Grow Mediums First DWC..question

[pop22]

I've seen people running high ppms in their res, but my opinion is 1100 ppms is too high, or at least, for some plants. research I've done shows that 600-800 ppms from 3 weeks until finish is often the best. Plants can only take what they need, all that extra nutrient is just affecting ph, and possibly interfering with the roots ability to uptake. Mind you, this is just my opinion, but I'm running my res at 600 ppms now ( was 340 until 21 days ) and my plants are very healthy.

I have no idea what your saying by what's in the res

Res = Reservoir

You have a tank of water that you put nutrients into, that's your res / reservoir.

sorry Alex ...I mean whats your complete nutrient line up . your plant is well in bloom & looking very nice so far but the only thing you have mentioned about nutrients is tiger bloom & cal mag .You must have put more than that in your last "bucket?" what else did you use ? how much did you use ? .To help work out what the problem is we need to know everything that went into the reservoir / nutrient solution / bucket AKA "res" !!:stoneslap: ... Im making an educated guess your overfeeding & the more info you share the easier it will be to help out :Sharing One:

I know the res is the bucket but no nothing else. The water and those nutes. What else needs to go in?

 

[DWCocha]

tigerbloom will get the job done but is a base nutrient & usually complimented with other supplement bloom booster in the mid to late flowering stages to maximize health & yield .I would guess that lower PPM's but a good bloom booster added to your tiger bloom would be much better than just upping the tiger bloom mate .

A good PK booster for a week at the height of bloom is also an option & will help pack on the weight .Maybe have a look around ,check out some grows ,see what people are using for bloom & add a bottle or two to your range ?.

saying that the plant looks healthy from the pics & probably just suffering from some nute burn due to high PPM's :Sharing One:

I have ginormous by Humboldt as a pk booster. Should I change the res and use a different solution?

 

[DWCocha]

"wg's Cool" sounds like a good PK booster but im not sure how long you would run it ?.... I would start at 5ml per gallon this res & up by 5ml for the following 2 weeks so your at 15ml per gallon in the last week & then drop it ...you should be ready for a week of low feed & then a weeks flush by then

so yes I would make a fresh batch of nutes ...

add the cal mag first & make it 15ml if you where at 10ml & have noticed spots ?
then the 5ml per gal of Humboldt ginormous
then add tigerbloom upto 650 - 700 PPM
then PH to 5.8

monitor the PPM & if they go up = overfeeding
if they go down = underfeeding
if they remain stable = sweet spot

I think the ginormous may be a 1-2 week deal for a PK boost in the height of bloom & it may be an idea to contact them & ask how long they recommend using for ??? if you can get another bloom booster supplement for the whole bloom phase as well you should get a nice result .... most nute ranges will have a base nute like tigerbloom , a booster like bud candy or bigbud ect ...& a PK boost which im guessing ginormous is ?

it will definitely help the next stage of growth though :smoke:

hope this helps & happy growing :Sharing One:

When you guys are talking about PPM which scale are you talking about?

I am always always confused when people talk about PPM I don't understand it what so ever. 600 PPM could be 840 PPM to another person

Lets all just talk in EC and be done with it, no?
