bbjack

need more info.... pics would help too.

just got pics up...my dinafem critical jack is doing great same nutes soil watering everything ...
SOIL.FFOF
LIGHT. around 300 watt of cfl
NUTES. big bloom, tiger bloom
LIGHT SCHEDULE. 20/4
POT. 6.5gal
VENTILATION. small desk fan and duel window fan

temps around 80...

is the soil always soaked and wet ? if not read this. mabe will help. looks nut burned but I don't think so I need to know the soil wetness first. kinda looks like root rot as well. tricky one. http://growweedeasy.com/marijuana-symptoms-pictures

its not always soaked i water once every 3 or so days depends on how heavy the pot is

It's clearly nute burn. For some reason these seem to be coming in a lot these past few days. You're growing small autos in a hot soil and adding more nutes to that soil. CFLs work but you need to consider that they don't provide quite as much energy for the plant to process and produce and convert those nutes, so they remain as salts in the soil. Take it to the bathroom tub and flush the soil really, really well. Then let it sit for four days. Yours isn't as bad as a few I've seen in the past couple days, but yours needs attention asap.

is 20/4 a typo? bc the second 2 are flowering.
6.5 gal might be a little on the big side would make overwatering really easy to do.
80 is kinda on the hot side as well some plants might be ok with it some not.
it is kinda odd with that clawing and burnt tips i would expect it to be really dark green but it's super light.

yes nute burn for sure...easier to get nute burn when you have hot temps..lower your temps to under 80 and dont add nutes, you have rich soil and never need to add nutes until the plant is around 8-12ish inches tall it will begin to lighten in color that is the plant saying feed me..you NEVER want to see 80, 80 will be ok here or there but thats the beginning of the danger zone you will come out with crap if you flower in above 80 degree temps indoors

btw another thing to note is dutch passion is absolute garbage..especially their feminized line...watch for hermies and dont be surprised its way more finicky than the one next to it

For two firsy pix :

[h=2]Nutrient Burn[/h]



Solution: Flush your system with plain, pH'ed water. Give your plants some time to recover, and start them with a fraction of the nutrients you were giving them before working your way up to more nutrients. Many nutrients come with instructions to feed your plant more nutrients than most plants actually need. It's good business for them if you use more nutrients. However, in my experience it's a good idea to view the feeding charts that come with nutrients as the maximum amount of nutrients and actually start with much less.



For two last pix :
Heat Stress



Solution: Find a way to lower the temperature and/or increase the circulation in the grow room or grow area if heat is the problem. Having a small fan blowing over the tops of your plants will help prevent hot spots from forming directly under your grow lights.
If your marijuana plants are just getting too much light, try removing some of the lights or moving your lights further away from the tops of the plants.
When learning how to weed, it's best to try to keep things at a comfortable room temperature at all times for optimal growth. If it's too hot for you, it's probably too hot for your plants.

yes its 20/4 they are both autos

for more info the jack is on day 54 flowering hard ... the bb is flowering just very poorly and youngs leaves start browning in the tip and by the time they are larger leaves they are scorched . its seems like the leave falls to a really dark green getting limp then getting hard and crunchy turning to a light brown ...bb is only 2 n a half ish weeks younger.......as well jack is taking nutes great i give her 2 tespoons of big bloom and 1 table spoon of tiger bloom to 1 gal every 2 or 3 waterings...( i water every 3 or so days so. im giving nutes to jack about every 6 to 9 days) where as this bueberry i havnt given her anything in over 2 weeks just plain distilled water
