Yellowing off too soon? maybe other problems too (pics)

[reppinhigh22]

Aug 4, Day 83(from breaking ground) 2-top,Day 59 of 12-12 & since the Fim'd one broke soil. Day 14 Flowering 2top, Day 35 Flowering fim'd. Black Gold Potting soil for the 2top one and Black Gold Organic Potting Soil for the Fim'd one. I feed half strength Big Bud and half strength Iguana Juice Bloom. a half litre solution of each, 5 mins apart in the same feeding. I think the Fim'd one is yellowing off because of N deficiency or lockout. I used to feed them compost tea made from Nulife Organic Compost and handful from a bag of mushroom compost too. but I was told it might be too rich in N for flowering so I stopped using it. If I feed that compost tea it should replenish the N in the soil right? If thats what's needed. Any help would be appreciated thanks. Temps run from 79-84 degrees in my grow room, today was hot though it got to 88 in there.. Humidity is 40-50%

I didn't FIM in flower. I just used that method when it was in veg and using that to tell them apart in this thread. The pots are small.. is it too late to transplant? 210 watts of 2700k cfl lighting(105 each bulb) but I've only had the full 210 watts since the 25th, one bulb came broke when i ordered so i was at 105 for a week and before that i was at a measly 50watts. I figured if I used small pots they wouldn't grow too big. Being rootbound can cause stress and other problems too though probably huh? X_X

 

[scroglodyte]

transplanting now won't make a big difference at this point. keep the CFL's close. and root-binding can cause issues, yes.

 

[reppinhigh22]

Will I be alright? Should I add a bit of N somehow? any other noticeable problems? Thanks for your help Scrog.

I'd bump up the cal/mag next grow ( if growing the same strain ) and keep feeding N a few weeks into flower. And bigger pots like Scroglodyte mentioned.

I don't see a zinc def, so i doubt it's too much Phos. They don't rly look burnt. I'd say it's either ph lockout, or they are hungry. How often do you flush?

Question on your lights... Are they the same small CFL's as you use in your house? Not big grow ones? If so then you are not running 210w. More like 50w approx.

No they are full on 105 watt cfl bulbs I ordered online from 1000bulbs.com. that was mean ;( I already said I used to have little ones like you'd use normally but upgraded.

I feed my Big Bud & Iguana juice (same day) then i water(with molasses in it) two times after that before feeding again. I try to wait until they're pretty dry. This time I've done the water 3 times because I'm a bit worried about them. the pots are small so usually I get a lot of run off. is this good or bad?

Invest in a PH tester, everyone needs one soil, hydro, whatever. Test the water you feed, then test the runoff. PH is always step 1 for diagnosis...eliminate the possibilities. PH the nutes you feed also. The feed schedule sounds fine I guess, my friend does feed/water/feed/water at 50%. If it's not PH, they are hungry. purple stems means N,P,K or MG def. Lower leaf yellowing front to back means nitro def. Lower leaf yellowing uniformly with green veins means Mag def. Not enough light can probly cause some yellowing as well. I'm not sure what long term root bound can do besides stunt them.

Too much bloom food can cause salt lockup, what is the N-P-K of your total nutes? if your N is low and your giving extra P+K, then you may be doing more harm than good, more food may only make things worse, I would get your N-P-K level worked out, probably not enuff N in your bloom schedule....and then give this thread a look over>>https://www.rollitup.org/marijuana-plant-problems/158144-never-ending-abuse-phosphorous-bloom.html

it is a very good little thread to read with some very good info on 'bloom' products and this kind of problem happening in the flowering stage.

get the lights closer to your plants! lower leaves are changing be cause of light deficiency!

Actually made me lol

I topdressed a small pinch of bloodmeal and leaves are already looking less yellow in 24 hours.
