just make sure in hydro, u do a thorough flush every 10 days or so, especially if you have a couple plants in your res. make sure your res temps hover round 65-70 and no higher. keep ur ppms low-under 500. and ur ph 5.7-5.95 ish

great advice Bones. next time, you would want ur plants finishing up like this so dont let them get so deficient. otherwise, very nice buds and they look like they will finish just dandy

if the soil was dry, and they perked back up, than yes they were underwatered. if they were droopy and got worse, than they were overwatered. something I notice don ur pics, r u feeding them yet? b/c they look ready for 1/3rd dosage of nutes or less

ur soil should be out of nutes. flowering plants need a healthy balanced nutritional diet.

cant tell too much from pics, but if u r reffering to stems, is quite normal for some strains. unlikely you would have a P deficiency in this stage of the game if u r feeding balanced nutes and have no other obvious signs of issues

yes, yes, good info. the taller, the more you have to.

no, but if you let it sit, u should be ok. you can add an air stone to boost up the o2 levels and speed evap of the chlorine. plants do need some amounts of Chlorine.

Ben, thanks for getting up to the plate. I agree with the post you wrote on RIU, however, the post pertains to P, not the K we are talking about here. No doubt those superbloom ferts with those crazy ratios are ridiculus. I would never use em. But K plays a pivotal and vital role, more so than...

woa dude, way over board on the N fert. dark green, shiny leaves, inhibited bud growth. exactly what i stated before the pics. not even the ppms, but the ratio of n way way way too high. drop the n ferts, like yesterday

they will be fine. no nutes for first three weeks is general rule of thumb. drop em down to 1/4 strength. let the rockwool dry out, as not supposed to be wet in dwc. prolly should flush her as well-

hey no prob. trust me, kind of ignore them, besides the ocaasional water, and they will grow out of it and continue on to be healthy happy plants

says in ur manual: TDS Meter General Usage and Calibration Instructions Proper Usage • Immerse the meter in the water/solution up to the maximum immersion level (2”). • Lightly tap or stir the meter to remove any air bubbles. – Pockets of air between the electrodes may...

ok, gotcha. than u were right to flush. good time for nutes is when the grow to the 4th node. and even then, start 1/4 strength and work way up to half

the salt build up is the white residue on the net cups and probably on those rocks. your ppm meter should automatically calibrate the temp range. u have a link of the ppm pen?

honestly, dont know why u r flushing. the only things these preemies need is to be left alone. just water when the soil is dry down to where u can stick ur finger in the soil. they need nothing else but to be ignored. u dont even have to worry about ph until u start feeding them. f u r intent on...

if u have rockwool in those net cups that is gonna need to be flushed from the top as well. u can see the salt build up on the one pic where it looks like the root tips are touching ur chair-big no-no if that is the case. very sensitive to bacteria. forget the 5.5 ph and go more for around 5.8...

overall looks like gonna be some great smoke. just keep in mind next time and try to pick up some stronger nutes. should keep the tea as part of their diet though.

still waiting for that research on how mj plants need little K during their life and that the bloom ferts are an old wive's tale.:sleep:

why would you be confused? c'mon man. go re read grow specialists posts and follow.:wall:

absolutely, usually over fert- a few days at 1400 + ppms will do that. just keep like you got em now and they should grow out of it within couple of days. 500 and under.
