What deficiencies am i battling?

[ReptillianSorcerer93]

Problem: these are my 3 girls showin all sortd of different deficiencies


Medium/grow method: biobiozz light mix 8lt fabric pots.

Feed: and supplements used: 3ml grow, 3ml bloom, 1ml topmax. (Biobizz). Calmag once a week.

water source: tap water left out 24/36hrs.

Strain/age: stilton special, sour livere, strawberry nuggets. All around day 36.

light used: 400w hps cooltube about 20" away.

Climate: steady around 27c 30% humidity. Humidity tends to rise about 50% when lights off.

Additional info. Each plant seems to be showing different deficiencies. I just cant put my finger on them!! Do i have to flush? I know when it comes to flushing you have to use 3x amountthe potsize. Do you still have to leave the water out 24hr? They need feeding today and i havnt got 72ltrs lying around.

They look dry and the nodes bunched up probably saying that with that low RH, the lights may be too close in your situation. Each grow and space is different. They look thirsty to me. Leaves turned up edges, not really glistening in the light exactly means dehydrated leaves...back off light. Up the Cal Mag 20%, and see what happens after a good feeding and a few days of consistent watering on schedule.

Nute dosage is per lt, i tend to fill a 2lt bottle up per plant and leave it out for 24/48hrs then stick my nutes in and feed. Unsure on the npk ratio, I'll just do a quick google search.

I just think he thought your nutes might be a little high. It might be if the lights are close and soil too dry...do s little flush. Move lights back 5" and keep watering schedule and not let soil get too dry. You can buy a little monitor that goes in the soil to make sure that the moisture level is good at the roots, cheap too.

8ltr fabric pots man, reaching about 30c at the moment with this 'heatwave' so ive turned the light down to 250w and raised it to about 25" (give or take) i did start watering every 3days from the start but have noticed there drying out abit quicker, especially in the enviroment.

Ive just fed them all 2ltrs, added calmag and pk 13/14. See how they do next 2days. I try and wait abit longer then too soon.
