[smalltimebudtoker]

hi all, here are my babies looking ill, recently overwatered but then dried out and fed,,possible heat stress??? any bit of help will be greatful .... 12L buckets--in soil--PH 6.5 ish--2x 600w hps 2 and half weeks into flower, 1 ml of superdrive,10ml bio bloom, API PROPER PH 6.5 10 litres of water

 

[no clue]

Do you have drainage in those pots?

 

[smalltimebudtoker]

yes bud I do, that was the first thing I did with them...

 

[no clue]

There are some great growers on here...I am not sure what you got going on there..someone will help

 

[whodatnation]

Not good to feed dry roots. They're shocked some but will recover fine. Also, a little n throughout the rest of the grow us needed IMO. Too many bloom nutes fall way short on N.

what nitrogen products are there? does it come as a ready mixed formula (whole feed) or wha??

 

[ProfessorPotSnob]

Keep it evenly moist at all times for optimal growth .. Letting your roots dry out will enforce nutirnt deficiencies in acidic soils .. Youll have better growth and healthier plants and a more stable Ph as well ..

I would feed those plants with an addition of Cal/Mag asap ! And only allow maybe 10% max runoff ..

 

[ProfessorPotSnob]

I agree that you have overwaterd and underwaterd as well .. Hence creating a sickend root system which shows up within the leaves as shown .. Time to baby them and get em back on track now

I have some canna magnesium will this be any good?? but the only thing is when I measured the ph of it mixed in the water it read below 4.0?? is this a worry or does it not affect it?

Yeah watering with too low pH is horrible.....

 

[ProfessorPotSnob]

Soil Ph 6.5-6.8
Soiless 5.8-6.8
Hydro 5.5-6.2

These are the general Ph guidelines that I follow

1ml of super thrive? How often? Supr thrive is very good stuff but used more then one or two times in a plants life is abuse which can and will cause problems like toxicity of micros, really you may better off putting the super thrive down. A high quility nute will have all your plants need in the correct amount. You should also look and see how compact your soil is which will suffocate your roots and look like over watered. This is just my opinion under watered I have has plants that start to wilt when the soil still moist because the pot was to small this also happens to outdoor grower.

hmmm ok ok, ill have to buy some ph up,, with all the nutes mixed up, bio bloom and magnesium and nitrogen should I aim for the 6.0-6.5 ph level?? I think I will spray on the magnesium and nitrogen and pour in the bloom fert, what do you recommend? thanks

SuperThrive is amazing, the synthetic auxin I use to boost flowering or I should say induce flowering. Too much Auxins will cause increase in ethylene witch is the cause of problems. A little rarely is AMAZING too much one time is like dropping an A-BOMB.

yeaaaaaah I will hold back on the super drive! I didn't think such a lil amount can cause so much harm!! hey im a newbie and I have learnt the hard way, im going to my hydro shop first thing to get some nitrogen I hope things start looking up
