I have.9 Super Skunk plants and they seem to be growing very well considering their less than 2 months from germination. Here lies my problem. The majority of them are showing some signs of pistils of very early flowering but 2 plants are very light green. I’m assuming it’s a Nitrogen deficiency. Their all in FFOF for 6 weeks with no nutrients yet. Have read different things as
to how long before need to feed in FFOF.I have FF Grow Big and Tiger Bloom and my concern is should I use the Grow Big to attempt to correct the Nitrogen issue prior to feeding Tiger bloom for flowering or go straight into feed the Tiger Bloom. Really need some advice on this. Also whichever you recommend could someone please tell me how you water when using nutrients? Do I saturated my medium when watering. Medium is 75%FFOF & 25% Perlite. Just don’t wanna mess things up as they seem to be doing well outside of just a couple of them. Is there a different product anyone would recommend outside of the 2 I have to help with the issue. Only my 2nd grow and pretty proud of how they’ve progressed and I hate to make a huge mistake at this point so if anyone could please help me I’d truly be in your debt. I’ll attach a pic and you can see the difference in the ones compared to lighter colored one in the pic. Also whatever corrective action recommended is there a general time frame it should take to see a result of the leaves darkening back to normal again. Besides any leaves that may not be able to return to normal again. Any help would be great and if anyone could please help me I’d appreciate your time and knowledge. Thank you.
this is the general timeframe nutrients are needed. 2 methods used to measure the nutrients in the soil. Run off or slurry test. Slurry testing is more accurate, every routine feeding should be to liberal run off with occasionally testing the PH and PPPms of the run off
