting to yellow badly and all 4 have lots of brown tips and brown/rust colored spots.... I'm only in the 2 week of flower... My first grow was from seed and these were from clones so maybe they are more temperamental..... Any input would be great if I had to guess... Calcium & nitrogen? Anyway I made a thread about 2 weeks ago and was told about maybe a magnesium deficiency... Let me know what ya think..... Thanks
Fox farm soil
600w hps wing reflector
Canopy temps 79-83°
Fix farm tiger bloom and 1 feeding of grow big at half a dose....
Yesterday I watered with distilled water... Also wondering if I should use PH down on my water last grow I didn't and everything was fine... Tap water I let sit out 24-48 hours...
I 100% recommend that you add calcium and magnesium with your water ESPECIALLY if you use distilled water. also, lower that high temp of 83. but you are also burning with too many other nutrients-this is why you have upturned brown crispy edges. The dots are from calcium deficiency probably becasue you used distilled water and didnt add enough calcium back. the yellowing between veins is probably due to not enough iron. and the yellowing down the sides of the leaves are from lack of magnesium.
This is a common problem new growers face.
to fix get a suppliment with calcium, mag, and iron in it and add it to every watering if you will be using distilled/ filtered/ RO water. if you use tap water then add it like 1/2 strength with every watering.
Stop using the grow big when flowers FIRST start to appear.. using grow big AND tiger bloom is probably what burned the tips. i would recomment adding either big bloom or sns 604B(My personal favorite for a tea) as an organic/natural tea to try to get a better quality harvest.
Lastly if your ph is off then you cant expect anything to get better. GOOD LUCK
(Just noticed you said you used tigerbloom at half dose too.. Tigerbloom contains cal/mag/iron.. so maybe you arent using enough of the tiger bloom but youdeff need to drop the grow big. too much nitrogen right now.. do you have any clawed/talon leaves? thats nitrogen toxicity and i would flush the excess N out.
