Rootbound watering question

[vickydude]

Hey guys, i`m new to the growing and also to the forum, i`d like to appologise for/if i`m not posting where i should, and also for my bad english.

Due to lack of space, mu stealth box is kinda 70cm long, 40cm depth and 70cm high.
Light: 2x 45w 2700k CFL, 1x28w and 1x22w all 2700k CFL (140w total i guess)
strains: 3x automazing and 1x NLxBB auto
pots: here`s the problem. i really don`t know the size (25cm high, 18cm top diameter, 10cm bottom diameter) sooo i guess ~half a gallon - 1,2 liters

They are in flowering for few weeks, i`d say they are about 1month till over. (no trichs yet, hairs are 10-15% brownish, and those 10-15% are actually 1/2 of the tip brown, rest are white)
Sorry for getting into details....
MY QUESTION now... i am rootbound like a mothafa...after 20-24hrs from feed, the pots are like super light and dry, i am afraind to water too often because of root rot, so ... should i daily feed? once every 24h to keep em wet, or ..?

PS: i use General hydro Floranova bloom (i also tried to flush betwern veg and flower but after 1 day alot of the foliage started to die and i stoped)

Pot up now. Sounds like temps are f
To high. You should see trichomes within a week of flower I've never run autos but you pistls shouldn't be brown. Any nute burn? Mabey to much nutes.cfls don't produce much light so a strong feed will cause problems.Ph should be 6- 6.5 roughly.

Thenk you for replay. I can`t pot due to hight limit (a little taller and they get burnt from cfls, i constantly bend them so they remain at same distance).

The trichs are starting to appear, but vvvv few. (i`m not entirely sure on temps because of my lack of experience and beeing autos, so no 12/12 switch)

Pistils are: 85-90% full white, 10-15% are 1/2white and 1/2 brownish(brown tips)

About nute burn, i really don`t think there is a serious problem (only some leafes have small 1mm yellow @ the tip). I feed them once a day with 2ml floranova bloom diluted in 2.5l of tap water.

About the ph, i have no ideea, i don`t have the ph checker or ph up / down stuff.

So, is it ok? shall i keep feeding daily? or i might get a root rot?

PS: before they got root bound, i used to feed them like once every 3 days, but since the binding, i kept like that and i saw folliage droping hard, and then i started feed once every 36 hrs, and no leaf yellowing since then, but after 36 hrs the pot was completly dried, so i figured 24h feed (daily).

PS2: i also have a carbon filter and an air extractor inside the box.

bump please

Its fine to have multiple feedings in a light cycle. I'll start watering in flower once every other day to every day and end feeding twice a day. I do flood and drain with nets "scrog". Just try to figure out your timings to feed. Don't let them completely dry out, do your first watering in the first hour and check them every few hours till they feel lighter than feed some more. The more you can feed the bigger your harvest should be.

Thank you, so at best 2x watering in 24hrs i wont get root rot, sounds safe. TY

Hey guys, things are looking good so far with the daily feed, but since, the bud leaves are intense dark green (i know it`s N "overdose") but what concerns me is that they took this boat-like shape, they curled not as usual down... but .. up the margins/borders of the leaves, they look like dark green boats, and only the bud leaves, the fan ones are ok. I also see that this is happening just to 2/4 of my plants (1 nl x bb, and 1 automazing), rest 2 automazings are ok. Does anyone have any ideea if this is ok, or what does it mean?

 

[dabking]

How is your humidity, ph, ppm, temps? Do you check runoff ppm and ph?

 

[dabking]

By watering more often you could have possibly went a little over, another possibility is re activated salts built up in the medium. Extreme dry outs can also have that effect

i've seen that happen to fan leafs from heat and low humidity

 

[vickydude]

I am new to the growing, so i don`t have ph measurement tools and humidity, but the budz seem pretty happy i`ll post some pics soon, because you know pics or it didn`t happen...
